Analysis of Front Suspension Bracket under Pretension and Service Load




Service Load on Bracket, Suspension bracket


Automotive chassis is the back bone of an automobile, which acts as the frame to support the body and other different parts viz., bumper, front suspension bracket, engine mount bracket, fuel system, etc., of the vehicle. Chassis frame and bracket are the most critical element that gives strength and stability to the vehicle under different conditions. So the frame as well as brackets should be strong so that it can withstand shocks, twists, stresses and vibrations to which it is subjected while vehicle is moving on road. Thus strength and stiffness are the two important design considerations. Frame and brackets are connected by using welding as well as bolts and nuts. The main function of the front suspension bracket is to properly balance and transmission on the vehicle chassis, suspension bracket is an important part of the vehicle to reduce the vibration and noise, by which smooth ride of the vehicle can be achieved. Vibration and strength of suspension bracket has been continuously a concern which may lead to structural failure if the resulting vibration and stresses are severe and excessive. Present work mainly focused to select the best material for the front suspension bracket of the automobile. Non-linear static analysis is carried out on the bracket to determine the behaviour i.e., Stress and Displacement for different material. ex-mild steel, aluminium and cast iron. Bolt slippage calculation is considered here to know the friction co-efficient between bolts and nuts. Since it is easy to analyze structural systems by finite element method, the front suspension bracket is FE modelled using HYPERMESH and the FE analysis is done using the ABAQUS.
