摘要: 为实现概念设计阶段在汽车模块化平台下对汽车白车身结构进行的模块化设计,提出一套划分模块并从中筛选出共享模块和非共享模块的方法。首先,在保证车身性能的同时考虑车身制造成本和装配成本,提出一种改进的图分解算法,进而能够定义出车身装配结构的最佳划分方式,并依此进行车身结构模块的划分;以该划分方式为基础,根据结构发生改动时所涉及到模具的成本和制造的复杂程度进行优先级排序,定义并筛选出其中的核心共享模块、参数化设计模块和柔性调整模块;在施加平台级约束后,平台下某车型的性能和单独优化该车性能的差值应控制在一定范围内,可根据该差值是否满足要求动态调整三种模块的筛选结果。算例以某三款车型的白车身底板为对象进行了划分和筛选,结果证明了该方法的有效性。

Abstract: In order to realize the modularity design of the body-in-white (BIW) at the concept stage, a method for module identification and selection is proposed. Based on considering manufacturing costs and assembly costs, a modified graph-partitioning algorithm is used to optimally divide the vehicle body assembly structure into a set of components, which also means, modules. In the next moment, sort the order of the molds by differing cost values, then define and divide three different kinds of modular from the BIW structure:Kernel module, parameterized module and flexible module. After applying the platform constraints, the performance differences of a car build on a platform or not should not be evident, otherwise, a dynamic regulation should be adjusted in accordance with the difference. In the example, the result of the module identification and selection proves the effectiveness of this method.

Key words: BIW, conceptual design, modular platform, module identification, module selection
