Device and method for measuring contact load of moving object

The invention relates to a device and method for measuring the contact load of a moving object, and the device comprises a piston rod, one end of the piston rod is provided with a piston, the piston and the piston rod extend into a sleeve with an opening at one end, the periphery of the piston is in contact fit with the inner wall of the sleeve, and the piston is connected with the piston rod through a sliding load measurement device. A fixed load measuring device is installed on the end face of the opening of the sleeve, the sliding load measuring device measures the contact force of the piston and the piston rod in the sliding motion, and the fixed load measuring device measures the contact force of the piston rod and the end face of the opening of the sleeve in the relative motion process. Therefore, dynamic measurement of the contact load of the workpiece in the movement process is achieved, the mechanical environment of the workpiece in the actual operation process is accurately sensed, the refinement de
