Description

technical field [0001] The invention belongs to the field of stiffness testing, and in particular relates to a stiffness testing device for an electromechanical servo mechanism, in particular to a device capable of testing the comprehensive stiffness of an electromechanical servo mechanism including torsion, tension and compression. Background technique [0002] As the most important and complex link in the servo loop, the electromechanical servo mechanism is the main optimization target of the dynamic characteristics of the servo system, and its mechanical characteristics such as stiffness and clearance are the most important parameters in the performance simulation model of the electromechanical servo system. The reliability greatly affects the accuracy of the results of the system performance simulation model. The electromechanical servo mechanism has problems such as complex structure and many transmission links. It is usually difficult to accurately calculate the stiffn...
