A Landing Impact Simulation Test Method for Lunar Lander

Abstract The lunar lander shall be suffered transient impact load during the landing process. The structure’s ability of withstand the dynamic environment is the key to success of a soft landing. Therefore, it is necessary to conduct the simulation test of landing impact on the ground to examine and verify the structure of the lunar lander on the development stage of the lunar lander. This paper introduces the test system principle, composition and application design, and presents a method to simulate the landing surface material selection, of the design of lifting and releasing separation device, and the composition of measurement system. The test technique is both suitable for the verification test of the structure and the flight phase stage, and shall be carried out in a clean environment. The test method presented in this paper has been successfully applied in the Chang’e lunar landers.
