摘要
本文以微分几何为工具,推导出做曲线运动的点的二次加速度表达式、刚体运动的二次角加速度表达式以及点做一般运动时的二次加速度合成定理。文末给出了应用合成定理进行机构二次加速度分析的示例。
In this paper, the expressions of secend acceleration of moving point which has curvilinear motion and second angular accelclation of moving rigid body and the superposition theorem of second acceleration are presented by differential geometry. In the end, a example of using this superposition theorem for the analysis of mechanisms is given.
