Problems solved by technology

When carrying out the life test of the upper limbs of the extravehicular spacesuit, the bending joints are driven by external force to simulate the movement of the upper limbs of the human body. However, since there are no arms inside the upper limbs of the clothing, when th

Abstract

The invention provides an extravehicular spacesuit upper-limb joint service life testing device, which comprises a rack, a driving mechanism and a fixing mechanism, wherein the driving mechanism and the fixing mechanism are arranged at a bottom plate of the rack; and the driving mechanism comprises a shoulder driving mechanism and an elbow driving mechanism, the fixing mechanism is arranged at the center of the bottom plate of the rack, and the shoulder driving mechanism and the elbow driving mechanism are arranged at two sides of the fixing mechanism respectively. An extravehicular spacesuit upper limb is installed on the fixing mechanism, and the extravehicular spacesuit upper limb is internally provided with a joint arm. Through the joint arm arranged inside the spacesuit upper limb, the torque is transmitted to the spacesuit upper limb through the built-in arm for a spacesuit, thereby more conforming to using characteristics of the spacesuit, and thus enabling a service life testing result of the spacesuit to be closer to real situations.

Description

technical field [0001] The invention relates to the technical field of detection of space suits, in particular to a life test device for upper limb joints of extravehicular space suits. Background technique [0002] As the most important life protection equipment for astronauts in extravehicular activities, the basic form of failure of the extravehicular spacesuit during its use is "the arm's movement causes the upper limb to bend, and repeated bending causes material fatigue, and the material fatigue reaches To a certain extent, it will eventually cause an air leak." Therefore, for the development of space suits, it is particularly important to know in advance the life of the bending-related parts of the upper limbs of the space suit. [0003] The more reliable method commonly used in current research is to obtain data that can characterize its lifespan through experimental methods. Since the activity life of the upper limbs of the spacesuit is at the level of hundreds of...
