Study on horizontal temperature field of high-speed railway catenary during online anti-icing
摘要
Abstract
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.关键词
