Problems solved by technology

The disadvantages of this method are: firstly, it is not conducive to economic development, and the railway system may be paralyzed at any time due to weather; secondly, because the crosswind is changing rapidly, the method of speed reduction cannot reliably ensure the safe operation of the train
This method has long engineering time, slow effect and high cost

Abstract

The invention discloses a crosswind hazard inhibition method of a train and a device thereof. The method comprises the following steps of: A. establishing a crosswind security database; B. measuring the running speed of a train by a speed monitoring device arranged on the train, and measuring the current wind speed and wind direction by a wind measurement device arranged on a railway line or an on-board wind measurement device; C. installing wing plates with regulable angles of attack at both sides of the top of the body of the train, wherein the actuators of the wing plates are connected with an on-board control computer; and D. the on-board control computer calls the crosswind security database to calculate and judge according to the measured running speed of the train and the measured wind speed and wind direction and outputs a corresponding command to control the actuators to actuate to regulate the angles of attack of the wing plates so as to inhibit the influence of the crosswind on the train. The method can change the balance characteristic of the train in the running process under the crosswind action, thereby ensuring the safety, the stability and the high-speed running of the train, and the cost is low.

Description

technical field [0001] The invention relates to a method and a device for suppressing train crosswind hazards. Background technique [0002] The train relies on the unique wheel-rail constraint relationship to run near the ground, and its length is longer than other means of transportation. This causes the train to be sensitive to side winds. The crosswind not only affects the stability of the train, but also threatens the safety of the train when the crosswind is strong. In the mountains, coasts, etc., the surface contours are changeable, and the atmospheric ground boundary layer forms a strong natural wind here. When the train runs in these places, due to the influence of the strong wind, the aerodynamic performance of the train deteriorates, the restraint relationship between the wheel and the rail is destroyed, and the lateral stability of the train deteriorates. Cause train derailment, overturning and casualty accidents. [0003] my country has a vast territory and ...
