Problems solved by technology

[0003] Most of the traditional torque loading equipment for servo mechanisms are pendulum-type structures, that is, the simulation of inertial loads adopts eccentric pendulum-type structures. This kind of eccentric load simulator will appear overall larger during the frequency sweep test of servo mechanisms. Vibration will have adverse effects on the surrounding test environment, and the inertia adjustment method is not very convenient
In addition, the previous servo mechanism load simulator did not consider the elastic moment loading enough

Abstract

The invention discloses a servo mechanism force moment loading device and belongs to the technical field of mechanical system test facilities. The friction moment loading of the device can be continuously adjusted by loading hydraulic oil, and meanwhile a loading moment can be monitored through a friction moment sensor in real time; elastic moment loading can be continuously adjusted, a supporting spring plate is used for achieving the supporting rigidity of a servo mechanism for overcoming the strength requirement of a spring moment spring plate, and continuous supporting rigidity adjustment can be achieved by adjusting the clamping position of the supporting spring plate. The servo mechanism force moment loading device has the advantages that compared with a traditional servo mechanism force moment loading device, the friction moment loading of the device can be continuously adjusted by loading the hydraulic oil.

Description

technical field [0001] The invention relates to a torque loading device for a servo mechanism, specifically composed of an elastic torque device, a friction torque loading device, an inertia simulation disk, a support stiffness simulation device, and a load torque display device. The invention relates to the technical field of mechanical system test facilities. Background technique [0002] The torque loading device of the servo mechanism 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 rocket are getting higher and higher, which in turn puts forward higher requirements for the ground test of the servo mechanism, which promotes the research of the servo mechanism load simulator progress. [0003] Most of the traditional torque loading equipment for servo mecha...
