“阿里安”运载火箭的箭体和/或有效载荷及被抛投的半整流罩之间必须避免发生任何碰撞.必须通过分析和试验来确定相应的最小间隙.在简单地介绍整流罩结构和有限元模型后,作了分离分析研究.研究重点放在几何非线性效应上.将现有研究试验数据与相应的分析推算进行了比较,从而可以对整流罩的有限元模型进行改进,以供未来研究之用. Any collision between the “Arion” rocket launcher’s rocket body and / or payload and the thrown semi-cowl must be avoided. The corresponding minimum clearance must be determined by analysis and testing. After a brief description of the fairing structure and Finite element model, made a separation analysis of the research focus on the geometric nonlinear effects.Experimental data of the existing research and the corresponding analysis and calculation are compared, so that the finite element model of the fairing can be improved for Future research purposes.
