基于MDO方法的车用三效催化转化器设计优化
Design Optimization of Vehicle Three-Way Catalytic Converter Based on MDO Method
摘要
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 6. 99% , mass reduces 11. 68% , displacement deformation reduces 20. 91% and the conversion efficiency improves 5. 42%. The tests prove that MDO in TWC is effective.关键词
