基于超单元法的轿车白车身动态分析和优化
Dynamic analysis and optimization of car's body-in-white based on superelement approach
摘要
Abstract
An approach based on the superelement theory is proposed, and it is applied to model the cars body-in-white as well as to dynamic simulation and optimization. This approach can improve the calculation speed and do the dynamic optimization among substructures respectively in the cars body design. To meet the cars design of harshness, a dynamic optimal design model, based on the mean square of vertical displacement response at two points of the car floor, is also proposed. Satisfactory results are achieved in this paper.关键词
