CAD System Dedicated to the Design of Sport Bike Frame Structure

This article aims to discuss the design process of the CAD system dedicated for sport bike frame structure, introducing in detail its design concept and the scheme of implementation. Based on the different usages of sport bikes and the requirements on the system made out by Beijing Hanglun Sport Apparatus Company Limited. Structural analysis on two types of bikes frames is carried out. The system defines the basic design parameters and analyses the constraint conditions.Then calculating formulas with constraint conditions are derived. The system solves equations with Visual C++ program, realizes input of the original data and output of the results through interactive system. With AutoCAD14.0 as the platform, the system uses VC++ and ObjectARX to realize auto output of bike frame graphics. The system has been put into use. Practice has affirmed that the system抯 convenience, applicability and reliability all have reached the expected goal.

运动自行车车架结构的参数化设计

开发了运动自行车车架结构专用的ＣＡＤ设计系统，详细介绍了系统开发的各个环节中的设计构思及具体实施方案．基于运动自行车的不同用途以及企业对系统提出的要求，对两种类型自行车的车架进行了结构分析，确定基本设计参数，再进行约束条件分析，从而推导出计算公式和带约束条件的方程．利用ＶｉｓｕａｌＣ＋＋程序段实现计算和解方程，通过对话框实现ＣＡＤ系统的原始数据的输入和计算结果的输出．此设计系统从根本上解决了传统设计中存在的计算繁琐、设计复杂和周期长等问题。
