扩展厢式展览车扩展壁板的设计

摘要

采用Shell 91和Shell 99 2种单元混合离散方法,对扩展厢式展览车的可扩展壁板进行了有限元计算分析,确定了满足展览车使用要求的壁板结构,对采用混合离散方法分析复合夹芯板承载特性的新方法进行探索,为类似结构的设计分析提供了有益参考.%This paper analyzes the finite element calculation for extendable panels of extendable exhibition van with two element hybrid discrete methods which are Shell 91 and Shell 99, determines the panel structures meeting the requirements , and studies the new method of analyzing load-bearing characteristics for composite sandwich panel applying hybrid discrete method. It provides beneficial reference for design analysis of similar structures.
