Abstract

The paper selects 22# locating detent in the JYH extravehicular connector as the research object, builds a force model for locating detent in the connector, and conducts force analysis for shortening problem due to locating detent. Through conducting force calculation and ANSYS simulation for clamping the jaw of the locating detent, the paper provides the failure mechanism of the locating detent under overload. Besides, the paper prepares a failure test for locating detent under overload and deploys the test. By analyzing deformation quantity and microscopic fracture morphology of locating detent, the paper verifies the failure mechanism and determines the validity of the failure mode of locating detent under overload.
