Abstract

The invention provides a device for measuring the damping ratio of a damper, belonging to the technical field of space application equipment. The device comprises a measuring support, an rzeppa synchronizing universal coupling, a magnetic fluid sealing device, a coupling, a torque sensor, a loading device, a sensor support, a base, a temperature controller and an angle coder, wherein both the loading device and the sensor support are fixedly connected with the base; the torque sensor is connected with the loading device and the magnetic fluid sealing device; the rzeppa synchronizing universal coupling is connected with the measuring support; and the measurement data measured by the torque sensor and the angle coder is accessed to a PC (personal computer) machine via a data wire to acquire the measurement data. The device of the invention is capable of measuring the damping ratio of a damper assembly at minus100 to 70 DEG C and working stably within the vacuum, high-temperature or low-temperature environment; the device has the advantages of high measurement accuracy and high load matching performance; and the torque sensor has low temperature drifting.

Description

technical field [0001] A device for testing the damping rate of a damper according to the invention belongs to the technical field of space application equipment. Background technique [0002] At present, it is used in the solar wing deployment mechanism of stars and ships, and the deployment process of solar panels. It mainly relies on the energy stored in the coil springs of the root hinge and the inter-panel hinge to gather and release energy when unfolding to drive the solar panel to unfold. The speed of the board is uncontrollable; therefore, a damper device is added to the hinge at the root of the solar panel deployment to control the speed of the solar panel deployment. [0003] The damper damping rate testing equipment is used to test the damper at different speeds corresponding to different loading torques, and calculate the damping rate. In order to realize the quality control of the damper, it is necessary to use a combined test method to conduct high and low tem...
