Abstract

The invention relates to the technical field of electro-mechanical servo control and implements a bending-torsion combination two-dimensional time-varying load loading device and relates to two-dimensional combination load applying device taking torque loading and bending moment loading as the core. The actuating mechanism of the bending-torsion combination two-dimensional time-varying load loading device mainly comprises: a to-be-loaded object module 01, a torque loading module 02, a bending moment loading module 03, a plane bearing module 04 and a variable bending moment loading point module 05. The device is used for applying time-varying load to a tested actuating mechanism physically in real time. The device is mainly used for aerospace rudder-face actuator aerodynamic load simulation, ship rudder-face and fin stabilizer actuator loading and vehicle motor and transmission load simulation. The most remarkable characteristic of the device is synchronous application of bending-torsion two-dimensional time-varying loads. The device can realize the prior time-varying torque loading and synchronously apply time-varying bending moment load to a shaft of an object to be loaded; and an action spot of the bending moment is variable in real time.

Description

technical field [0001] The invention belongs to the technical field of electromechanical servo control, and relates to a bending-torsion combined two-dimensional time-varying load loading device. Background technique [0002] "Accuracy" is the core of the performance of modern aircraft, guided weapons and ships. The attitude and trajectory control of the equipment is the key. This process is completed by the aerodynamic and hydrodynamic adjustment of the rudder actuator. "Load Simulator" is an essential equipment for ground tests of aircraft and ships. It can accurately reproduce the final loaded working state of the rudder actuator by actively applying time-varying loads on the ground in real time, which is helpful for improving, enhancing and ensuring control accuracy. play an irreplaceable role. [0003] With the continuous improvement of the precision guidance requirements of aircraft and ships, the ground test of the airborne control system and the large closed-loop ha...
