Abstract

<P>PROBLEM TO BE SOLVED: To provide an air current separation restraining structure of a moving body capable of restraining separation of an air current from the forefront part of the moving body by a simple structure. <P>SOLUTION: A separation restraining part 6 restrains separation of an air current F from the forefront part of a vehicle 2 by introducing the air current F collided with a vehicle body end surface 3a of the vehicle 2 to vehicle body side surfaces 3b and 3c and a vehicle body upper surface 3d of this vehicle 2. When the vehicle 2 travels in the X axis direction, the air current F collided with the vehicle body end surface 3a of the vehicle 2 flows in from inflow ports 7a and 7d of ventilation parts 7A-7C, and flows out of outflow ports 7b and 7e by passing through pipes 7c and 7f. Thus, the air current F is introduced to the vehicle body side surfaces 3b and 3c and the vehicle body upper surface 3d from the ventilation parts 7A-7C, and the air current F flows along these surfaces. As a result of it, an increase in the apparent cross-sectional area of the forefront part of the vehicle 2 by separating the air current F collided with the vehicle body end surface 3a of the vehicle 2 is restrained, and a pressure variation generated when the vehicle 2 rushes into a fixed structure such as a tunnel is reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an air flow separation suppressing structure of a moving body that suppresses the separation of the air flow from the leading portion of the moving body when the moving body moves.

  Conventional railcars are provided with plate-like members that are curved toward the center of the vehicle body on both sides of the front face of the leading vehicle in order to suppress the occurrence of airflow on the side of the vehicle body when the vehicle is running (for example, Patent Document 1). In such a conventional railway vehicle, the airflow that collides with the front face of the leading vehicle is separated and guided to the upper and lower parts of the vehicle body by the plate-like member, thereby suppressing the airflow generated on the side of the vehicle body during vehicle travel, Train wind generated on the platform is reduced.

JP 2003-246265 A

  When a high-speed train enters the tunnel entrance side tunnel, a compression wave is generated in the tunnel. This compression wave propagates through the tunnel. Then, when the compression wave reaches the exit-side wellhead, tunnel micro-pressure, which is a pulsed pressure wave, is released to the outside. On the other hand, the compression wave is reflected at the tunnel entrance and the train end and reciprocates in the tunnel, causing pressure fluctuations on the train. The pressure fluctuation causes a so-called “ear-dropping” phenomenon in the vehicle. It is considered that these phenomena are mainly related to the magnitude of the pressure of the compression wave formed when the train enters and the pressure gradient (pressure change time).

  In recent years, the speed of conventional lines has increased due to improvements in vehicle performance and linear improvements, especially for the compression waves formed when entering a tunnel of a gable train with almost no roundness at the end of the head. The gradient tends to increase. The main cause of these increases is thought to be an increase in the apparent vehicle cross-sectional area due to the separation of the flow from the gable head of the train. As the magnitude of the pressure of the compression wave and the pressure gradient increase, there is a tendency for the earloin, tunnel micro-pressure wave, etc. to increase. On the other hand, it has been found that there is a problem that the air resistance of the train increases as the flow separation from the head increases.

  However, in the conventional railway vehicle, the purpose is to reduce the train wind generated on the platform. When the airflow colliding with the front face of the leading vehicle is guided upward and downward by the plate member, the upper and lower surfaces of the vehicle body There is a risk that the air current will peel off. As a result, the conventional railway vehicle has a problem that a tunnel micro-pressure wave is generated even though the train wind can be reduced.

For this reason, the apparent cross-sectional area of the leading portion of the vehicle 2 increases due to the separation of the air flow F from the vehicle body end surface 3a, and the pressure fluctuation generated when the vehicle 2 enters the fixed structure such as a tunnel increases.

  On the other hand, when the vehicle 2 travels in the X-axis direction in the state where the separation suppressing unit 6 shown in FIGS. 1 to 7 is present, the airflow F that collides with the vehicle body end surface 3a of the vehicle 2 becomes the inlets 7a, 7a, 7C of the ventilation units 7A-7C. It flows in from 7d, passes through pipes 7c and 7f, and flows out from outlets 7b and 7e. For this reason, the airflow F is guided from the ventilation portions 7A to 7C to the vehicle body side surfaces 3b and 3c and the vehicle body upper surface 3d, and the airflow F flows along these surfaces. At this time, the guiding portion 8 guides the airflow F colliding with the vehicle body end surface 3a of the vehicle 2 to the inflow ports 7a and 7d. When the airflow F collides with the leading end of the guide portion 8, the collided airflow F is separated at the leading end, but the separated airflow F is guided to the front end portions of the vehicle body side surfaces 3b and 3c and the front end portion of the vehicle body upper surface 3d. Reattach to these front ends. For this reason, the airflow F is guided from the front end portion of the guide portion 8 to the vehicle body side surfaces 3b and 3c and the vehicle body upper surface 3d, and the airflow F flows along these surfaces. Further, the airflow F colliding with the vehicle body end surface 3a is stopped by the inner side surface of the guide portion 8, and the airflow F is prevented from being separated from the vehicle body end surface 3a. As a result, when the air current F colliding with the vehicle body end surface 3a of the vehicle 2 is separated and the apparent cross-sectional area of the leading portion of the vehicle 2 is prevented from increasing, the vehicle 2 enters the fixed structure such as a tunnel. The pressure fluctuation generated in the is reduced.
