The main challenge that arises in the design of a motorcycle frame is its effect on the functionality on the vehicle, its effect on ride comfort and its durability. While functionality and ride comfort due to frame can be evaluated by subjectively testing it before the product reaches customer, evaluation of its durability is a complex process. This work is an investigation of the frame body of a 100 cc vehicle in India. These vehicles are subjected to endurance tests on a rough road at vehicle level to quantitatively evaluate their frame durability. However, such tests require significant time and cost, so an attempt has been made to develop a virtual rough road simulator to extract forces involved in it and testing the frame at component level with those loads on a test rig. Also durability results were compared and analyzed with the track data and frame test rig.
