摘 要: 车身零部件的设计是一个多因素制约与多评价标准的复杂过程,既与关联附件产生复杂约束关系,形成复杂的几何形态,同时也受到自身结构复杂的工程规则、工程约束、设计意图综合影响。本文基于工程多约束问题的车身零部件设计方法,以一个全局角度考虑实际设计过程中的多种复杂约束和设计变量,以多阶段灵敏度分析的优化机制进行高效设计,不仅“加速”解决问题的效率,并且“拓展”解决问题的维度。本文以复杂的车门分缝线设计作为典型案例进行说明,获得了合理有效的车门分缝线,相比于传统方法本文方法更具设计柔性、可靠性、合理性。 |

Abstract:The design of body parts is a complex process with multi-factors and multi-evaluation standards. It not only has complex constraint relationship with the associated accessories and forms complex geometry, but also by the comprehensive influence of complex engineering rules, engineering constraints and design intention. This paper considers multiple complex constrains and parameters in the actual design process from a global view, and uses the multi-stage sensitivity analysis optimization mechanism to perform efficient design. This paper is not only “accelerate” the efficiency of problem solving but also “extend” the dimension of problem solving. This paper takes the parting line design tool for vehicle door as an example and obtains a reasonable and effective result. Compared with the traditional method, this method is more flexible, reliable and reasonable. |
