摘要
为对浮置板轨道结构参数进行动态优化设计,采用ANSYS软件中的缩减法对结构进行模态分析,研究结构的振动特性。在此基础上,详细分析浮置板长度、密度和钢弹簧支承间距、刚度4个结构参数变化对固有频率的影响。由分析结果可知,在满足结构相应要求的前提下,可以适当增加浮置板的长度、密度和钢弹簧支承间距,或者适当降低钢弹簧的刚度。
In order to optimize the floating slab track dynamic structure, the structure modal was analyzed with the help of the software of ANSYS and the reduction method and the vibration characteristic of the structure was studied. On the basis of this, the effects of the length and density of the floating slab and the spacing and stiffness of the steel spring on the natural frequency were analyzed. The results show that the length, density of the floating slab and steel spring bearing spacing should be appropriately increased or the stiffness of steel springs should be appropriately reduced with the demand of the floating slab track structure.
