Each component of a power driving device is respectively arranged on the first support, the second support, the third support, the fourth support and the fifth support, a brake of a braking device is arranged on the brake caliper assembly installing support, the output end of the power driving device is connected with the input end of the braking device, sensor parts of a collecting measuring device are respectively arranged on the power driving device and the brake of the braking device, and the collecting measuring device is connected with a controller. A test table is compact in layout and easy to measure and control, an advanced testing technology and a control method can be fully utilized, test working conditions are convenient and accurate, and measurement of a brake friction, heating and vibration physical field is targeted.

Description

technical field [0001] The invention relates to the experimental field of brake characteristic research, in particular to a brake friction, heat generation and vibration coupling test bench. Background technique [0002] During the braking process of the brake, the braking torque fluctuation will be affected by the friction characteristics of the friction pair, the effective radius and the normal force. Among them, the friction characteristics of the friction pair are not only related to the relative sliding speed, but also closely related to the normal force of the friction pair and its fluctuation, and the temperature of the friction pair. At the same time, the DTV (brake disc thickness difference) and SRO (brake disc end surface runout) of the non-uniform brake disc will cause the change of the normal contact force of the friction pair, the pressure fluctuation, the overall vibration response of the brake structure and the dynamic movement of the piston, Will further aff...
