摘要
根据一维可压缩非定常不等熵流动模型和广义黎曼变量特征线法,建立了高速列车通过隧道间隔距离小于列车长度的隧道群过程中引起压力波动的计算方法和计算程序,并初步进行了参数研究,为今后对该类问题的研究提供了参考依据.
Based on one-dimensional unsteady compressible non-isentropic flow prediction and the method of characteristics expressed in generalized Riemann Variables, the paper established numerical method and procedures of pressure wave when the high-speed train passed tunnel group between which the space is less than the length of train, and studied the parameter. The presented result provides consultation for later study of this kind of problem.
