Method for adaptively adjusting load fluctuation of motor-driven scratch tester by compliant mechanism

The invention relates to the technical field of material surface performance testing, in particular to a method for adaptively adjusting load fluctuation of a motor-driven scratch tester through a compliant mechanism. In the scratch test process of a motor-driven scratch tester, due to the fact that a micron-order axial transmission gap exists in a ball screw and sub-second-order response time exists in a motor, compensation of axial force can be greatly influenced, and then large fluctuation of axial loads is caused, and the problem generally exists in the motor-driven scratch tester. In order to solve the technical problem, the invention provides the method for adaptively adjusting the load fluctuation of the motor-driven scratch tester through the compliant mechanism, in a scratch test, the compliant mechanism can immediately make load compensation according to the elastic deformation of the compliant mechanism, the adaptive effect is achieved, the problem of axial load compensation delay is solved, and th
