Piezoelectric-driven force and displacement integrated high-precision test platform and method

The invention provides a piezoelectric-driven force and displacement integrated high-precision test platform and method. The piezoelectric-driven force and displacement integrated high-precision test platform is characterized in that two ends of a top clamping beam 1 are fixedly connected with piezoelectric thread linear motors 5 respectively; the sensor 2 penetrates through the top clamping beam 1 and is in contact measurement with the linear actuator 4; the measurement pose is adjusted through synchronous up-down high-precision movement of the piezoelectric thread linear motor 5; the linear actuator 4 is placed on the centering clamping mechanism 7, and the centering clamping mechanism 7 is connected with the guide rail; the guide rail is connected with the piezoelectric rotating motor 10 and is fixed on the bottom adapter plate 14; a piezoelectric rotating motor 10 drives a connecting rod to drive a guide rail so as to drive a middle clamping mechanism 7, and centering and clamping of a linear actuator 4 a
