AI Technical Summary
Technical Problem
Existing tooling cannot accurately simulate the relative axial movement of O-rings, nor can it accurately record the frictional force between the sealed component and the O-ring.
Method used
A test fixture including a base plate, test pin, test body, adapter, and adapter rod is designed. It is connected to a reciprocating mobile device through the adapter to provide horizontal pressure, simulate the actual working conditions of O-ring seals, and measure friction force through a pressure sensor.
Benefits of technology
It improves the accuracy and reliability of O-ring friction testing, can simulate actual working conditions, adapts to the testing needs of O-rings of different specifications, and improves testing efficiency and reliability.
