Simulation Study on the Design of Air Brake Valve for Automobile Applications

Air brake valves are widely used in automotive braking systems and the Korean automobile industry depends on importing them. Therefore, we should develop the technical expertise for their domestic production. In this study, air brake valves were analyzed that can be used in a variety of automobiles. Computational fluid dynamics analysis, static structural analysis, and hyper-elastic analysis were carried out. Before production of an air brake valve system, the performance of different parts has to be evaluated, for instance by using finite element analysis. The structural stability of the product can be determined using static dynamics. The compression behavior of the O-ring is predictable by nonlinear hyper elastic analysis, although errors are possible due to one-way loading. This simulation study can both save time and reduce costs compared to the development of experimental prototypes.

In this study, we evaluated using the finite element analysis of the structural safety of the bolt portion and simultaneous calibration Collet Tool structure of Pipe Fittings tool. Collet Tool was subjected to structural analysis can be applied to the piston action portions of the inner and outer piston maximum acting force (187.5Ton). Collet Tool bolt portion was subjected to structural analysis by applying a force(750Ton). Result of structural analysis, it will be considered to be structurally safe.
