摘要
利用ANSYS有限元分析软件对钢铝复合式第三轨(不锈钢)/受电靴(铜)的耦合温度场进行模拟分析,研究了模型在不同的电流(150～600)A条件下的载流摩擦耦合最高温度变化。结果表明:当相对滑动速度为120km/h和法向压力为150N时,耦合最高温度随电流的增大基本保持不变;当相对滑动速度为120km/h和法向压力为120N时,耦合最高温度随电流的增大先保持不变后升高;其它情况下耦合最高温度随电流的增大而升高。
The coupling temperature field for aluminum-stainless steel composite conductor rail （stainless steel）/collector shoe （copper）was simulated by finite element software ANSYS, and the maximum coupled temperature changing under different electric current（ 150-600 A ）of the model was studied.The results show that, when the relative sliding velocity is 120km/h and normal force is 150N,the maximum coupled temperature almost keeps unchanging;while relative sliding velocity is 120km/h and normal force is 120N,the maximum coupled temperature keeps unc hanging at firstly and then rises electric current; Under the other conditions ,he maximum coupled temperature rises electric current. with the increasing of with the increasing of
