Abstract: <P>PROBLEM TO BE SOLVED: To make impact sound by fine barometric wave lower than a conventional leading vehicle even in the case of a usual tunnel alone (in the case of no shock absorbing part) and even in the case of a tunnel provided with a shock absorbing part, in a high speed railway vehicle provided with a snow plough and a dividing/combining device.  <P>SOLUTION: When the vehicle runs into the tunnel with no shock absorbing part, a pressure gradient of a compression wave generated by the running takes the maximum value near a border of a lateral cross section area increase part Z11 at a front side and a lateral cross section area increase part Z12 at a rear side and becomes small toward a general part Z2. However, the lateral cross section area of a leading part Z1 is varied such that it again becomes large after it once becomes small at the lateral cross section area increase part Z12 at the rear side. The fact that the pressure gradient of the compression wave again becomes large after it once becomes small at the lateral cross section area increase part Z12 at the rear side is generated when the pressure gradient becomes a value near 80% of the maximum value after the pressure gradient becomes the maximum value.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
