摘要
Aim To study the transient response of motorcycle with one tire colliding on ground. Methods Taking the colliding velocity as an independent variable, the changing law of the biggest collision inertia load of motorcycle′s sprung mass, unsprung mass and driver was studied, while its front and rear tire colliding on ground respectively.Results and Conclusion According to the working conditions of motorcycle shock absorbers and the characteristic of response curve, the transient response of the acceleration, the velocity and the displacement were discussed section by section. And the result of simulating the actual JH125 motorcycle was given.
目的研究摩托车越障时单轮冲击地面的瞬态响应，方法以落地垂直速度为自变量，分析了前后轮分别跌落时，摩托车驾驶员及簧上、簧下质量最大冲击惯性载荷的变化规律，结果与结论根据摩托车减振器的工作工况及响应曲线的特性，分段讨论了对应的加速度、速度、位移的瞬态冲击响应，并以JH125摩托车的实际参数进行了仿真计算。
