摘要： 在基于仿真的汽车设计中，针对响应面模型普遍存在的精度不高的问题，研究了基于贝叶斯推断的模型外推预测方法，提出了模型不确定性下基于偏差修正的模型外推及可靠性设计优化方法，并通过一个汽车轻量化设计实例验证了所提方法的有效性。

Abstract: In simulation-based vehicle design, the Bayesian inference based model extrapolation method was further investigated,that was previously proposed by the authors, and a systematic bias corrected model extrapolation and RBDO under uncertainty was introduced. A real-world lightweight design problem of vehicle was employed to demonstrate the validity of the proposed method.

Key words: response surface；bias-correction, reliability-based design optimization(RBDO), model extrapolation
