Experimental Evaluation of a Non-Intrusive Automotive Suspension Testing Apparatus

Proper performance of a vehicle's suspension system is required to ensure safe, comfortable operation of a vehicle. A suspension-testing device that can determine the condition of the suspension system, specifically the dampers, has been designed. The tests described by this paper seek to evaluate the performance of the device by testing vehicles and comparing to other methods of measuring suspension system performance that are currently in use. The suspension-testing device has the ability to discover degraded performance of the suspension system through a 2-minute test with the vehicle in operating condition.
