The invention discloses an experimental device for testing rubber friction performance. The experimental device comprises two sliding rails, a sliding box, a pressure sensor, a tension sensor, a driving part and a linear displacement sensor, wherein the two sliding rails respectively extend along the longitudinal direction; the sliding box is slidably arranged on the two sliding rails by virtue of multiple slide blocks; a replaceable simulation road is arranged in the sliding box; the pressure sensor can move up and down and is arranged above the sliding box, and a to-be-detected rubber test sample is arranged on the bottom surface of the pressure sensor; the tension sensor is arranged at one longitudinal end of the sliding box; the driving part pulls the tension sensor and the sliding box to move along the longitudinal direction by virtue of a digging rope; and the linear displacement sensor is connected to the other longitudinal end of the sliding box so as to measure the longitudinal displacement of the sliding box. According to the experimental device for testing rubber friction performance disclosed by the invention, the rubber friction force, different pavements, the contact area, the load, sliding speed and a pavement environment with impurities can be regularly tested, so that the rubber performance is effectively researched.
Description
technical field [0001] The invention relates to the field of mechanical performance testing experimental devices, in particular to an experimental device for testing rubber friction properties. Background technique [0002] Rubber friction is a very complex problem, which is affected by factors such as rubber material properties, temperature, pressure, sliding speed, and contact interface, and is the result of the coupling of various influencing factors. Tires are an important product that embodies the friction characteristics of rubber. The friction characteristics of rubber are the basis for tire rolling. The friction between rubber and the ground provides the grip of the car, but it also brings rolling resistance. Obtaining the relationship between rubber friction and the aforementioned factors is of great significance for improving tire rolling characteristics, reducing rolling resistance, improving grip, and developing energy-saving and environmentally friendly tires. ...
