摘　　要：依据欧盟标准BS-EN13749:2011和EN12663:2010,得到了国内某型低地板有轨电车车体静强度载荷工况,并计算了牵引座、减振器座等在超常工况和模拟运营工况下的载荷。采用Hyperworks软件分析了有轨电车的静强度以及牵引座等的疲劳强度,并利用Goodman疲劳极限图法对计算结果进行了分析评估,结果表明此低地板有轨电车满足相关标准和规范的结构强度要求,达到了验证其结构安全性的目的。Based on the standards of European Union BS-EN13749-2011 and EN12663-2010,it presents the static load condition of a low-floor tramcar body in China.It calculates the load of traction seat,shock absorber seat and so on under abnormal operating conditions and operating conditions,analyzes the static strength of the tram and the fatigue strength of the traction seat in Hyperworks software,and evaluates the calculation results with the Goodman fatigue limit map method.The results show that the low floor tram satisfies the structural strength requirements of the relevant standards and codes.And the calculation achieves the purpose of verifying its structural safety.
