Abstract

The invention relates to a device for testing a dynamic friction coefficient. The device comprises a fixed frame, a worktable, a tensile testing machine and a sample, wherein the sample comprises a fixed part and a movable part, a round drum mechanism for being wound with the fixed part is arranged on the fixed frame, a compression assembly is arranged on the round drum mechanism, a weight connected with one end of the movable part is arranged on the fixed frame, and the other end of the movable part is connected with the tensile testing machine. The device has the advantages that the round drum mechanism is wound with the fixed part in the sample, the movable part is pulled to move in the fixed part through the tensile testing machine, and the dynamic friction coefficient between the movable part and the fixed part is calculated according to an average tensile load measured in a tensile testing process, the gravity of the weight connected to one end of the movable part and the windingangle of the fixed part on the round drum mechanism, and the dynamic friction coefficient among samples can be accurately calculated; and the working intensity is low, the reliability of a sample testing result is good, and the sample testing efficiency can be increased.

Description

technical field [0001] The invention relates to a device for testing dynamic friction coefficient. Background technique [0002] The coefficient of friction is one of the basic properties of various materials. When there is relative motion or relative motion tendency between two objects in contact with each other, the mechanical force that hinders the relative motion generated on the contact surface is friction force. When the test light / cable slides on the inner wall of the silicon core tube, the dynamic friction coefficient between the outer surface of the light / cable and the inner surface of the silicon core tube is manually detected, resulting in the shortcomings of high intensity of detection work, low detection efficiency, and unstable detection quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for testing the dynamic friction coefficient, which solves the technical problem of high work inte...
