高速铁路接触网在线防冰过程横向温度场研究
|
摘要
基于热平衡方程推导出接触网在线防冰过程的临界防冰电流。借用ANSYS有限元仿真软件,建立接触网整体吊弦模型,对接触网系统在线防冰过程的横向温度场进行仿真分析。利用流体分析模块,对接触线和承力索温度场进行流-固耦合分析。研究结果表明,基于整体吊弦模型的接触网的温度场分布与通过流-固耦合模型仿真所得结果基本吻合,且与预期目标温度接近,验证了仿真模型及分析方法的正确性。
The critical anti-icing current of catenary during online anti-icing was deduced based on the heat balance equation for catenary. Then a whole dropper model was built by utilizing the finite element simulation software ANSYS, which was used to study horizontal temperature field of catenary system during online anti-icing in high-speed railway. Fluid-solid coupling simulation analysis for message wire, contact wire and electric connecting clamp were performed by the fluid analysis module. The simulation results reveal that the temperature field distribution of catenary acquired from whole dropper model analysis is in good agreement with those from fluid-solid coupling simulation analysis, and they are close to the expected target temperature, which verifies the correctness of the model and methods.
