针对跨座式单轨交通系统的特点,提出一种大电流防融冰方案。基于焦耳热效应建立了单轨交通系统的T型专用导电轨的热平衡方程,计算其临界防冰电流,并分析温度、风速等环境因素对防冰电流的影响。为验证其可行性,在ANSYS中建立T型导电轨模型并对其进行热分析,结果显示计算得到的临界防冰电流满足实际所需。

英文摘要：

According to the characteristics of the urban monorail transit system,a melting ice plan of large current was proposed in this paper. Based on the joule heating effect,the heat balance equation of T-shaped special conductive rail in monorail transit system was established. Then the critical anti-icing current was calculated and the impact of environmental factors,such as temperature,wind speed,on the anti-icing current was investigated. In order to validate its feasibility,T-shaped conductor rail model was generated in ANSYS and the thermal analysis was carried out. The results show that the critical melting current obtained in this study can meet the practical needs.
