Abstract

Abstract:

A MDO model of TWC was firstly established by using TWC conversion efficiency, pressure loss, miss and thermal shock resistance as the objective function and the MDO model was solved on the basis of taking full account of the coupling effects among various disciplines by using self-adaptive chaos algorithm and VB(visual basic) programming. The optimization results show that pressure loss reduces 699%, mass reduces 1168%, displacement deformation reduces 2091% and the conversion efficiency improves 542%. The tests prove that MDO in TWC is effective.

Key words: three-way catalytic converter(TWC), multidisciplinary design optimization(MDO), chaos algorithm, emission control, engine

摘要：

以车用三效催化转化器（TWC）的转化效率、压力损失、质量以及抗热冲击性能为目标函数,建立了TWC多学科设计优化（MDO）模型。在充分考虑各学科之间的耦合效应基础上,通过采用自适应混沌优化算法与VB编程对MDO模型进行求解。优化结果表明,压力损失减少699%,质量减少1168%,位移变形减少2091%,TWC转化效率提高542%。试验证明该方法用于TWC是有效的。
