Development of Component Level Testing Method for Passenger Car Wheels

In the design of automotive wheels, safety is a crucial factor. Wheels contribute to a vehicle handling, braking and overall driving performance. Wheel are designed to withstand the weight of the vehicle and force generated during driving. It is the medium which isolates the obstacles coming from roads. Impact tests are usually performed after the wheel has been already designed and first prototypes have been produced. The test involves 90-degree free fall dynamic impact to determine the wheel resistance to deformation, cracking and overall structural failure. Its best method to captured the exact results during and post impact. These results are contributes the major role in development of automotive wheel rims. Most of the OEM’s are validating the wheels in virtual environment as FEA analysis software and LS Dyna. In this paper detailed procedure of testing of wheels at component level is presented. This work determines the development of test procedure for passenger car wheels in the Laboratory by using impact test rig facility and details of test rig development. This work reduces the lead time development of wheels for passenger vehicles.
