This document discusses a model of a four wheel steering mechanism. It begins with an introduction to four wheel steering and its benefits over traditional two wheel steering systems, such as improved maneuverability and reduced turning radius. The objectives are then stated as building a physical model of a four wheel steering mechanism and understanding its advantages. The methodology and components of the model are described, including a rack and pinion system to steer the front wheels connected via bevel gears to another rack and pinion to steer the rear wheels. The working principle is explained, with the rear wheels steering in the opposite direction of the front wheels at low speeds for improved cornering, and in the same direction at high speeds for quicker lane changes.

Different Modes in Four Wheel Steered Multi-Utility Vehiclesresearchinventy
Four wheel steering is the innovative technology in which research is going on. The front-to-rear wheel alignment plays a significant role in the directional stability of a vehicle in a good manner. Four wheel steering is the system that allows the rear wheels to turn for maneuvering, rather than just follow the front wheels. The system is employed by some vehicles to improve steering response, increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed. In Four Wheel Steering System, the rear wheels do play an active role for steering, which can be guided at high as well as in low speeds. In this paper we made a four wheel steered vehicle for the analysis of four wheel steering systems (4WS). Apart from normal front wheel steered vehicle our designed model can work in all four modes of four wheel steering. The four modes include front wheel steering, 360 degree rotation of vehicle with in the position, parallel parking mode and shorter radius mode. 4WS is one of the devices which are used for the improvement of vehicle maneuverability and stability. Another significant finding is the effect of vehicle add-ons which showed how a multi utility vehicle can be made by giving a floor cleaning machine with it. We introduced Neodymium magnets to attract metal scraps, which helps us to clean the floor. It is expected that our different modes will be very beneficial to everyone who involved or interested in the automotive design, steering modes, analysis, performance assessment and applications of various types of four wheel steering systems.
An approach to parallel parking and zero turning radius in automobilesIjrdt Journal
Conventional steering mechanism involves either the use of Ackerman or Davis steering systems. The disadvantage associated with these systems is the minimum turning radius that is possible for the steering action. This difficulty that is associated with the conventional methods of steering is eliminated by employing a four wheel steering system. In this system, the wheels connected to the front axles are turned opposite to each other, and so are the wheels connected to the rear axle. The wheels on the on left half vehicle rotate in one direction and the ones on the right half of the vehicle rotate in the opposite direction. This arrangement of the wheels enables the vehicle to turn 360 degrees, without moving from the spot, i.e. the vehicle has zero turning radius. This helps in maneuvering the vehicle in tight spaces such as parking lots and within small compounds.

final year project report by mechanical engineering student of career point university kota. The Soft Car design proposal has swing 90 degrees. It can pull up alongside a parking space and drive in sideways.
Today parking a car on side of the road is major problem. Every time while parking and removing car from the parking space consumes fuel and space. Also we have to leave some space in the front and back side of car so that removing it outside would be easy. We also have to reverse car several time while parking and crashes occurs sometimes. So to overcome this problem we designed a prototype showing transverse car parking mechanism. The mechanism is attached with the car from the bottom side which will lift the car on four small sized wheels by means of pneumatic or hydraulic system and then it moves transversely. The four auxiliary wheels can flip inside so that when we are not using mechanism the ground clearance of the car will be unaffected. This type of mechanism can also use as in-built jack to replace damaged wheels. This type of mechanism will be very much useful for people in emergency cases like removing car from the road in case it’s not starting and this mechanism will work on the battery.
A Four wheel steering system also known as Quadra steering system. In this paper, both front
wheel and rear wheels can be steered according to speed other vehicle and space available for
turning. Quadra steer gives full size vehicle greater ease while driving at low speed, improves
stability, handling and control at higher speed.
Production-built cars tend to under steer or, in few instances, overseer. If a car could
automatically compensate for an under steer overseer problem, the driver would enjoy nearly
neutral steering under varying conditions. Four wheel systems is a serious effort on the part of
automotive design engineers to provide near-neutral steering.
This system finds application in off-highway vehicles such as forklifts, agricultural and
construction equipment mining machinery also in Heavy Motor Vehicles. It is also useful in
passenger cars.
It improves handling and helps the vehicle make tighter turns. This system is used to minimize
the turning radius.
Four-wheel steering (or all-wheel steering) is a system employed by some vehicles to improve steering response, increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed.
4-WHEEL STEERING SYSTEM MECHANISM USING DPDT SWITCHIAEME Publication
In standard 2 Wheel Steering System, the rear set of wheels are always directed forward and do not play an active role in controlling the steering, thus it results in increased turning radius. While in 4 Wheel Steering System, the rear wheels do play an active role for steering and helps to decrease the turning radius. Vehicle parking and driving in city conditions with heavy traffic in tight spaces, driving would be very difficult due to larger wheelbase and track width. Hence there is a need of a mechanism that can decrease the vehicle’s turning radius.
This is about the Electronic power steering operated without any hydraulic fluid and operated by the separate motor getting the power from the battery instead of power taken from the engine.
Design & Synthesis of Four Wheel Steering MechanismIRJESJOURNAL
Abstract: The objective of this paper is to analyze the steering mechanism of an automobile for the purpose of making a mechanism which is capable of turning all the four wheels of the automobile simultaneously whether in same or different directions as per the requirement so as to utilize the steering mechanism of the automobile in an effective way and to reduce the efforts applied by the driver to park the vehicle in a limited space or to reverse the vehicle direction. The steering mechanism plays a vital role to balance all the four wheels of the automobile while a vehicles moves in a definite direction. In this paper an attempt has been made to develop such a mechanism which can turn all the four wheels of automobile simultaneously which could be beneficial to make an effective turn as well as can assist in parking the vehicles. The radius covered by the vehicle to reverse its direction by both two wheel and four wheel steering mechanism has been calculated as well as experimentally evaluated.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
