高速列车复合材料司机室混杂结构有限元分析

FINITE ELEMENT ANALYSIS OF COMPOSITE CAB FOR HIGH SPEED TRAINS

本文以典型高速列车钢制司机室结构为设计原型,利用有限元分析软件-ANSYS对其刚度和强度进行分析。在满足司机室对刚度和强度要求的前提下,提出了一种新型列车司机室结构形式-钢骨架复合材料司机室混杂结构。对比分析该结构形式与钢制司机室作,结果表明,利用玻璃钢泡沫夹芯材料设计复合材料司机室混杂结构,一方面可以提高司机室整体承载能力,另一方面可以减轻司机室20%自重。

A new composite sandwich cab structure for high speed trains is proposed in this paper. The cab structure is composed of steel framwork and composite sandwich structures with foam cores. A finite element modelof the cab structure is built to investigate the deformation and distribution of stress on the cab structure under appliedloads. Compared with a full steel cab of the high speed train, the new cab structure is of higher stiffness and 20%decrease in weight is achieved.
