Abstract

A servo mechanism load simulator comprises a base, side upright plates, elastic moment spring plate clamping boards, an elastic moment loading support, an elastic moment spring plate, a swing shifting fork, an elastic moment rotary shaft, an elastic moment sensor, ball bearings, a bearing cap, a bearing seat, a friction shaft, a small oil cylinder seat, friction moment loading small oil cylinders, friction sheets, a friction moment sensor, an installation seat, roller bearings, a main shaft, an inertia basic disc, an inertia balance weight disc, self-aligning roller bearings, an upper supporting lug, a supporting spring plate cover plate, a supporting spring plate base, a supporting spring plate, a lower supporting lug, a guide bar and a servo mechanism to be measured. 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

technical field [0001] The invention relates to a servomechanism load simulator, which is used for simulating the mechanical characteristics of the mechanical structure of a rocket tail nozzle. The device can realize the loading of moment of inertia, loading of elastic moment, support stiffness, loading of friction moment, and continuous adjustment of the above moments within a certain range to meet the needs of different moment loading. At the same time, the friction moment and elastic moment can also be Real-time measurement is carried out respectively through torque sensors, belonging to the technical field of mechanical system test facilities. Background technique [0002] The servomechanism load simulator is a device used to simulate the structural characteristics of the rocket tail nozzle in the ground laboratory environment. With the development of science and technology, the requirements for the large carrying capacity, maneuverability and control precision of the r...
