汽车车身参数化设计技术研究

Study of Parametric Design Technique of Bus Body

通过对客车车身侧围的CAD建模 ,用参数化方法修改原有客车车身侧围的CAD模型参数 ,可以方便地建立新型客车车身侧围零部件的CAD模型 ,最后将其组装成整车车身模型。使用该方法可以大大缩短新车的开发时间 ,对提高汽车的市场竞争力具有重要意义。

On the basis of CAD model building of the bus body's side cover, dimensions of the model was modified with parametric method, and the CAD model of parts of new type bus body was built conveniently and then assembled to the whole bus body. This method can shorten time greatly for design of new bus model, and has important signification to improve competitive ability in automobile industry.
