本文通过微机的动态显示解决了相对轨迹难琢磨不易想象的难点,可以见到相对轨迹生成的全过程。通过改变运动学参数可以方便地探讨轨迹的形成规律,这对研究复合运动中动点、动系的选择,理解好相对轨迹提供了一种有效的方法。文章结尾给出了自编的程序。 This article through the dynamic display of the computer to solve the relative difficult to ponder the difficult to imagine difficult, you can see the relative trajectory generated by the whole process. By changing the kinematic parameters, the rule of trajectory formation can be conveniently explored. This provides an effective method for studying the choice of moving points and moving systems in compound motion and understanding relative trajectories. The end of the article gives a self-compiled program.
