Embodiment 1

[0025] Use the door bolt opening and closing mechanism testing device to test a single door bolt, and the preparatory work before the test includes passing the door bolt 6 to be tested in different processing technologies according to the actual working state through the pin seat 5 of the first simulated torso backpack and connecting it to the force sensor 4 through threads , and then load different loads by adjusting the axial position and spring compression of the knapsack pin seat 5 in the first simulated torso backpack pin seat; the first drive motor 2 rotates after the power is turned on during the official test, and the first crankshaft connecting rod slides The block combination 3 becomes a reciprocating linear motion, and the force sensor 4 fixedly connected with the first crankshaft-connecting rod slider combination 3 and the door bolt 6 to be tested also perform reciprocating motion at the same time. Evaluate whether the door bolt 6 to be tested meets the requirements...

Abstract

The invention relates to a simulation device for testing a locking mechanism of a complete set of extravehicular spacesuit, belonging to the technical field of aerospace. The simulation device comprises a latch opening and closing mechanism testing device, a driving mechanism testing device and a steel wire rope swing testing device. The device disclosed by the invention is a universal and reusable locking mechanism simulation test platform, which can be used for the theoretical research of the configuration of the locking mechanism on the one hand, can be used for the auxiliary engineering development on the other hand, and can timely evaluate and optimize the design scheme of the locking mechanism. The device disclosed by the invention is a test platform for simulating the configurationof the locking mechanism of the extravehicular spacesuit, can be used for the configuration design of the locking mechanism and the evaluation of a general scheme of project implementation, and can also be used for the study on an access structure composite system of the locking mechanism and the extravehicular spacesuit.

Description

technical field [0001] The invention relates to a simulation device for testing a locking mechanism of a complete set of extravehicular spacesuits, belonging to the field of aerospace technology. Background technique [0002] Extravehicular spacesuit equipment is the necessary support equipment for astronauts to go out of the cabin, and it can provide life support and ergonomic guarantee for astronauts in the extravehicular activities. In the current space suit equipment composition, the locking mechanism is an important part of the pressure suit, not only related to the ability to put on and take off the extravehicular spacesuit, but also has an important impact on ensuring the safety of the extravehicular spacesuit. [0003] The core of the locking mechanism of the extravehicular spacesuit is a kinematic pair composed of several sets of identical door bolts, cotter pin seats and guide pin seats. Clearance fit, which plays a guiding role when the latch performs linear reci...
