Method for automatically testing steady state loss torque of flywheel

Abstract

The invention discloses a method for automatically testing the steady state loss torque of a flywheel, relating to a testing method of the steady state loss torque of a flywheel, and solving the problems that the steady state loss torque of the flywheel has larger error because the rotation speed of the flywheel is manually controlled in the traditional flywheel steady state loss torque test, andthe flywheel can not simulate a real attitude of satellite because the flywheel rotates in a rotation speed mode. The method for automatically testing the steady state loss torque of the flywheel comprises the steps of: firstly, controlling a computer to set an output torque, regulating the self rotation speed of the flywheel to reach the preset target rotation speed; secondly, controlling the computer to transmit a zero torque command to the flywheel, wherein the flywheel loses the torque and continuously rotates under the action of inertia; and thirdly, controlling the computer to obey a loss torque test algorithm, and regulating the flywheel to apply a torque to obtain the steady state loss torque of the flywheel. The invention realizes the automatic test of the steady state loss torque of the flywheel and is used for the steady state loss torque test of the flywheel.

Description

technical field [0001] The invention relates to a test method for the steady-state loss torque of a flywheel, in particular to a test method for realizing the automatic steady-state loss torque of the flywheel. Background technique [0002] The ground test process of the satellite includes component test, subsystem test and whole star test. In the component testing process, each component needs to be tested individually, and traditional component testing relies on manual implementation. In the test of the flywheel, it is necessary to test the steady loss torque of the flywheel. In this field, the flywheel steady-state loss torque refers to: when the flywheel is maintained at a specific speed, the torque required to maintain this speed is consumed. To test the steady loss torque of the flywheel, it is required to measure the torque when the flywheel is maintained at different speeds or even saturated speeds, and multiple tests are required to observe whether the previous t...
