Helical and spur gears.pptx
Helical and spur gears are types of gears that can be used to transmit torque between parallel shafts. Spur gears have straight teeth parallel to the shaft axis, while helical gears have teeth wrapped in a helix around the gear. Helical gears provide a smoother drive than spur gears due to their gradual engagement of teeth. Key terminology for gears includes pitch circle, pitch diameter, addendum, dedendum, diametral pitch, and module. Gears can be classified based on shaft positioning, peripheral velocity, and type of gearing such as external, internal, rack and pinion.
Gear Drives.pptx
This document discusses different types of gear trains used to transmit power between rotating shafts, including:
1. Simple gear trains with one gear on each shaft to transmit power between parallel shafts.
2. Compound gear trains with more than one gear on a shaft used to bridge space between driver and driven gears. Speed ratios are calculated by multiplying the tooth ratios of each gear set.
3. Gears can be spur, helical, bevel, worm or rack and pinion, with different arrangements depending on the relative positions and angles of the shafts. Compound and epicyclic gear trains allow for greater speed reductions than simple trains.
Kinematics of Gears.ppt
Gears are used to convert between high speed and low torque to low speed and high torque. They engage teeth to transmit high forces through rolling contact. The basic law of gearing requires the line of contact between gear teeth to pass through a fixed pitch point. Spur gears have parallel axes while helical gears operate more smoothly. Worm gears can transmit torque at right angles but are inefficient. Bevel and spiral bevel gears allow right angle power transmission. Gear trains can provide speed reductions and torque increases through combinations of gears.
Gear trains by k.santhosh
This document discusses different types of gear trains:
1. Simple gear trains have one gear on each shaft and transmit motion between shafts. Speed ratio is the inverse of the gear tooth ratios.
2. Compound gear trains have more than one gear per shaft, allowing greater speed reductions over longer distances than simple trains.
3. Reverted gear trains have the first and last gears on the same shaft, so their motions are in the same direction.
4. Epicyclic gear trains allow shaft axes to move relative to a fixed axis, like in planetary gears. Speed ratios can be calculated using tabular or algebraic methods.

Final Drive_Differential
The differential is an essential part of any four-wheeled vehicle that allows the wheels to rotate at different speeds, such as when turning. It splits the engine torque between the two output shafts so each wheel can spin at its own rate. Modern differentials come in two main types: open differentials and limited-slip differentials. Open differentials distribute equal torque to both wheels but can cause wheel slip in turns, while limited-slip differentials provide more torque to a slipping wheel for better traction.
Propeller shaft
The propeller shaft transmits power from the gearbox to the differential. It is connected to these components by universal joints on each end, with a slip joint also included between one universal joint and the propeller shaft. The propeller shaft is a tubular steel shaft that can withstand high torsional stresses and vibrations at high speeds. It transmits the rotary motion from the transmission to the rear wheels through the differential.

Transmission system_clutch
The document discusses various types of vehicle transmission systems. It begins by defining the transmission system and its main components like the clutch, gearbox, propeller shaft, etc. It then lists the key requirements of an effective transmission system. The rest of the document focuses on different types of clutches used in vehicles - including single plate, multi-plate, cone, centrifugal, electromagnetic, and torque converter clutches. For each type, it provides details on parts, operation, applications, and advantages/disadvantages.
Materials in automotive design
Channel, box, and tubular sections are commonly used materials in automotive design. Channel sections provide good resistance to bending, box sections provide good resistance to both bending and torsion, and tubular sections provide good resistance to torsion. The key requirements for automotive materials are that they be lightweight, economically effective, promote safety, and can be recycled. Lightweight materials improve fuel efficiency, safety depends on crashworthiness and penetration resistance, and recycling addresses environmental concerns. A variety of materials are considered including metals, composites, and foams to achieve the different requirements.
Loads acting on frame
Five basic load cases:
– Bending case
– Torsion case
– Combined bending and torsion
– Lateral loading
– Fore and aft loading
chassis frame
The document discusses different types of vehicle chassis frames. It describes ladder frames, integrated/monocoque frames, semi-integral frames, tubular space frames, and backbone frames. Ladder frames use two longitudinal beams connected by cross-members and were commonly used in early cars. Integrated/monocoque frames combine the frame and body into a single welded structure, providing better handling and fuel economy. Semi-integral frames have a partial frame at the front. Tubular space frames use dozens of welded tubes for strength from any direction but are complex and expensive. Backbone frames have a strong central tube that connects the front and rear suspensions.
Automobile and chassis
An automobile is a self-propelled vehicle used for transporting goods and passengers on the ground. Examples include mopeds, scooters, motorcycles, cars, jeeps, trucks, tractors, ships, aircrafts, and rockets. The history of automobiles began in 1801 with the steam carriage and progressed through important milestones like the first gas-powered automobile in 1885. Automobiles are classified based on their purpose, fuel used, and capacity. The main components of an automobile include the chassis, engine, brakes, steering system, and wheels. The chassis provides the main supporting structure and consists of the engine, brakes, steering, and wheels mounted on a frame.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Hierarchical Digital Twin of a Naval Power System
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Gear and gear train
- 1. In order to avoid the slipping, a number of projections (called teeth) as shown in Fig. , are provided on the periphery of the wheel A, which will fit into the corresponding recesses on the periphery of the wheel B. A friction wheel with the teeth cut on it is known as toothed wheel or gear. Gear 1
- 2. Advantages and Disadvantages of Gear Drive The following are the advantages and disadvantages of the gear drive as compared to belt, rope and chain drives : Advantages 1. It transmits exact velocity ratio. 2. It may be used to transmit large power. 3. It has high efficiency. 4. It has reliable service. 5. It has compact layout. Disadvantages 1. The manufacture of gears require special tools and equipment. 2. The error in cutting teeth may cause vibrations and noise during operation 2
- 3. Circular pitch It is the distance measured on the circumference of the pitch circle from a point of one tooth to the corresponding point on the next tooth. It is usually denoted by pc . Mathematically, Circular pitch, pc = π D/T where D = Diameter of the pitch circle, and T = Number of teeth on the wheel. If D1 and D2 are the diameters of the two meshing gears having the teeth T1 and T2 respectively, then for them to mesh correctly, 3
- 4. Condition for Constant Velocity Ratio of Toothed Wheels–Law of Gearing Since the speed ratio (or velocity ratio) of gear train is the ratio of the speed of the driver to the speed of the driven or follower and ratio of speeds of any pair of gears in mesh is the inverse of their number of teeth, therefore N1 = Speed of driver in r.p.m., N2 = Speed of intermediate gear in r.p.m., T1 = Number of teeth on driver, T2 = Number of teeth on intermediate gear, gear ratio or 4
- 5. Gear Trains two or more gears are made to mesh with each other to transmit power from one shaft to another. Such a combination is called gear train or train of toothed wheels. Simple Gear Train It may be noted that the motion of the driven gear is opposite to the motion of driving gear. 5
- 7. Reverted Gear Train When the axes of the first gear (i.e. first driver) and the last gear (i.e. last driven or follower) are co-axial, then the gear train is known as reverted gear train 7
- 8. Epicyclic Gear Train 8 https://youtu.be/sNBooUaVf7w An epicyclic gear train (also known as planetary gear) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates to carry one gear, called the planet gear or planet pinion, around the other, called the sun gear or sun wheel.
