ライダの振動特性が二輪車の直進安定性に及ぼす影響の解析

抄録

A six-degree-of-freedom model and a twelve-degree-of freedom model incorporating a rider's vibrational characteristics have been developed. The models include a mechanical model of the rider's body which consists of a leaning motion of the upper body and a lateral movement of the lower body. Damping properties and natural frequencies of weave and wobble modes were calculated using these models. Conclusions are drawn about effects of the rider's vibrational characteristics on the stability of motorcycles during straight running from the calculations in the six degree of freedom model. Implications for accurate modeling of motorcycle stability are derived from differences between the calculations in the twelve-degree-of-freedom model and running experiments.
