In this paper, we develop a durability test method that can verify the noise caused by the repeated load on the door trim grip handle. The test method was developed in consideration of the load mode and durability test cycle applied to the grip handle. In order to verify the validity of the method, we demonstrated the door trim grip handle noise that occurred in the field claim with the product in the early stage of mass production through the developed test method. Finally, It is used to detect and improve the noise of subsequent development products through the currently developed test method.
