"高速铁路隧道气动载荷研究：压力波及设备损坏分析"

The document "云计算-高速铁路隧道馈线及夹具气动载荷数值计算与试验研究.pdf" discusses the calculation and experimental research of aerodynamic loads on high-speed railway tunnels and fixtures. It emphasizes the high proportion of tunnels in the overall railway line and the potential challenges they pose. The interaction between trains entering tunnels and the generation of compression waves and expansion waves results in constantly changing pressure and loads on auxiliary facilities, which can lead to equipment fatigue and brake failure. The document acknowledges the impact of aerodynamic forces on tunnels and presents a comprehensive analysis of their numerical calculation and experimental research. It discusses the importance of understanding and mitigating these forces for the safe and efficient operation of high-speed railway systems. Overall, the document provides valuable insights into the complexities of aerodynamic loads in high-speed railway tunnels and the significance of thorough research and calculation in addressing these challenges.
