摘要
随着高速机车运行速度的不断提高,机车在运行中承受的冲击和振动等载荷作用变得越来越复杂。牵引变流柜作为机车中极其重要的部分,这就对它的柜体性能提出了更高的要求。进而以某型机车变流柜柜体为研究对象,采用有限元前处理软件Hypermesh对其建立有限元模型;运用Goodman疲劳曲线对变流柜进行疲劳强度评估,依据标准BSEN12663-1-2010《铁道车辆车体结构要求》采用ANSYS软件对变流柜进行了静强度分析及模态分析。由计算结果可知,变流柜模态多集中在低频10~40Hz,符合所依据的标准。
With the continuous increase of the running speed of high-speed locomotives,loads such as shocks and vibrations during the operation of locomotives become more and more complicated. As the extremely important part of the locomotive,the traction converter cabinet puts forward higher requirements for its cabinet performance. Taking a certain type of locomotive converter cabinet as the research object,the finite element pre-processing software Hypermesh is used to establish a finite element model for it;The Goodman fatigue curve is used to evaluate the fatigue strength of the converter cabinet,and the static strength analysis and modal analysis of the converter cabinet are performed by using the ANSYS software in accordance with the standard BSEN12663-1-2010"Railway Vehicle Body Structure Requirements". It can be known from the calculation results that the mode of the converter cabinet is mostly concentrated in the low frequency of 10 to 40 Hz,which meets the standards on which it is based.
