摘　　要：通过对现场实测数据进行统计整理,对某型有轨电车的运行安全性和平稳性进行综合评估。试验车四节车厢转向架上均加装轮轨力检测设备,用以检测列车的安全性指标,车体上加装振动加速度传感器,检测列车运行平稳性。构架端部加装振动加速度传感器,用以检测列车运行稳定性。通过数据统计计算,发现在不同工况下以及处于不同位置的车体的运行稳定性指标略有差异,整体来说,动车的运行品质取决于拖车,中间车运行品质取决于两端的车。The comprehensive evaluation on the peration safety and stability of a certain type of tram is conducted through the statistical analysis of field measured data. Four car bogies of the test vehicle are equipped with wheel rail force detection equipment to detect the safety index of the train, and the vehicle body is installed with vibration acceleration sensor for detecting the running stability of the train. The vibration acceleration sensor is retrofitted at the end of the frame to check the stability of train operation. Through the calculation by statistical data, it is found that the operation stability indexes of the train body differentiate slightly under different working conditions and in different locations. As a whole, the operation quality of bullet train depends on trailler, while the operation quality of intermediate train lies on cars at both ends.
