Ultra-small high-power radar servo system closed-loop simulating load bench

Abstract

The invention provides an ultra-small high-power radar servo system closed-loop simulating load bench. The output end of a servo motor, the small gear of a reversing gear set, and an inertia disk group are installed coaxially. The large gear of the reversing gear set, a magnetic powder brake, a planetary reducer and the driving gear of a first anti-backlash gear set are installed coaxially. The anti-backlash gear of the first anti-backlash gear set and the driving gear of a second anti-backlash gear set are installed coaxially. The anti-backlash gear of the second anti-backlash gear set, an elastic coupling and the input end of a photoelectric encoder are installed coaxially. The ultra-small high-power radar servo system closed-loop simulating load bench can simulate the loads of various radar servo systems and high-power rotary tables, and greatly reduced in size and weight.

Description

technical field [0001] The invention relates to the field of servo control and is used for the simulation and debugging of various radar servo systems and high-power turntables. Background technique [0002] There are three types of torque and moment of inertia simulation methods for existing load simulators in China. One category uses friction discs and flywheels to simulate torque and moment of inertia. "Device" (patent application number: CN201710233740.3; publication number: CN106840646A), "a dual-station servo mechanism load simulator" invented by Beijing Institute of Mechanical Equipment (patent application number: CN201610946082.8; publication number: CN106297529A ) and the "Electric Servo Mechanism Load Simulation System and Its Simulation Method" invented by Beijing Jiaotong University (patent application number: CN201610771926.X; publication number: CN106323618A). Another type uses a speed increaser or spring, flywheel to simulate torque and moment of inertia, suc...

Problems solved by technology

The third category uses magnetic powder brakes and flywheels to simulate torque and moment of inertia. Although the use of magnetic powder brakes to simulate torque reduces part of the volume, the magnetic powder brakes and flywheels are placed on the load shaft. Although the weight and volume are slightly smaller than those of the first two types small but still big

[0003] It can be seen from the above that although the current domestic load simulation device can provide a platform for the debugging of the servo system and the turntable, since the moment loading mechanism, the inertia simulation mechanism and the sensor are all on the same load axis, the high-power radar servo system simulates the load platform. The volume and weight are very large, the power of the simulated load is limited, and it is not easy to move. The debugging place generally needs to be fixed; Seriously affect the development progress of the follow-up system, and also affect the development and debugging progress of the radar terminal
