Abstract

The invention belongs to the field of a servo mechanism, relates to an adjustable-rigidity double-air-rudder equivalent load simulation device, and specifically relates to an adjustable-rigidity double-air-rudder equivalent load simulation device for acceptance inspection of electro-hydraulic servo mechanism. The device comprises a right-end inertia assembly, a left-end inertia assembly, a base and an elastic support ear assembly; and the right-end inertia assembly and the left-end inertia assembly are symmetrically fixed on the base, and the elastic support ear assembly is fixed to a side face of the base. The device has the advantages of two-position integration and the small space structure, a load characteristic is guaranteed to be stable and reliable in a long term, and assembly and disassembly of a to-be-detected product, filling of a servo mechanism, vacuum pumping and other operation are convenient to perform; the rotational inertia, the inertia moment and the load rigidity parameter are adjustable; and, when the device does not work, a swinging scope of a rocker arm can be limited through a limited rod, and then the object of protection of n angle displacement sensor is achieved.

Description

technical field [0001] The invention belongs to the field of servo mechanisms, and in particular relates to a high-reliability equivalent load simulation device with adjustable stiffness double air rudders for acceptance of electro-hydraulic servo mechanisms. Background technique [0002] Servo mechanism is the collective name of the rocket control actuator subsystem in my country. Typical applications are thrust vector control of swing engines and air rudders. [0003] In order to meet the large-volume and long-term acceptance test tasks of the servo mechanism, and to solve the current situation that the tail section for the acceptance of the servo mechanism is compact in structure, the installation of the servo mechanism is difficult, which is not conducive to production acceptance, and the tail section for the acceptance inspection is used for a long time. After many high-frequency vibrations, the stiffness will change to varying degrees. Therefore, a simulated load devi...
