画法几何在空间机构定位问题上的应用

Descriptive geometry in the position of the space agencies

在进行机构运动分析中,常需要确定机构中杆件的位置、速度和加速度等问题,若用数学分析法,计算往往十分复杂,甚至容易出错;采用画法几何图解法,解题速度快,概念清晰,在一定程度范围内有它的应用价值。

Due to the carrying out of the kinematic analysis,often need to determine the rod position,velocity and acceleration in the organization,if using mathematical analysis,the calculation is often very complex,and even prone to errors;but use of descriptive geometry graphic method,problem-solving speed and the concept is clear,the value of its application to a certain extent within.
