一、前言在用图解法求得机构的速度瞬心位置的基础上,仅能作机构的速度分析,当需要对机构进行加速度分析时,利用速度瞬心则是无能为力。本文是用解析法求得速度瞬心位置的基础上,不仅解决了机构的速度分析,而且开辟了用速度瞬心作加速度分析的力法。二、用速度瞬心求机构的加速度利用速度瞬心(以下简称瞬心)作机构的加速度分析,其步骤是: (1)求瞬心位置:建立瞬心位置的解析式;
First, the foreword In the graphical method of obtaining the body’s instantaneous center of the heart rate, based only on the speed of institutions for the analysis, when the need for acceleration analysis of institutions, the use of instantaneous center of speed is powerless. This paper is based on the analytic method to find the instantaneous center of the velocity, which not only solves the velocity analysis of the mechanism, but also opens up the force method of using the instantaneous center of acceleration for acceleration analysis. Second, with the speed of the center of the body to seek instantaneous acceleration The use of instantaneous center of speed (hereinafter referred to as instantaneous center) for the agency’s acceleration analysis, the steps are: (1) find the instantaneous center position:
