Mass center adjustment system of air-floating motion simulator

Abstract

The invention relates to a mass center adjustment system of an air-floating motion simulator, which comprises a fixed counterweight unit, an adjustable counterweight unit, a first level gauge, a second level gauge and three gravity sensors, and is characterized in that the fixed counterweight unit comprises a plurality of counterweight blocks which are different in weight; the adjustable counterweight unit comprises a manual rough adjustment counterweight unit, a manual fine adjustment counterweight unit and an electrically controlled fine adjustment counterweight unit. According to the invention, under assistance of the first level gauge, the second level gauge and the three gravity sensors, mass centers of a translation platform and an attitude platform of the air-floating motion simulator can be gradually adjusted to a gyration center through three-level adjustment, that is, manual rough adjustment, manual fine adjustment and electrically controlled fine adjustment, of the fixed counterweight unit and the adjustable counterweight unit, thereby not only increasing the capacity and the range of mass center adjustment, but also improving the precision of mass center adjustment, greatly reducing the difficulty in mass center adjustment, and greatly shortening the time of mass center adjustment.

Description

technical field [0001] The invention relates to a center-of-mass adjustment system of an air-floating motion simulator, which belongs to the field of space vehicle semi-physical simulation. Background technique [0002] The air-floating motion simulator can be used to simulate the space attitude motion of spacecraft such as satellites, including attitude rotation motion and orbital translation motion. [0003] Domestic research on air flotation simulation test system started relatively late. my country's first-generation three-degree-of-freedom satellite air flotation simulation test system was developed by a domestic research institute in the late 1960s and has now been decommissioned. There are several major problems in the development of air-floating simulation simulators, one of which is the adjustment of the center of mass of the simulator body. Only when the center of mass of the simulator coincides completely with the geometric center can the simulator hover stably a...

AI Technical Summary

Problems solved by technology

[0004] The existing center of mass adjustment system is generally realized by manually adding counterweights, the adjustment ability is single, and there is external force interference in manual adjustment, and the adjustment accuracy is difficult to guarantee
