Structural and parametric synthesis of disc and brake
In the process of structural-parametric synthesis of a disc-shoe brake, a structural diagram of the brake mechanism was built. Input and output parameters were determined for each element of the disc-shoe brake structure in the process of parametric analysis. According to the structure of the brake disc-shoe type for one element, the input parameters were the output parameters of the previous element, according to the principle of the hierarchy of the developed structure. The difference between structural-parametric synthesis and structured and parametric synthesis is that when the parameters of the constituent elements change, the structure can change during the design. To develop a design methodology based on structural-parametric synthesis, it is necessary to determine the resulting parameters of each element of the structure of the brake mechanism. Based on the resulting parameters, a block diagram with a multivariate cooling system was developed. Depending on the resulting parameters (the input parameter is the temperature on the working and non-working surfaces; the output is the temperature head), it is possible to change the cooling system of the disc-block type brake mechanism. Options include forced and combined cooling systems. The forced cooling system is characterized by the presence of a brake disc ventilation device, the cooling process is realized without additional turbulators and means for injecting an air flow. A forced cooling system is a developed design for injecting air masses to increase the rate of heat transfer from heated friction pairs. Combined cooling includes both the presence of a ventilator and special cooling systems. On the basis of structural-parametric synthesis, it is possible to develop a methodology for designing brake mechanisms of a disk-shoe type for various branches of mechanical engineering.
