Lander falling weight impact test device with adjustable angles

Abstract

The invention discloses a lander falling weight impact test device with adjustable angles. The lander falling weight impact test device with the adjustable angles is composed of a rack, a lifting device, an oil cylinder, a releasing device, weight-balancing weights, a hammer carrier, a guide rail, a buffer leg angle adjustment device, buffer legs, foot pads, a soil box, a cutting board and a data acquisition system. According to the lander falling weight impact test device with the adjustable angles, different impact rates are realized through control over height; the impact energy is controlled through the weight-balancing weights, and screws are used for limiting so that the buffer legs and the foot pads can impact simulated lunar soil at different angles; aluminum pipes with different diameters are used as buffer materials, so that the lander impact test conditions are reflected authentically; the dynamic characteristics of the interaction between the foot pads and the simulated lunar soil in the impact process are obtained simply, conveniently and safely.

Description

technical field [0001] The invention relates to an angle-adjustable lander drop hammer impact test device, which can be used to measure the mechanical performance parameters of the lunar soil simulated by the impact of the foot pad of the lander. Background technique [0002] The research and development of lunar exploration is inseparable from the landing of the landing probe, and its own safety and stability are important guarantees to ensure the successful landing of the lander. During the landing process of the lander, considering the unevenness of the lunar surface and the navigation accuracy of the lander during the descent process, when the foot pads contact the lunar soil, they do not always contact the lunar soil vertically, so the lander’s foot pads and the lunar soil The mechanical properties of the interaction are the focus of experimental research. At present, there are many researches on the interaction between machinery and simulated lunar soil at home and ab...
