In order to improve the safety of the braking process of high-speed train. the brake disc heat dissipation structure needs to be optimized. The ANSYS-workbench software was used to establish a three-dimensional transient model. The temperature field simulation was performed on the brake discs with 8 different structural parameters based on the energy folding algorithm. https://www.chiggate.com/turbo-air-m3f72-3-n-78-wide-m3-series-reach-in-freezer-featuring-three-solid-doors-energy-star-online-now/
