| 摘 要： | 运用热力学基础知识，建立了一种计算高速列车通过隧道时车内压力变化的热力学模型，它采用当量漏气面积表示车辆气密性，具有物理意义明确的特点。在相同的计算条件下，将其与现有能够计算车内压力的2种模型——经验模型和流动模型进行了车内压力计算的对比分析，结果表明热力学模型用于高速列车车内压力计算是可行的。

| Abstract: | The paper cpplies the basic knowledge of thermal dynamics and builds a thermal dynamics model to calculate the verying interior pressure of high-speed trains going through tunnels. The model uses the equivalent leakage area to indicate the sealing characters of trains. The equivalent leakage area has definite physical meaning. The model is compared with the existing experience model and flow model in calculating the interior pressure of trains under the same calculation conditions. The results indicate that the thermal dynamics model is feasible in calculating the interior pressure of high-speed trains. |
