摘　　要：为提高设计质量和效率,并满足快速变型设计需求,在Creo软件平台支持下,采用自顶向下设计模式,通过骨架模型、关系式、尺寸约束、特征参照等参数化设计方法,实现设计信息从装配体向子装配体传递,再从子装配体向零件传递的过程。结果表明,该设计方法能有效降低设计出错率和工作重复率,尤其在进行系列化设计时,对关键参数信息调整后再进行模型再生,即可高效完成变型设计。In order to improve the design quality and efficiency and meet the requirements of rapid variant design,with the support of Creo software platform,the top-down design is adopted to realize the transfer of design information from assembly to sub assembly,and then from sub assembly to parts through parametric design methods such as skeleton,relations,dimensional constraints and feature reference.The results show that the design method can effectively reduce the design error rate and work repetition rate,especially in serial design,the variation design can be efficiently completed by model regeneration after adjusting the key parameter information.
