。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to railroad vehicle tracks, and is particularly concerned with railroad vehicle tracks that are advantageous for tracks on which vehicles run at high speeds.

。Conventionally, among railway vehicle tracks, especially tracks with track slabs (so-called slab tracks), as shown in Figs. The structure was such that the thickness of the cement asphalt and track slab laid on top was constant. In this example, when a train ran on the tracks, when the stiffness of the train's bogie and the speed of the train were used as parameters, resonance occurred at a certain value, resulting in increased noise. Although it is possible to consider a method of increasing the damping effect, as long as the rail fastening devices are arranged at equal intervals and the thickness of the cement asphalt that acts as a spring is constant, it is possible to consider methods that increase the damping effect. This structure promotes resonance, and there are limits to the damping method.
ところで、従来の鉄道車両用軌道の例としては、例えば
、実公昭５１−２１４４５号公報等が挙げられる。By the way, as an example of a conventional railway vehicle track, for example, Japanese Utility Model Publication No. 51-21445 can be cited.

の折損が生じる恐れがあった。The above conventional technology (in this case, the rail fastening means are installed at equal intervals, the thickness of the cement asphalt or track slab, etc. is constant, and various conditions in the support system of the track rail for the traveling vehicle are equal) Therefore, the vibration generated in the running vehicle resonates with the above-mentioned track conditions, and a phenomenon occurs in which the above-mentioned vibration is increased.This vibration increase 6. Therefore, the vibration of the threaded member in the car body or bogie is increased. There was a risk of loosening or breakage of the strength member.

生する振動を共振によって増大させることのない鉄道車
両用軌道を提供することにある。An object of the present invention is to provide a railroad vehicle track that does not increase vibrations generated in a running vehicle due to resonance.
上記目的は、レール締結装置の配置間隔を一定にしない
こと、また，Ｍ道スラブを載せるセメントアスファルト

とにより、達或される。The above object is achieved by not making the spacing of the rail fastening devices constant and by varying the thickness of the cement asphalt or pad on which the M road slab is placed and the bounce constant.

らないようにする。The rails directly follow the movement of the train, but when the fastening devices fasten the rails at equal intervals, the vertical spring constants of the rails themselves, which are supported at both ends, are the same. Therefore, in order to prevent this situation from occurring, the rail fastening intervals are varied based on an arbitrary function or random number.Also, regarding the track slab including the rail fastening device installed on the subgrade concrete, both parties are contacted. By varying the thickness of the cement asphalt, the resonance point of the track slab at any given position is prevented from becoming constant.
パッドについてはレールの支持点そのもののばね定数を

ね定数を場所により変ｆヒさせることとする。Regarding the pad, in order to change the spring constant of the rail support point itself, the thickness of the pad and the spring constant of the pad itself will be varied depending on the location.
このように軌道におけるレール支持系の諸条件に変化を
与え、走行車両における振動の共振に伴う増大を防止し
、車両に起る不具合を防止する。In this way, the various conditions of the rail support system on the track are changed, and vibrations in the running vehicle are prevented from increasing due to resonance, thereby preventing problems occurring in the vehicle.
