摘要
对两种安装情况的双向联轴器，分别选择了６个动坐标和４个静坐标．导出用统一的广义坐标表示的各构件在任意位置的受力表达式，给出了各构件在一个运动周期中的受力变化曲线，揭示了各构件受力后的应力循环特征。
in this paper, six moving coordinate systems and four fixed coodinate systems are selected respectively for double universal coupling under two different arrangement cases. For the first time, the applied force expression of any position of each linkin form of a universal generalized coordinate system is obtained, and the force variationof each link during a motion cycle is drawn, which reveals the stress cycling characterization of each link being exerted by force.
