Parametric Design For The Piston In The Front Whell Working Brake For Mineing Rubber-Tired Vehicle

The key to design the front whell working brake for mineing rubber-tired vehicle is to determination of piston structure size. The piston structure shape Will directly affect the brake friction lining pressure distribution between the friction pair of change trend, It determines the braking performance, it’s also the important factors to avoid partial loss brake, dual steel plate warping and Cracking failure phenomenon. Therefore, how to properly design wet multi-disc brake piston structure become the key problems in design.In this paper, the parametric design technology Introduce to mining rubber-tired work the front wheel brake piston (hereinafter referred to as the piston) design field, Piston parametric design is the key to its mathematical model is established. This article first analyzes discretization on the brake, Based on the principle of center of pressure distribution and temperature distribution principle, Through theoretical analysis On friction and contact with the lining of the piston end surface. And then, Mathematical model is established on Considering the thermal stability and grooved sealing performance of piston structure as a whole. Through a graphical topological relationship and geometric constraints between the mathematical model is set up, then determining the main parameters of piston parametric needed and time parameters. After drawing software secondary development function in comprehensive contrast and analyze the programming language. Based on Visual c++6.0as development environment, using CAXA2007EBADS secondary development platform of electronic board, establish application development guide engineering documents. According to establish parametric flow chart, first of all, use the resource editor and ClassWizard to add menu, dialog boxes, and other resources for visual editing, complete the user interface design. Then wrap used to connect to the database through ADO database access technology class. Finally the program design method based on physical characteristics, to parametric design of the piston, and list the key code. Eventually the design software is integrated with CAXA2007. This software friendly interface, reliable operation,which Verified by examples and Can quickly complete the piston drawings of the draw. And making preliminary static and modal analysis of structure on the piston three-dimensional entity model.
