Abstract
A virtual road simulator technology for motorcycles was established as a method for predicting motorcycle fatigue strength due to loading during running, that enabled prediction of dynamic behaviors and stresses during the road simulator durability test. This technology was made up of Finite Element Method, Multi Body Simulation, Road Simulator control, and fatigue analysis. The study enabled reproduction of the behavior of motorcycles using the simplified model of motorcycles and test rig including component Finite Element models. As a result, prediction of fatigue life, damage distribution, and stress waveforms of the high-stress regions in a Road Simulator durability test was achieved.
