115 caprine right femurs were taken and created to simulate AO/33-A3 fracture. All fracture models were fixed by the right 5 hole LISS Plate, which treated differently by using unicortical or bicortical screws in the proximal end of the LISS plate. And then withdrawal force and torsional force were given on them to make comparison.

Thirdly , a conclusion has been settled down in this dissertation: Because the shaft inertial force vector do not pass the center of the rotating center of the system, there is a moment generated by the shaft inertial force and the counterforce of the cylinder wall to counterbalance the pressure which is imposed by the piston, so, it is important to consider the tortile effect on the flexible supporting component of the balancing machine dedicated to motorcycle crank set, which is originated by the moment.

第三：得到了一个结论：在设计制作曲柄连杆机构动平衡测试装置时，必须考虑这一受力情况，即连杆在作平面运动时，其自身的惯性力与汽缸对活塞的反作用力二者之间形成的力偶将会对弹性支承元件产生扭矩的作用。
