Structural analysis of steering yoke of an automobile for withstanding torsio...eSAT Journals
Abstract
The steering columns in a steering system are one of the main devices of an automobile. It is a very important part to attain stability and
steady movement of the vehicle. It consists of two yokes, one on each shaft, connected by a cross-shaped intermediate member i.e.
spider. Motion transmission system of vehicles consist several components which sometimes encounter unfortunate failures. Some
common reasons for the failures may be manufacturing and design faults, maintenance faults, raw material faults, material processing
faults as well as the user originated faults. In this paper finite element analysis of the component is carried out to find the stress and
displacement of the final product. For modeling of the component, CATIA V5 R17 software is used. Preprocessing work like meshing
and analysis work is carried out in HYPERWORKS software. Using FEA analysis, we can identify the nature and characteristics of
stresses acting on the yoke and also evaluate the influence of the loads/ mass/ geometry/ boundary conditions over the yoke.

RELIABILITY BASED DESIGN OF A GEAR BOXIJERA Editor
Reliability is the probability that a system, component or device will perform without failure for a specified period of time under specified operating conditions. The concept of reliability is of great importance in the design of various machine members. Conventional engineering design uses a deterministic approach. It disregards the fact that the material properties, the dimensions of the components and the externally applied loads are statistical in nature. In conventional design this uncertainties are covered with a factor of safety, which is not always successful. The growing trend towards reducing uncertainty and increasing reliability is to use the probabilistic approach. In the present work a three shaft four speed gear box and six speed gear box are designed using reliability principles. For the specified reliability of the system (Gear box), component reliability (Gear pair) is calculated by considering the system as a series system. Design is considered to be safe and adequate if the probability of failure of gear box is less than or equal to a specified quantity in each of the two failure modes. . All the parameters affecting the design are considered as random variables and all the random variables are assumed to follow normal distribution. A computer program in C++ is developed to calculate the face widths in bending and surface failure modes. The larger one out of the two values is considered. By changing the variations in the design parameters, variations in the face widths are studied.
Analysis of Rack and Pinion under dynamic conditionsnagaraju kondrasi
Based on physical and thermal properties graphite cast iron has got more strength than sand cast Mg alloy and it is clear from the results that the load carrying capacity of former is larger than the later. Hence Graphite cast iron is preferred for the manufacture of rack and pinion.
In static structural analysis the total deformation and von - mises stresses are more in sand cast Mg alloy than graphite cast iron. Hence graphite cast iron has better strength than Sand cast Mg alloy.
In modal analysis the number mode shapes are higher for graphite cast iron than sand cast Mg alloy.
Under transient conditions the total deformation of Graphite CI is less than that of Sand cast mg alloy. Hence former is preferred under Transient conditions.
Under fatigue loads the damage is more in sand cast Mg alloy. Hence graphite CI is preferred for manufacturing of Rack and pinion.
Hence Keeping all the analysis in view the graphite cast iron is preferred over sand cast Mg alloy.
Comparative finite element analysis of metallic spur gear and hybrid spur gearIAEME Publication
Gear is the special division of Mechanical Engineering concerned with the transmission of power and motion between the rotating shafts. In this study, a lathe machine tumbler gear mechanism used for threading purpose is taken and applied finite element analysis methodology on each metallic
spur gears and also FEA analysis is done for hybrid spur gear with same applied load and condition to check comparative stress analysis of both metallic spur gears and hybrid spur gears.
In many cases wherever material handling equipment gear drives are used because of their efficient transmission of power. But disadvantage o f this system are whenever power shut down occurs or may be mechanical failure occurs are inpu t side of the system. If this situation occurs,guarantee of rotation of the shaft cannot be predic ted. It can move in both the direction,either it can continue moving in same direction because of in ertia or it may move in opposite direction because of gravity of the load. Moving in the rever se direction is also called as back driving [1]. To prevent back driving self locking gears can be p rovided,which doesn�t move in opposite direction. The project implemented aims at self locking proper ty by usage of worm pair which are connected to each other in mesh pattern. The advant age of implemented system is simple and robust in construction. And we can achieve efficien cy of around 90%,where as conventional system has efficiency of only 40%.

Design and fabrication of gearbox with inboard braking of an all terrain vehicleabdul mohammad
We design, build and test an off-road race vehicle each year. During this season, a customized gearbox with inboard braking is typically designed as a reduction after the Continuously Variable Transmission. A preliminary design was first prepared keeping in the mind, the guidelines and rules issued by SAE. Indian standards for driver space and ergonomic preference transmission type was selected and designed according to requirements of the driver. Hence after ensuring safety, the design was finalised and fabricate it. Moreover, the axle braking is to slow down or stop the vehicle safely and effectively by converting kinetic energy into heat. It is the one of the main safety of a vehicle. The goal of the project is to develop a lightweight, compact gear reduction that will increase the efficiency and durability of the vehicle. And also, in addition we have provided hydraulic braking for the drive shaft (i.e. known as inboard braking) for which the calliper is mounted to the gearbox itself. The pedal must actuate the master cylinder without any usage of cables and should be capable of locking four wheels in static condition and dynamically on paved and unpaved surfaces. While designing a brake system for a vehicle that can produce adequate braking force to meet competition regulations while being as light as possible. A budget, timeline, proof of design, fabrication and testing will also incorporate in the report.
