Embodiment Construction

[0032] The satellite dynamic and static balance test and adjustment device and method thereof of the present invention firstly solve the problem of unifying the three axes, and secondly use the moment-force couple balance technology for measurement and adjustment. "The moment-couple balance method, the process is: first use the moment measurement method to balance and solve the center of mass deviation of the satellite, so that the center of mass deviation can be controlled within a suitable range; then use the two-plane force couple balance method to adjust the satellite's couple balance Adjust the unbalanced amount to make its deflection angle deviation accuracy within the range of technical requirements; finally use the three-plane method to measure.

[0033] The first solution of the present invention, the embodiment of the satellite dynamic and static balance test and adjustment device will be further described in detail below in conjunction with the accompanying drawings....

Abstract

The invention discloses a satellite dynamic and static balance test and adjustment device, comprising: a satellite body to be tested is fixed on a satellite connection disc. The satellite connecting disk is connected with the plane of the connecting disk of the dynamic balancing machine, and is fixed with positioning pins to form a transitional tooling. The transition tooling can move horizontally in X and Y directions on the dynamic balancing machine. The connecting disc of the dynamic balancing machine is fixed on the plane of the dynamic balancing machine with connecting bolts, and there is an adjusting gasket in the middle. A fixed support is installed on one side of the planar main table of the dynamic balancing machine, and an adjusting screw is arranged on it. The invention also discloses the test and adjustment method of the dynamic and static balance test and adjustment device, adopts the technical scheme of "torque-couple balance method", and achieves the problem of completing the satellite dynamic and static balance test and adjustment at one time, which not only improves the efficiency of test and adjustment Accuracy, and the adjustment time is reduced from 7 days to 2 days.

Description

technical field [0001] The invention relates to the test and adjustment of the dynamic balance and the static balance of an object. More specifically, the invention relates to a space satellite dynamic and static balance test and adjustment device. The invention also relates to a testing and adjusting method of the device. Background technique [0002] At present, the dynamic and static balance tests of space satellites can only be carried out individually at home and abroad. That is to do static balance (one-plane method) test and adjustment first, and then perform dynamic balance (two-plane method) test and adjustment after adjustment. According to this balancing process, the mass of the space satellite's counterweight is very large, and every increase of 1 kg in the mass of the space satellite's counterweight will increase the expensive launch cost. In order to reduce the quality of the counterweight, it is necessary to study and formulate a new dynamic and static bala...
