| 摘 要： | 根据CW-200K转向架构架的结构和承载特点,运用Solidworks建立构架的实体模型,并将模型导入AN-SYS中进行有限元分析,依据分析结果并参照标准JIS E4207—2004和焊接材料的Goodman疲劳极限图对构架进行疲劳强度评估.此外,还对构架进行模态分析,分析构架在某一频域内的振动模态,从而评价构架的动态性能是否满足设计要求.分析结果表明:各关键点的等效应力均小于许用值,构架满足疲劳强度的要求;构架的最低自振频率为33.944 Hz,能够有效地避开激振频率.这为优化构架结构提供相关的参数依据.

| Abstract: | Based on the structure and load characteristics of CW-200K bogie frame,the solid model is built by using Solidworks according to the structural parameters of CW-200K bogie frame.According to the analytical results,the fatigue strength of the frame is checked referring to JIS E 4207 and Goodman sketch for welding materials.In addition,the modal analysis of the frame is made and the vibrational modal of frame in given frequency-domain is predetermined to evaluate the dynamical behavior of the frame in order t... |
