Problems solved by technology

However, this device involves linear motion and planar motion, and cannot be directly applied to the life test of shoulder joints and elbow joints of the upper limbs of extravehicular space suits.
[0006] Therefore, the current testing devices generally have defects of poor versatility, and the safety needs to be improved urgently, and the

Abstract

The invention provides a joint movement life testing device for an extravehicular space suit. The device comprises a stand, a driving unit and a rotary part, wherein the driving unit is arranged on the stand; the stand is connected with upper limbs of the space suit; the upper limbs of the space suit are connected with the rotary part by a flange unit; and the rotary part is connected with the driving unit. According to the joint movement life testing device, the upper limb movement of a person is simulated by a physical method, so that the life cycle of the upper limbs of the extravehicular space suit can be rapidly tested.

Description

technical field [0001] The invention relates to a life experiment device for an extravehicular spacesuit, in particular to a joint motion life test device for an extravehicular spacesuit. Background technique [0002] The extravehicular spacesuit is the most important life protection equipment for astronauts in extravehicular activities. During the service life of the space suit, the upper limbs of the space suit, including the two important parts of the shoulder joint and the elbow joint, are made of multi-layer fabrics with folded or flat pleated corrugated structures to make them bendable. At the same time, bearings are set near the elbow joints. Provides degrees of freedom for angular rotation. While ensuring the degree of freedom, it is also necessary to achieve sealing through the fabric. Therefore, the activities of the arm part often cause the upper limb to be bent many times, resulting in material fatigue and eventually causing air leakage and failure. Therefore,...
