摘要
采用SFE-CONCEPT建立隐式参数化模型,针对目前依靠经验法对模型修正效率低的问题,以驾驶室白车身的部分地板参数作为变量,以各目标仿真值与实测值之间的误差为目标,采用响应面近似模型与NSGA-Ⅱ优化算法,建立白车身模型修正的流程,为后续的优化分析做好准备工作。
Sfe-concept is used to establish implicit parametric model. Aiming at the problem of low efficiency of model correction based on empirical method,taking some floor parameters of cab BIW as variables,taking the error between simulation value and measured value as target,response surface approximation model and NSGA-Ⅱ optimization algorithm are used to establish the process of BIW model modification, which is good for subsequent optimization analysis preparation.
