It shows that the elastic modulus and the molecular component of friction coefficient of the pulley material have great influence on the wear resistance of wire rope.
The finite element analysis of the wheel rail contact shows that the maximum stress under the subsurface exceeds first yield strength, which leads to plastic deformation.

之后驱动臂通过弹簧拉动返回初始位置,此时驱动臂下面的小轮是滚动返回的,不产生相反的摩擦力。
The process is just like rowing a boat. And then, the driving arm return to the primary position by the pulling from the spring.
