摘　　要：针对现有机械产品设计的个性化、系列化和效率不能满足客户需求的问题,对产品设计前期的建模思想和装配方法等方面进行了研究。建立起了一种在产品设计过程中,以"顶层基本骨架"(top basic skeleton,TBS)建模方法为设计思想,利用EDS参数化设计软件为工具,从客户需求开始,到整体装配模型,再到局部零部件的设计方法;通过对电梯轿厢的变结构体参数化设计试验,在建模参数和设计对象的尺寸参数控制方面实现了唯一、实时的对应关系。研究结果表明:基于TBS思想与参数化方法相结合,能够有效地提高机械产品设计效率,缩短设计周期,满足客户对个性化和可靠性的需求。Aiming at the problems of the mechanical product design such as individualization,serialization and efficiency that can＇t meet customer＇s needs,then the product design early modeling ideas and assembly methods and other aspects were studied. A new method of product design process beginning from the customer＇s needs,to the overall assembly model,then to the local components was established,which came from the modeling thought the top basic skeleton（ TBS） and the parametric design tool EDS. Through the parametric design of the variable structure of the elevator car,the only real-time correspondence between the modeling parameters and the size parameter control of the design object was achieved. The research results indicate that the combination of TBS and parameterization can improve the efficiency of mechanical product design,shorten the design cycle and meet the requirements of customers for personalization and reliability.
