Abstract

Based on an introduction to the structure and working principle of composite force loading system

the relation between composite force and branch chain forces was deduced

and a mathematical model of one branch chain force loading system was established to analyze its stability.The simulation and experiment lead to a conclusion that damp and noise of force are main factors which have a serious effect on the stability and response speed.A new control algorithm was proposed

and the experimental results show that the algorithm improves the performance of the system significantly.The frequency of combined moment and axial force loading can reach 10Hz by using this control method.
