Shanxi, Xinjiang Xianghe Machinery Co. Share: Introduction to thermal analysis in the study of the brake disc braking system, the thermal analysis is still in a primitive stage. In the braking phase, high temperatures and thermal gradients, which creates pressure and deformation, this effect will be displayed on the appearance and increase the cracks. Then it is important to accurately determine the temperature field in the disc brake. When the parking brake, the temperature is not the time to be stabilized at the brake disc. A transient analysis is necessary. It is essential to identify the thermal gradient, which is three-dimensional modeling of the problem requires. Heat load performance in heat flux into the brake disc by the brake pads. A lot of heat in the brake disc and pad contact surface produced no doubt caused a rotor in the region of non-uniform temperature distribution, but in mutual sliding in a heated environment is constantly liner. This the contact surface of the disc brake to determine the temperature distribution in the transient thermal analysis was carried out. The problem with this disc and fixed-bearing mutual sliding frictional heat generated by the effect of the uneven distribution of finite element model tests There are several possible applications in the automotive heat transfer coefficient. Temperature cycle brake disc brake distribution can have a comparison, during braking analyze each case under the energy conversion in the final release of the cycle are equal. Change procedure is used to develop a mobile heat source, like heat convection cooling line. Difficulty in accurately simulate the rotation of the rotor by heating it using the code is ignored hand brake disc, which is responsible for ensuring that the curve formed so that the heat flux at a later time to enter the brake disc. In this study, we will be in a three-dimensional numerical simulation of the whole exhibit to analyze the thermal behavior and ventilated disc brakes. Calculate calories based on finite element method will use software ANSYS 11. Shanxi, Xinjiang Xianghe Machinery Co. share: Economic Analysis of brake discs generally consists of pearlite gray cast iron. The structure has a flat shape and hat switch two latter part of the length of the cylinder layout size, plate-shaped brake disc machining sequence simple, so the costs are greatly reduced. To improve cooling, some pliers disc brake disc cast middle layer disc radial ventilation bad, can greatly increase the cooling area, but the larger overall thickness of the disk. Manufactured by caliper QT400-18 KTH370-12 malleable iron or ductile iron, also made with light alloy brake disk can be made whole, but also do half by bolting. Taking into account the cost of the economy, it is necessary to have both consider the overall performance of the brake, the choice of hat-shaped structure, using no intermediate ventilated brake disc; caliper selection of ductile iron, and made the whole work; the hub of manufacturing material selection gray cast iron. Relative to evaluate the cost of this form of brakes in the middle and upper levels, but also have to consider cost efficiency on the factory processing.
