Bicycle Parameterized Design System Based On Pro/Engineer

Now the further development upon the bicycle CAD system lags behind the increasing popularity of the application of the CAD system in our country. A fast bicycle design system is set up by the further development upon Pro/Engineer using VC++ 6.0 and Pro/Toolkit, which are the further development tools of Pro/Engineer. A method of combining three-dimension modeling technique with parameterized design is used in this system. Fast design of bicycle can be realized by transferring parts model, modifying model parameter and regenerating parts model in part library through Pro/Toolkit procedure module.First of all, a bicycle is divided into several parts such as front fork, saddle, handlebar and so on through analyzing its configuration and assembling characteristics. Original model of bicycle part is designed to set up bicycle part library through analyzing the shape and function of each part, using the functions of three-dimensional modeling and parameterized design of Pro/Engineer.Secondly, configuration chart of bicycle parameterized design system, reasonable user interface and procedure module of part parameter are designed after researching the method and characteristics of parameterized design of Pro/Engineer. Bicycle design system is set up by realizing the seamless integration between each application procedure module and Pro/Engineer system through Pro/Toolkit interface program design.Part model of using bicycle design is set up through regenerating model in bicycle part library, which avoids repeating work of series model design, enhancing design efficiency greatly. The further development upon the software system will provide a new solution for the application of commercial CAD software to the field of machine design.
