| 摘 要： | 针对CRH2动车组动车转向架焊接构架,从模拟计算和线路实测两方面得到构架上关键部位的等效应力,并依据JIS E 4207规范进行了静强度和疲劳强度评估.两种分析结果的比较表明,各关键点的实测等效应力均小于计算值,这为正确使用规范以及制定符合我国线路条件的设计规范提供了依据.

| Abstract: | The equivalent stress at key positions of CRH2 motor bogie frame were obtained by using simulation analysis and online test.The evaluation of static and fatigue strength were carried out in terms of JIS E 4207 specification.Compared with the simulation results,the test stress values are lower.The comparison analysis provides foundation for establishing design specifications and test standards for trains used under Chinese line conditions. |
