复合材料波纹梁的抗撞可靠性分析
Analysis of Crashworthiness Reliability for Composite Corrugated Beam
摘要
Abstract
Composite corrugated beam is widely used for excellent specific energy absorption characteristics.However the structure parameters and material properties of the composite material have large dispersion,some of them impact on the crashworthiness of composite corrugated beam.Therefore,analysis of crashworthiness reliability by considering the uncertainty parameters which has greater impact on crashworthiness has important engineering significance.In this paper,for these non-probability uncertainty problem of elastic constants of composite material,introducing the technology of multi-dimensional ellipsoidal convex model,by combined with explicit finite element technology and response surface modelling technology,uncertainty propagation analysis is conducted,so as to find out the uncertainty parameters which have a great influence on the crashworthiness of corrugated beam,and then to analyze the crashworthiness reliability of corrugated beam.The results show that the crashworthiness reliability analysis method of composite material based on the multi-dimensional ellipsoidal convex model has high precision and strong practicability.关键词
