摘要: 为了探究气密载荷对高铁司机室结构强度的影响,以某高铁产品为研究对象,利用Hypermesh软件建立司机室有限元模型,对其在气密载荷作用下的结构强度进行评估。根据强度评估结果,利用OptiStruct对侧墙复合材料铺层方案进行优化。研究结果表明:气密载荷作用会对司机室大开口附近的结构造成较大的位移;通过对复合材料铺层的优化,不仅可以改善结构位移,还能达到结构轻量化效果,优化后的结构位移减少了14.2%,质量下降了6.95%。

Abstract: In this paper, in order to investigate the effect of sealing load on the structural strength of high-speed railway cockpit,the cockpit of one high-speed train was taken as research target. First, Hypermesh was used to establish the finite element model of cockpit and the structural strength of cockpit under sealing load was evaluated. Then in response to the strength evaluation results, OptiStruct was used to optimize the layup of composite materials which were used in the side wall of cockpit. The research result shows that the effect of sealing load causes a large displacement close to the large opening structure. At the seam time, by optimizing the layup of composite materials, not only can the structural displacement be ameliorated, but the structural lightweight effect can also be achieved. The structural has a 14.2% reduction in displacement and a 6.95% reduction in weight compared to the original design.
