Torque servo control loading load simulator

Abstract

A torque servo control loading load simulator comprises a base, a guide strip, a supporting spring plate base, a supporting spring plate, a supporting spring plate cover plate, a lower supporting lug, a side vertical plate, a motor mounting seat, a photoelectric encoder mounting seat, a swing hydraulic motor, a valve block, a servo valve, a rolling bearing, a loading torque sensor, a photoelectric encoder, a probe, a ball bearing, an upper supporting lug, an inertia counterweight disk, an inertia base disk, a spindle, an elastic torque mounting support, an elastic torque sensor, an elastic torque rotating shaft, a swing shifting fork, an elastic torque loading support, an elastic torque spring plate and a spring torque spring plate clamping plate. The torque servo control loading load simulator can simulate the structural characteristics of a rocket exhaust nozzle, wherein the structural characteristics comprise inertia loads, elastic torque loads, set torque loads and supporting stiffness. The torque servo control loading load simulator has the advantages of being simple and compact in structure, flexible in servo loading torque, high in precision, and capable of better reproducing the structural characteristics of the actual rocket exhaust nozzle.

Description

technical field [0001] The invention relates to a moment servo control loading load simulator, which is used for simulating mechanical characteristics of rocket tail nozzle mechanical structure. The device realizes the loading of inertia moment, elastic moment and support stiffness through mechanical means; the servo valve controls the swing hydraulic motor to realize the loading of set torque, and the torque loading realized by mechanical means can be continuously adjusted within a certain range. It is used to meet the needs of different torque loading. The loading of the set torque can be a function torque or a torque in the form of an arbitrary curve. At the same time, the set torque and the elastic moment can also be measured in real time through the torque sensor, which belongs to the electromechanical hydraulic control system test facility technology field. Background technique [0002] The torque servo control loading load simulator is a device used to simulate the s...
