Abstract

The present invention discloses a high-pressure pneumatic gravity balance type space motion simulator. It is composed of parallelly-connected six-freedom motion platform, simulation chamber, heaving movement platform and safety protective system. On the intermediate platform of heaving movement platform system the parallelly-connected six-fredom motion platform is mounted, and a gravity balance device formed from driven hydraulic cylinder and cylinder and matched pneumatic system is vertically mounted in the central lower portion of the intermediate platform, and on the two ends of intermediate platform and its one side surface the guideway slide blocks are mounted, and matched with the guideways on the peripheral three walls of the motion simulator. It is safe, reliable and low in power consumptio, can implement six-freedom motion and heaving movement.

Description

Technical field [0001] The invention relates to a motion simulator, in particular to a high-pressure pneumatic gravity balance space motion simulator. Background technique [0002] With the development of ground simulation technology, many foreign air, space and ocean tests and trainings are carried out on the ground. The ground test is safe and saves money. my country is also vigorously developing ground simulation technology, but it still lags behind developed countries in Europe and the United States in terms of quantity and technical level. There is a lot of room for development, and rapid development is urgently needed. [0003] The movement of ships and aircraft is multi-attitude three-dimensional space movement, and the motion simulator can describe it more accurately and perform dynamic simulation on its movement state. [0004] Domestically, Stewart structures are mostly used in motion simulator platforms with small and medium motion amplitudes to realize six-degre...
