摘要
利用I-DEAS软件对客车车体承载结构的两种形式—封闭环和非封闭环结构进行了对比分析,分析结果表明:封闭环结构在强度、刚度以及舒适性方面均优于非封闭环结构.在客车车体承载结构设计时,在横向应尽可能形成封闭环结构.
Two kinds of load bearing structure of passenger car body.endosed and open ring structures are analyzed and compared. The results show that the intensity, stiffness and comfort of the enclosed ring structure are better than those of the open one. Therefore, enclosed ring structure should be applied transveisally when possible.
