A lunar take-off initial attitude simulation device

Abstract

A lunar surface take-off initial attitude simulating device comprises a platform (1), a main body supporting structure (2), an angle adjusting mechanism (3), a locking mechanism (4) and a drilling cylinder simulation device (5). The platform (1) is under a detector (6) to support the detector (6) and butt-jointed with the detector (6). The main body supporting structure (2) is positioned under theplatform (1) and connected with the platform (1) through two groups of hinges. One end of the angle adjusting mechanism (3) is connected with the main body supporting structure (2); the other end ofthe angle adjusting mechanism (3) is connected with the platform (1); and through a hydraulic system, the angle adjusting mechanism (3) is driven to adjust an included angle between the platform (1) and the horizontal plane so as to realize requirements of an initial take-off attitude of the detector on an angle. The locking mechanism (4) is mounted under the platform (1). The drilling cylinder simulation device (5) is mounted above the platform (1). According to the lunar surface take-off initial attitude simulating device, the simulation of multiple lunar surface take-off attitude angles within a range of 0-25 degrees can be realized; the attitude angle adjusting accuracy is high; continuous adjusting can be realized; and the lunar surface take-off initial attitude simulating device canbe used for lunar surface sample return and detection.

Description

technical field [0001] The invention belongs to the field of spacecraft ground simulation test design, and relates to a lunar surface take-off initial attitude simulation device. Background technique [0002] Reliable and safe take-off from the lunar surface is the basic condition for the lunar probe to complete the lunar sample collection and return mission, and it is also a key technology for the development of the probe. It needs to carry out real and sufficient full physical verification tests on the ground. The take-off attitude of the probe on the lunar surface is its initial landing attitude, which is affected by the lunar surface terrain, landing parameters and the structure design of the probe. The attitude is a set of randomly changing parameters. In the ground verification test of the landing and take-off of the lunar probe, although the take-off attitude can be directly obtained by relying on the real landing link, this method is difficult to simulate the extreme...

Problems solved by technology

In the ground verification test of the landing and take-off of the lunar probe, although the take-off attitude can be directly obtained by relying on the real landing link, this method is difficult to simulate the extreme take-off conditions, and the randomness of the simulation parameters cannot be used to accurately determine the design boundary of the probe.
