摘要
应用有限元软件ANSYS建立包括焊缝、螺栓和铆钉连接的某地铁铝合金头车车体结构的有限元模型。按照EN12663-1:2010和EN 1999-1-3:2007标准确定车体的15个载荷工况,计算车体在AW2工况下的疲劳强度。研究结果表明,在所有疲劳工况下,头车车体的焊缝、螺栓和铆钉等的疲劳寿命均满足30年最小使用寿命的要求。
Finite element model for the car body structure of aluminum alloy metro vehicle including weld,establishes the bolt and rivet by using the finite element software ANSYS.The 15 load cases are determined according to EN12663-1:2010 and EN 1999-1-3:2007 standard,the fa?tigue strength of the head car body in AW2 condition are calculated.The results show that the fatigue life of the weld,bolt and rivet of head car body meets the minimum service life of 30 years in all fatigue cases.
