Research on frame performance bandwidth of a pickup truck driven by fully parametric model
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.
