针对泵车产品设计成本高和开发周期长的问题,采用模块化建模方法建立了泵车模块化产品开发平台.以泵车销轴为例,通过模块几何形状和结构参数分析,建立了销轴模块的主模型、主文档,生成了不同的销轴工程图实例.对泵车一级模块和二级模块的模块接口进行了类别划分.根据产品数据管理系统（PDM）和产品主结构,构建了订单产品模块化设计需要的模块分类树,划分出了泵车的基本模块、必选模块和可选模块,在此基础上进行了产品结构参数系列化设计和产品结构模块系列化设计.泵车模块建模方法在企业的实践结果表明：该方法减少和优化了约30％的零部件品种规格,缩短了近50％的产品研发时间,在降低生产成本的同时还提升了泵车产品的研发质量和品牌竞争力.

英文摘要：

Aiming at high design cost and long development cycle of truck-mounted concrete pump, the modular product development platform of truck-mounted concrete pump was established by modular modeling method. The axis pin was taken for instance,the module master model, the master document and different engineering drawings of axis pin were created by means of module geometry and structural parameters analysis. The interfaces of level one and level two modules were divided by category. According to product data management system（PDM）and product master structure,the module classification tree of modular design of order product was constructed and the basic modules, required modules and optional modules were divided, on the basis of this, the parameters serialization design and module serialization design of product structure were studied. The results indicate that the method can reduce and optimize about 30% of the parts of different specifications, cut down product development time by 50%. The method not only can reduce the production costs, but also can improve the quality of truck-mounted concrete pump product, enhance the brand competitiveness.
