摘　　要：为实现车型平台化性能开发设计,在概念设计阶段需开展细致的性能带宽研究。基于某皮卡平台车架架构尺寸平台化衍生策略,选定高关注的7项(前悬、轴距、后悬、车高、车宽、前开挡、后开挡)架构尺寸参数开展研究,利用MeshWorks工具建立了车架架构尺寸全参数化模型。通过参数驱动架构尺寸变形和DOE实验设计方法,在给定的设计领域内开展数值仿真寻优,探索了车架架构尺寸-性能-质量三者之间内在联系,建立了概念阶段开展线性工况下架构尺寸与性能规律探寻、性能-质量目标带宽精益化研究等工程技术方法,为项目概念及工程设计阶段开展多学科联合仿真优化的实现及基于有限元基型车模型快速衍生新的架构方案提供了方法。In order to achieve automotive platform performance development and design,performance bandwidth research is necessary to be conducted during the concept design stage.Based on the platform derived strategy of a given pickup truck platform frame architecture,seven architecture parameters(front suspension,wheelbase,rear suspension,vehicle height,vehicle width,front gear,and rear gear)were selected for studying.A fully parameterized model of frame architecture size was established using the Meshworks software.Through parameter driven architecture size deformation and DOE experimental design methods,numerical simulation optimization was carried out within a given design domain,exploring the internal relationship between frame architecture size performance weight,and establishing engineering and technical methods such as exploring the relationship between architecture size and performance law under linear load cases,and conducting lean research on performance weight target bandwidth in the concept stage.This provides a method for the engineering implementation of multidisciplinary joint simulation optimization in the conceptual and engineering design stages of the project,as well as the rapid derivation of new architectural solutions based on finite element vehicle models.
