基于频响分析的某车型复合材料后车门的模态参数识别分析

Modal Parameter Identification Analysis of Composite Rear Door of a Certain Model Based on Frequency Response Analysis

以某车型的复合材料后车门为研究对象,基于有限元分析方法,通过对复合材料车门在自由模态下的频响分析,识别出车门在一阶模态下的弯曲和扭转特性,为复合材料车门结构设计提供指导。

Taking the composite rear door of a certain model as the research object, based on the finite element analysis method, the bending and torsion characteristics of the composite door in the first-order mode are identified through the frequency response analysis of the composite door in the free mode, which provides guidance for the structural design of the composite door.
