Temperature Field Analysis for Brake Pad in High-Speed Braking Program Holding the Rail

The temperature field of brake pads in the braking holding rail is a key factor for the high-speed heavy test vehicle safe operation. Based on a braking test holding rail of the high-speed heavy test vehicle,a heat conduction model of brake pad was established according to the heat transfer theory and using the finite element simulation technology. A 3D thermal simulation model for the braking of brake pad was built by software ANSYS. Then the dynamic temperature field in the braking of brake pad was obtained. The relationship between the number of brake pads and the maximum temperature was obtained which is valuable for setting the initial number of brake pads before the real test.
