Secondly, in the elastic kinematics simulation, the tire as a rigid body, without considering tire stiffness, which is a factor of error. 其次，在弹性运动学模拟中，把轮胎视为一个刚性体，没有考虑轮胎刚度，这也是产生误差的一个因素。 - 2
Further topics include kinematics, particle dynamics, motion relative to accelerated reference frames, work and energy, impulse and momentum, systems of particles and rigid body dynamics. 更进一步探讨运动学，质点动力学，于加速座标系上之运动行为，功，能量，冲量，动量和质点系统与刚体动力学。 - 3
But there are only basic info of geometry, topology and partial kinematics in the CAD model in STEP. The description on feature of multi-rigid-body dynamics is hardly blank. 使用现有的产品数据表达与交换标准STEP只能描述CAD模型几何、拓扑和部分运动学信息，对多刚体动力学特征的描述一直是特征模型中的一个空白。
