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...
