Complex Number Method for Kinematic Analysis of Air-Hydro Linkage and Its CAD

本文采用复数的指数形式表示机构的位置方程式,然后对时间求一、二次导数,求得变长度连杆的运动参数,R_2,_2,_2,O_2,_2,_2;再根据两构件重合点相对运动原理,求得其上点 C_2的运动参数_(Vc2),_(c2.给定步长ΔO_1在 IBM-PC 上求得一个运动循环的运动参数.

By using exponential form of complex number to stand a position equation of linkage.By applying first and second berivative of vector position equation with respect to time,it obtains kinematic parameters R_2,_2,_2,O_2,_2,_2, of a varying length bar. Based on the principle of relative motion at the duplication point of two members,it establishes kinematic parameters V_(c2)and a_(c2)at point C_2 on a va- rying length bar. To be done on an IBM-PC in a step ΔO_1,and it obtains kinematic parameters in a motive circle.
