摘　　要：基于虚拟样机技术,建立摩托车多体动力学模型,以B级路面谱为振动激励对某款摩托车进行随机振动分析。综合研究摩托车悬架弹簧刚度和阻尼、后悬架弹簧与摆臂连接位置对舒适性的影响。基于虚拟样机技术的产品设计,大大提高了产品设计效率,缩短了产品设计周期。A multi-body dynamic model of a motorcycle for simulation is built with ADAMS. Simulation of ride comfort of the motorcycle is carried out with a uneven road file. The influence of the stiffness, damping and the distance between the rear spring and the rear link on the comfort has been investigated. This practice shows that the product design by using virtual prototype technology can improve the design efficiency and shorten the design periods.
