Finite Element Analysis of Hoop-load Windshield with Random Gaps
摘要
Abstract
Hoop-load windshield is a structure that can transmit the fuselage load,the randomness of the assembly boundary gaps,however,directly affects the internal loads of the windshield during hoop loading.Based on the finite element simulation method,the relationship between the assembly gaps and the flexibility of the fastener was studied with the help of a single-fastener finite element model.The mechanical model between the assembly gaps and the flexibility of the fastener was established.By introducing random gaps flexible parameters for each fastener of the wingshield fine finite element model,the FEA simulation of the hoop-load windshield with random assembly gaps was realized,and the influences of the dispersion of the windshield gaps on the hoop-load windshield was analyzed.关键词
