| 摘 要： | 建立了跨坐式单轨车辆头车车体的三维几何模型和有限元模型,并对其进行模态分析,得到了该车体的固有频率和相应的振型.通过对计算结果的分析,指出了设计中可能存在的问题,提出了改进的建议.在低频段的外界激励下,车体的整体振动并不强烈,主要是裙板部分产生较大的振动;为抑制其振动,可采用前、中、后裙板之间进行连接并在后裙板与铝地板...

| Abstract: | A 3D geometry model and an FEA model of the straddled-type monorail vehicles' head-car body are established, the natural frequency and relevant vibration mode of the car body are obtained through the modal analysis.Some possible problems in the design are pointed out,and advices are also given to improve the design.This research can provide some reference for the structural optimization and fatigue analysis of the car body. |
