Abstract

The invention relates to a device which is used for assisting solar cell wings, a mast and mechanical arms on a lunar vehicle in unfolding to carry out testing, and particularly discloses a device for simulating a microgravity environment on the lunar surface. The device for simulating the microgravity environment on the lunar surface comprises a moving mechanism, a framework, a servo mechanism, a hanging mechanism and a balance weight mechanism, wherein the low-gravity simulating device is formed by the moving mechanism, the framework, the servo mechanism, the hanging mechanism and the balance weight mechanism together. According to structural features and motion features of a lunar vehicle mechanism product, hanging tension is provided by a pulley system formed by movable pulleys and fixed pulleys and balance weight of weights, the 1 / 6g gravity of a tested product can be eliminated, or zero gravity of the tested product can be achieved, the movable pulleys slide on guide rail rods of the servo mechanism at the same time, and can carry out servo together with the tested product, and the 1 / 6g low-gravity environment or the zero gravity environment can be provided in the whole process. The device for simulating the microgravity environment on the lunar surface is convenient to move, can be rapidly disassembled, built and assembled, can be rapidly located in place and work, and is convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a device for assisting the deployment and testing of solar battery wings, masts and mechanical arms on a lunar rover, in particular to a device for simulating the microgravity environment on the lunar surface. Background technique [0002] At present, there are many methods for simulating gravity compensation on the ground, mainly including drop method, parabolic flight method, buoyancy method, air cushion method, suspension method, etc. Defects such as stability, inaccurate microgravity, and space limitations cannot be applied to the environmental tests of the lunar rover. [0003] Suspension method is a commonly used method in aerospace agencies. It is mainly to apply a concentrated force through its center of mass to the test object on the ground through the suspension system to partially offset gravity, and it can accurately offset part of gravity. Provides a constant tension in the vertical direction. However, the tradit...
