用数值法研究油缸与摆臂干涉问题

Interference between swing lever and cylinder using numerical method

以静止坐标系为纽带,利用矩阵工具建立了相关两动坐标系之间的变换关系,实现了从一个动坐标系——摆臂坐标系上观测另外动坐标系——油缸坐标系内任意点的运动规律.用数值法预先判定油缸外轮廓以及关键点在摆臂刚体上的运动范围,为解决摆动油缸机构运动干涉建立了一种便捷方法,并用这一方法分析了一个典型的摆动油缸机构的运动干涉.

Based on the static coordinate system,the transform relationship between two moving coordinates is established via matrices.In this regard,the motional principles for one moving coordinate of cylinder can be speculated through the other moving coordinate of swing lever.Specifically in this study,the cylinder contour and relevant enabling points are pre-determined using numerical method within the motional range on swing lever rigid-body.Subsequently,the kinematical interference of swing lever mechanism is e...
