With the aid of the formula for the rotation of a vector and constraint equations for the connectingrod, the rotation Angle and the coordinates of path points of the connectingrod can be obtained.
应用矢量旋转公式及连杆运动约束方程，我们可以求得连杆转角及连杆曲线上点的坐标值。

The connectingrod carries the power thrusts from the piston to the crankpin. At the same time, the rod is in eccentric motion.
连杆的作用是将活塞承受的压力传给连杆轴颈。同时，连杆做偏心运动。

The general ways for exciting vibration is acted by the stiff connecting-rod or the elastic connecting-rod, in turn, called directly exciting vibration or indirectly exciting vibration.
