By analyzing the relations of two adjacent waves in the process of locomotion and doing an approximation of the serpenoid curve, the motion function of relative angles between two adjacent links and the absolute angles between each link and the baseline on the traveling curve are built.

通过对蠕动运动过程中相邻2个波形的分析和对serpenoid曲线的近似，建立了运动波形上各相邻连杆间的相对角度运动方程和各连杆与基线之间的绝对角度运动方程。

The gait model is suitable for different inchworm locomotions of a snakelike robot whose traveling waves are formed by different numbers of identical links.

该步态模型可适用于运动波形由不同连杆数组成的蛇形机器人的蠕动，波形连杆较多或连杆夹角较大均可获得较大的运动速度。

The piston is attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.the bottom of the connecting rod is attached to the crankshaft.the connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.the connecting rod is mounted on the crankshaft with large bearings called rod bearings.

这个活塞被一个叫活塞销或轴颈销的销子连接在连杆的上部。连杆的底部被连接在曲轴上。连杆把活塞的上下运动传递给曲轴转变成旋转运动。连杆通过一个大的叫做杆轴承的轴承（其实就是滑动轴承，分成两个半圆轴瓦）安装在曲轴上。

The small end of connecting rod acts to-and-fro movement, and the big end of acts circumvolve movement. The connecting rod body acts complex plane movement. The connecting rod is one of the accessories that endures heavy load. And at the same time it endures gas pressure transmitted from the piston, the to-and-fro inertia force and inertia force engendered when itself swings.

连杆工作的小端作往复运动，大端作旋转运动，杆身做复杂的平面运动，连杆是承受负荷最严重的零件之一，同时承受着活塞传来的气体压力、往复惯性力和它本身摆动时所产生的惯性力的作用，这些力的大小和方向周期性变化，易引起连杆疲劳破坏。
