 Abstract

A leaf spring is a simple form of spring, commonly used for the suspension in wheeled vehicles. Leaf Springs are long and narrow plates attached to the frame of a trailer that rest above or below the trailer's axle. There are monoleaf springs, or single-leaf springs, that consist of simply one plate of spring steel. These are usually thick in the middle and taper out toward the end, and they don't typically offer too much strength and suspension for towed vehicles. Drivers looking to tow heavier loads typically use multileaf springs, which consist of several leaf springs of varying length stacked on top of each other. The shorter the leaf spring, the closer to the bottom it will be, giving it the same semielliptical shape a single leaf spring gets from being thicker in the middle. Springs will fail from fatigue caused by the repeated flexing of the spring. The aim of the project is to design and model a leaf spring according to the loads applied. Presently used material for leaf spring are forged steel. In this project we are going to design leaf spring for the materials Mild Steel and composite material Glass Carbon by varying reinforcement angle. We are going to check the strength variations while changing reinforcement angle. For validating this design we are conducting FEA Structural Analysis is done on the leaf spring by using two different materials Mild Steel and Glass Carbon. Modal and fatiuge Analysis is also done. Pro/Engineer software is used for modeling and ANSYS is used for analysis.

 Abstract

Differential is used when a vehicle takes a turn, the outer wheel on a longer radius than the inner wheel. The outer wheel turns faster than the inner wheel that is when there is a relative movement between the two rear wheels. If the two rear wheels are rigidly fixed to a rear axle the inner wheel will slip which cause rapid tire wear, steering difficulties and poor load holding. Differential is a part of inner axle housing assembly, which includes the differential rear axles, wheels and bearings. The differential consists of a system of gears arranged in such a way that connects the propeller shaft with the rear axles. The main objective of this paper is to perform mechanical design of differential gear box and analysis of gears in gear box. We have taken Stainless steel,aluminium alloy,magnesium alloy,structural steel materials for conducting the analysis. Presently used materials for gears and gears shafts is Cast Iron, Cast Steel. So, in this paper we are checking as the other material for the differential gear box for light utility vehicles so, we can reduce the weight.

 Abstract

In today's world, safe operation of the vehicle demands that the operator be able to maintain absolute control of the vehicle's critical operating dynamics: (1) Control of the direction of motion of the vehicle (steering) (2) Control of the velocity of the vehicle, i.e. the ability to slow and fully stop the vehicle (braking). This paper provides an overview of electric assisted vehicular steering including brief description of various conventional systems and the basics of steering; particular attention in addressed to -Electric Power Assisted Steering (EPAS). Electric power assisted steering has temped automotive engineer since the 1950. Even so, the promise of smaller, lighter, and more efficient systems never quite matched the low cost and performance of hydraulic power assisted steering (HYPAS) advance in microelectronics; however have rekindled interest in EPAS. Motor drive stages, electronic control units and torque sensor can now be manufactured relatively cheaply. These components, coupled with complex control algorithms implemented in software can rival or better the performance and functionality of conventional hydraulic steering systems.

 Abstract

A computational capability is evolved for the gold standard design of radial drilling gadget shape to satisfy static stress and natural frequency necessities the use of finite element idealization. The radial drilling device structure is idealized with body elements and is analyzed by way of the usage of specific combos of move sectional shapes for the radial arm and the column. From the consequences acquired, the best mixture of cross sectional shapes is recommended for the structure.

 Abstract

This project describes the concept, design and prototype implementation of a wheeled pole-climbing-robot based on Ferromagnetic adhesion. Pole climbing robots have become an interesting area for research in the last years. Several robots have been developed to solve this given problem. Every construction has its own advantages and disadvantages. The goal of this work was to design another pole climbing robot that uses a ferromagnetic adhesion principle. It was not the forceful goal to create a fully optimized working robot but rather to learn the design and construction steps, which are needed for a new product from the engineering point of view.

 Abstract

Most of the industries are having a various types of reciprocating machines for performing machine operation on small size of work. Usually shaper, broaching machine and planner are used for machining a small area of work with less quantity. These machines are used for machining very small area of plain surface, vertical surface, angular surface, grooving etc. It removes the materials from job only at forward stroke. So it takes more machining time to complete the product. In order to overcome this problem, a small dual shaper machine is developed for machining two work pieces at a same time. In this machine, it has both the direction of ram movement and it removes a material from two work pieces simultaneously. So, the machining time will be reduced and the production rate will be increased.

 Abstract

In this study, we developed a completely contactless air conveyor system for transporting and positioning planar objects. The air conveyor forms a thin film underneath the object for support and simultaneously generates a controlled airflow that results in viscous traction. It is potentially applicable in the manufacturing process for semiconductor wafer or flat foodstuffs, where mechanical contact is expected to be avoided during transportation of the products to minimize contamination. The air conveyor employs duplicated arrays of actuating cells that are square pockets with a surrounding dam. A simple model is proposed to characterize the viscous force. The theoretical analysis reveals that the total force is the composition of an actuating force generated in the pocket areas and the side areas and a drag force generated in the dam areas. Experimental investigations are conducted on the basic characteristics of the film pressure distribution and the viscous force. The results show that the air film pressure is symmetrically distributed in the width direction but non- symmetrically distributed in the length direction. The viscous force increases if the suction flow rate is enlarged or the gap thickness is narrowed. Comparison of the experimental results and the calculated results indicates that the model can provide an accurate prediction. A proportional-integral-derivative (PID) controller is applied for 1D-position control and position tracking. The actuating direction is selected using fast switching valves and the amplitude of the actuating force is adjusted using a control valve to vary the suction flow rate. The simulated and the experimental results verify the feasibility of the air conveyor system and the control method.

 Abstract

The automatic rain sensing car wiper system is used to detect rainfall and it is used to activate any automobile's rain wipers without driver interaction. The system was developed to avoid driving distractions and hence allow the drivers to focus on their primary task of driving. The distraction get rid with the development of this product is the manual adjustment of windshield wipers when driving in precipitation. The few seconds that a driver takes their attention off the road to adjust a knob while driving in poor weather conditions

 Abstract

In standard two-wheel steering vehicles, the rear wheels do not play any role in association with the steering and follow the path of the front wheels. In four wheels steering the wheels can be rotated either left or right as per the requirements. Rear wheels can be rotated in same direction as the front or in opposite direction. The four-wheel system is designed to function in 3 modes namely, in-phase rotation, counter-phase rotation and zero rotation. The steering systems are designed to give the best control designed for the vehicle. The vehicles are designed with steering control to the front wheels or in certain cases steering control is given to the rear wheels. The dual axle steering system shows the working of different motion of wheels with respect to various turning arrangements.
