Evaluation Method of Motorcycle Fatigue Strength Using Road Simulator 951817

Studies using a road simulator in an endurance testing have been developed in the field of automobiles and widely utilized in recent years.In the endurance testing of motorcycles, on the other hand, the mainstream technique has been to repeat riding over cams on rotating drums. As it is impossible for this technique to accurately reproduce the loads encountered during driving on a rough road, it had to be made up in other tests so that improvement has been desired in both accuracy and efficiency.A study was done on a technique to accelerate endurance testing while retaining correlation with loading caused by the irregularities of public road surfaces. The technique has enabled us to realize bench endurance testing having a high degree of correlation with the loading of riding public roads by the use of a road simulator for motorcycles, which activates a front axle in two directions, longitudinal and vertical.The technique can be applied to all on-road motorcycles, thereby enhancing development efficiency.
