Mars gravity ground-based simulation device and simulation method thereof

Abstract

The invention relates to a Mars gravity ground-based simulation device and a simulation method thereof. The device and method which are provided by the invention are mainly used for simulating Mars gravity with both magnitude and direction changed in a simulated test, a gravitational field does not need to be produced on the whole test system, and only a motion simulator needs to be always under the action of the gravity in the whole testing stage. By virtue of coordination of equipment such as a gravity applying device and a position measuring device, Mars gravity action with both the magnitude and direction changed at the same time is simulated by a resultant force received by the motion simulator, and a practical process of orbit control is truly simulated. The device provided by the invention is simple in structure, the control method is simple and easy, and cost is low.

Description

technical field [0001] The invention relates to the field of electromagnetism, in particular to a Mars gravity simulation device and a simulation method based on the principle of electromagnetism for a ground half-physical simulation test of a Mars probe. Background technique [0002] Compared with other planets, Mars is the most similar to the earth, and it is also the planet most likely to find life beyond the earth. In recent years, some countries have launched Mars probes and launched Mars exploration research programs. An important mission of the mission is to detect the Martian surface, water and life. Before the launch of the Mars rover, a series of ground simulation tests are required. After the Mars rover enters the gravitational field of Mars, it enters a large elliptical orbit around Mars. To detect the surface of Mars, the rover needs to complete Mars capture and braking. The braking opportunity Only once, under the action of high thrust and the gravity of Mars,...

Problems solved by technology

[0006] Using the centrifuge method has great limitations: the test piece is installed at the end of the arm, and the Mars capture brake and device separation test needs to simulate the orbit and attitude changes of the Mars rover during this process, which cannot be completed by the centrifuge; the permanent magnet method: only The space magnetic field of the permanent magnet can be estimated according to the theoretical value. There will be a large error between the actual value and the theoretical value. additional impact
