Based on the object-oriented technology, a visible interactive platform for braking system is developed by making use of Visual C++ 6.0 development tool. By using the VC++ and doing secondary development on other softwares, the software possesses powerful features, such as brake plan selection, performance calculation, parametric modeling, kinematics simulation, etc. With the help of visualization, the software can help the users take part in the design process and improve the design efficiency.
