Planet landing motion simulation system and method based on air-floating platform

Abstract

The invention discloses a planet landing motion simulation system and method based on an air-floating platform, wherein the system comprises of a three degree-of-freedom air flotation supporting subsystem, a single degree-of-freedom air flotation supporting subsystem, a motion assisting subsystem, an air flotation system main platform, a thrust executing subsystem, a pose measurement subsystem and a controller. According to the invention, the three degree-of-freedom air flotation supporting subsystem, the single degree-of-freedom air flotation supporting subsystem, the air flotation system main platform and the thrust executing subsystem are used for simulating the motion of a spacecraft in space, a force applying device with a given original state is used for driving the spacecraft to reach an original operation state, a gravitation simulating applied force device is used for simulating gravitation between the spacecraft and a planet. By using the planet landing motion simulation system and method, a complex deep-space environment can be simulated, full physical simulation of the planet landing motion is realized, the cost-effectiveness of an aircraft is improved, the risk is reduced, the development cycle is shortened, and the planet landing motion simulation system and method have significant meanings on deep space exploration, planet landing research and the like.

Description

technical field [0001] The invention relates to the technical field of spacecraft simulation, in particular to a planetary landing motion simulation system and method based on an air bearing platform. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Modern aerospace deep space exploration missions require planetary landing detection. It is a complex movement process for a spacecraft to enter the planetary atmosphere from orbiting until it lands on the planet. During this process, the lander needs to face the complex and changeable planetary environment and sudden conditions, and it is necessary to control the orbital attitude, whether the landing is successful or not is directly related to the success or failure of the detection mission. [0004] Once the spacecraft is launched, it will be difficult to maintain...
