Abstract

The invention relates to an extravehicular spacesuit glove finger movement life span experiment device which comprises an air compressor, a vacuum generator, an air feeding hose, an extravehicular spacesuit glove, a finger suction disk, a driving cylinder component, a glove clamping mechanism, a three-finger suction disk clamping plate and a framework, wherein pressure air supplied by the air compressor is divided into two paths through the air feeding hose; one path is guided to the driving cylinder component to enable a driving cylinder to work, and the other path is guided to the vacuum generator, so that the vacuum generator generates vacuum degree, and generated negative pressure enables the finger suction disk to generate vacuum to firmly adsorb five fingers. According to the extravehicular spacesuit glove finger movement life span experiment device, finger movement of a person is simulated by a physical method, so that the extravehicular spacesuit glove finger movement life span experiment device replaces a hand to do life span test/experiment on extravehicular spacesuit glove fingers; therefore, the high-intensity life span test/experiment can be quickly implemented, and detection data can be acquired for technology research and application; finger tips of fingers of the extravehicular spacesuit glove are tightly connected with a test mechanism in a vacuum adsorption manner, so that the fingers cannot fall off, and no damage to the glove can be generated.

Description

technical field [0001] The invention relates to an experimental device, in particular to a device for performing experiments on the finger movement life of an extravehicular spacesuit glove. Background technique [0002] When using an external measuring device to measure the motion life of the glove fingers of an extravehicular space suit, it is necessary to connect the fingertips of the glove with the peripheral mechanism and clamp it tightly for testing. Because the shape of the fingertip of the finger is an arc surface, it is easy to fall off when the card is not tight, and it is easy to damage the glove if the card is too tight, and the clamping force is difficult to control. Therefore, the current test device has poor versatility, poor safety, and is easy to cause damage to the glove. Moreover, the test is difficult, labor-intensive to operate, and has low accuracy. It is labor-intensive and time-consuming to manually adjust and test space suit gloves of different type...
