摘要
除基点法外 ,还可延伸出投影法及瞬心法分析平面运动刚体各点的加速度。本文在投影法所用公式的基础上 ,论证了加速度分析须给定四个独立条件 ,分析出任意两点加速度方向可能出现的各种情况 ;研究了在各种给定条件情况下加速度瞬心位置的确定方法。
This paper introduces the formula of projective method in analysis of accelerations of all points in a planarly moving body. That the four conditions to be given is necessary is verified, and all kinds of possibility about acceleration's direction of two points are discussed. The method of specifying the place of instanteous centre of acceleration in any given conditions are studied.
