Abstract

Abstract:

In order to optimize the beam cross-sections of car body quickly and effectively in the conceptual design phase, a fast optimization method was proposed based on P1N1 plant growth algorithm. This method combined a database of the automobile body key section, taking into account the body styling, the internal space, the basic performance and other aspects of the manufacturing process constraints. By extracting the node coordinates and the performance parameters of the cross-sections, the node coordinates of beam cross-sections were imported into P1N1 plant growth algorithm as design variables to optimize, thereby controlling the beam cross-sectional shape. Based on P1N1 plant growth algorithm, a mathematical model and corresponding program were established. An application has proved this method can realize rapid optimization of beam cross-
sections of the automobile body efficiently.

Key words: automotive body; , beam cross-section; , database; , P1N1 plant growth algorithm, rapid optimization of cross-section

摘要：

为了在概念设计阶段快速有效地实现车身梁截面的优化设计，提出一种基于P1N1植物生长算法的截面快速优化方法。该方法结合汽车车身关键截面数据库，同时考虑了车身造型、内部空间、基本性能、制造工艺等方面约束条件。通过提取出截面数据库中的截面节点坐标以及截面性能参数，将数据库中梁截面的节点坐标作为设计变量，导入到P1N1植物生长优化算法中进行优化，从而控制梁截面的形状。建立基于P1N1植物生长算法的相关数学模型，并编制了相应的程序，通过算例验证了该方法能够高效实现车身梁截面的快速优化。
