Description

technical field [0001] The invention belongs to friction and wear testing equipment, in particular to a rope ultra-high-speed friction testing machine. Background technique [0002] The friction and wear test bench is an experimental device for testing the friction and wear characteristics of the matching pair. The rope ultra-high-speed friction test bench is mainly used to test the sliding friction and wear characteristics of ropes under different materials, loads and wrap angles. In practical applications, such as ship cables, elevator traction cables, etc., the use of ropes is accompanied by wear and tear with other parts. As the degree of wear increases, the safety and stability of the ropes will be affected to a certain extent. Influence, and then affect the use of the corresponding equipment, resulting in unnecessary losses, which requires testing and analysis of the friction and wear properties of the rope. Therefore, a rope sliding contact friction and wear testing...
