Design and Analysis of Front Suspension for Light Duty Vehicle

Suspension unit is the term given to the system that consists of springs, Shock Absorbers and Linkages that connects a vehicle body to its wheel. Suspension unit has many purposes which are vehicle handling, passenger's comfortable, avoiding noise and bumps to the vehicle, etc. Independent suspension typically offers better ride quality and handling characteristics, due to the ability of each wheel to address the road undisturbed by activities of the other wheel on the vehicle. Independent suspension requires additional engineering effort in development versus a beam or live axle arrangement. Introducing Independent Suspension in Commercial Passenger Vehicles will increase the comfortable in long journey. Existing suspension units in the commercial passenger vehicles have only the leaf springs which are connected between the vehicle chassis and wheels. So the movement on one side will affects the wheel on the other side and whole body will affected by the shock. Therefore by designing Independent front suspension unit for heavy commercial passenger vehicle will result in absorbing the most part of the shocks by the suspension unit and also the independent movement of wheels. Here the existing model was studied and new design on independent suspension was created for front suspension unit of commercial passenger vehicles. The prototype Model of the design work was created with the help of Pro/Engineer Wildfire 2.0 and Solid Works 2008 3D CAD Design Software's and COSMOS Simulation Package was used to undergo the analysis operation.
