摘要
建立起波纹轨腰钢轨计算模型,运用有限元数值计算软件分别计算了平板、波纹两种轨腰在不同承载条件下的应力和位移,获得了大量的应力、位移计算数据,分析了两种轨腰结构的应力、位移分布规律和特点,为波纹轨腰钢轨的研究提供了数据支持。
A finite element model is founded, and large numbers of stress and displacement calculation data has been got by the finite element numerical calculation of flat waist rail and corrugated waist rail's stress and displacement under different load condition. After analysed the distribution and traits of two different waist rail construction's stress and displacement, this paper may provided data reference for the research of corrugated waist rail.
