Abstract

A seal performance comprehensive testing device for a deep lunar soil seal assembly relates to a seal performance comprehensive testing device. At present, there is no special seal assembly performance testing device, thus bringing inconvenience for smooth collection and research of deep lunar soil. Therefore, in order to solve the above problem, the invention provides the seal performance comprehensive testing device. The device provided by the invention comprises a seal environmental simulation module (A), a seal force application and test module (B) and a seal collapsing force application and test module (C). The seal force application and test module (B) and the seal collapsing force application and test module (C) are both arranged on the seal environmental simulation module (A). Quantitative application and real-time monitoring of normal closing force are realized through the seal force application and test module. Collapsing force required by destruction of a seal and changes of the collapsing force during the seal destroying process are measured by the seal collapsing force application and test module. The seal performance comprehensive testing device provided by the invention is suitable for testing of the deep lunar soil seal assembly.

Description

technical field [0001] The invention relates to a comprehensive testing device for sealing performance, in particular to a comprehensive testing device for sealing performance used for deep lunar soil sealing components. Background technique [0002] Aerospace technology is a cutting-edge project for human exploration of the natural world. Going into space has become an indispensable symbol of a powerful country in science and technology. Every link in the aerospace system is very important. How to collect the lunar surface through an unmanned automatic sampling device on the lunar surface with low gravity The deep lunar soil below is a major technical problem. [0003] In order to adapt the deep lunar soil sampling device to the requirements of space exploration, the deep lunar soil samples are encapsulated by the non-slip soft bag coring method. This coring method has the advantages of high coring rate, low coring force, and strong bedding information retention. In additi...
