According to the servo mechanism load simulator, the structural characteristics, comprising the inertia load, the elastic moment load, the friction moment load and the supporting rigidity, of a rocket engine tail nozzle can be simulated; the elastic moment and the friction moment can be respectively measured through a torque sensor. The servo mechanism load simulator has the advantages of being simple and compact in structure and capable of enabling the structural characteristics of the actual rocket tail nozzle to well reappear.

Description
