A Computer Simulation for Motorcycle Rider-Motion in Collision

Article of Honda R&D Technical Review Vol.15 No.1


In computer simulation method for motorcycle rider motion in collision of motorcycle to car, we have validated the computer simulation results in two cases in which a motorcycle runs into a running car side with 45 degree and 90 degree angles. The simulation software of explicit finite element method (FEM) has been used, because of its capability for expressing accurate shape and deformation. The mesh size was determined by considering a simulation accuracy and a calculation time, and FEM model of a motorcycle, an air bag, a dummy, a helmet and a passenger car were built. To shorten calculation times, a rigid body was adopted to a part of the model and contact regions were limited. As the results, higher accuracy of head speed and posture at the ground contact of dummy was obtained in simulations of the two cases this time. Calculation time of the two cases was about 50 hours with the computer of 14.4Gflops.
