[0040] It should be noted that unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the invention can be understood according to specific situations.

[0041] The following combines Figures 1 - 4 to describe the music track of the present invention and its design method.

[0042] Specifically, in combination with Figure 1 as shown, the music track described in this embodiment includes a roadbed 100, multiple sleepers 200 laid on the roadbed 100, a rail 300 laid on the sleepers 200, and a fastener 400. The fastener 400 connects the rail 300 and the sleeper 200.

[0043] Specifically, in the music track described in this embodiment, multiple sleepers 200 are arranged at intervals along the traveling direction of the rail vehicle on the roadbed 100, and the sleepers 200 are perpendicular to the traveling direction of the rail vehicle.

[0044] The steel rail 300 extends along the traveling direction of the rail vehicle and is perpendicular to the sleeper 200. Specifically, there are two steel rails 300, and the two steel rails 300 are arranged in parallel.

[0045] The fastener 400 is used to connect the sleeper 200 and the rail 300. Specifically, the fastener 400 includes a spiral spike, an elastic fastener, a gauge baffle and a baffle seat. The baffle seat is located in the slot of the sleeper 200, one side of the gauge baffle abuts against the baffle seat, and the other side of the gauge baffle abuts against the bottom groove side plate of the rail 300. The bolt spike passes through the elastic fastener and the gauge baffle from top to bottom in sequence, and is finally screwed into the bolt hole of the sleeper 200, and the rail 300 and the sleeper 200 are fixedly connected by the bolt spike. The elastic fastener plays a buffering role in the connection between the sleeper 200 and the rail 300.

[0046] Specifically, the track extends along the travel direction of the rail vehicle, which may be as short as a few kilometers or as long as thousands of kilometers. The section corresponding to the track is set as the music area 110. For example, in combination with Figure 1 As shown, the leftmost ballast unit 140 is a non-music area, and the two right ballast units 140 are music areas 110. When a rail vehicle travels in the music area 110, the vibration noise caused by the rail vehicle travel will be converted into different sound levels and become music. Specifically, the length of the music area 110 is set according to the duration of the music and the travel speed of the rail vehicle.

[0047] Specifically, a tuning assembly is provided in the music area 110 of the present embodiment, and the tuning assembly includes a first damping member 210 provided at the bottom of the sleeper 200. Figure 1 The bottom of the sleepers 200 in the middle music area 110 are all provided with the first damping member 210, and the connection relationship among the sleepers 200, the first damping member 210, the rails 300 and the fasteners 400 is only exemplarily described. In actual products, the sleepers 200 play a supporting role at the bottom of the rails 300, so a certain number of sleepers 200 with a certain spacing need to be kept at the bottom of the rails 300 to prevent the rails 300 from deforming. Since the speed of rail vehicles is relatively fast, the interval time between rail vehicles passing two adjacent sleepers 200 is relatively short, so the first damping member 210 is provided at the bottom of the corresponding sleepers 200 after spacing multiple sleepers 200, and it is not necessary to provide the first damping member 210 at each sleeper 200.

[0048] Further, for the sleeper 200 with the first damping member 210 disposed at the bottom, the damping values ​​of at least two of the first damping members 210 are different, so as to emit different sound levels when the wheels of the railway vehicle pass over different sleepers 200;

[0049] Among them, pitch refers to the sounds corresponding to different notes in the vocal music field. Taking the octave from C to the high C as an example, if 7 scales are selected, namely C, D, E, F, G, A, B, this is called the "C major scale". If C, D, D# (Eb), F, G, G# (Ab), A# (Bb) are selected, this is called the "C minor scale".

[0050] In addition, the tuning component further includes a plurality of first fasteners 410 arranged in the music area 110. The damping values of the first fasteners 410 are different from those of the second fasteners 420 arranged in the non-music area. Moreover, the damping values of at least two of the first fasteners 410 are different, and are used to emit different pitches when the wheels of the rail vehicle pass above different first fasteners 410.

[0051] For example, for the first fasteners 410 connecting the sleepers 200 and the rails 300 in the music area 110, the damping values corresponding to the first fasteners 410 at different positions are different, so that when the rail vehicle passes above different first fasteners 410, the pitches emitted by the first fasteners 410 due to vibration are different. And along the driving direction of the rail vehicle, according to the rhythm of the music and the pitch corresponding to each beat point, combined with the driving speed of the rail vehicle, the damping values of the corresponding first fasteners 410 are set, so as to convert the vibration sound into music when the rail vehicle travels in the music area 110.

[0052] Preferably, for the music track described in this embodiment, according to the rhythm of the music and the pitch corresponding to each beat point, combined with the driving speed of the rail vehicle, the damping values of the corresponding first fasteners 410 and the damping values of the first damping members 210 arranged at the bottoms of the corresponding sleepers 200 are set, so as to emit beautiful music when the rail vehicle travels in the music area 110. Since the pitches emitted by the rail vehicle when it travels to the first damping members 210 with different damping values are different from the pitches emitted by the rail vehicle when it travels to the first fasteners 410 with different damping values, different first damping members 210 with different damping values and different first fasteners 410 with different damping values can be combined and arranged in the music area 110 to emit music with more pitches.

[0053] For the music track described in this embodiment, by arranging a tuning component in the music area, including first damping members with different damping values arranged at the bottoms of different sleepers and first fasteners with different damping values arranged at different positions, when the rail vehicle travels in the music area, it can emit music with different pitches and corresponding rhythms, pleasing the physical and mental health of the passengers on the rail vehicle and preventing the boring noise from affecting the physical and mental health of the passengers and the surrounding residents.

[0054] Specifically, the first damping member 210 described in this embodiment includes at least one of a rubber pad, a spring damper, a hydraulic damper, and a viscous damper.

[0055] Among them, the damping value of the rubber pad can be adjusted by setting the thickness and hardness of the rubber pad.

[0056] Preferably, when setting the first fasteners 410 with different damping values, the damping values of the elastic fasteners of the multiple first fasteners 410 in the music area 110 are different. The elastic fastener is made of an elastic material into a strip shape and bent, and the damping value of the elastic fastener is adjusted by adjusting the elastic restoring force of the elastic fastener.

[0057] Specifically, there are at least two rails 300. In this embodiment, two rails 300 are taken as an example, and the two rails 300 are laid in parallel on the sleeper 200.

[0058] Specifically, in combination with Figure 3 As shown, one sleeper 200 is respectively connected to two rails 300 through two fasteners 400 on both sides. The damping values of the two first fasteners 410 connected to both ends of the sleeper 200 in the music area 110 are the same, so that the sound levels emitted at both ends are the same when the wheels of the rail vehicle pass over this sleeper 200.

[0059] Or, the damping values of the two first fasteners 410 connected to both ends of the sleeper 200 are different, so that the sound levels emitted at both ends are different when the wheels of the rail vehicle pass over this sleeper 200. When the wheels of the rail vehicle pass by, two sound levels are emitted simultaneously to emit a harmony.

[0060] Specifically, there are various distances between adjacent two tuning components in the music area 110, which are used to make the interval time lengths of the sound levels emitted different when the wheels of the rail vehicle pass over multiple sleepers.

[0061] Specifically, when the distances between adjacent tuning components in the music area 110 are all the same, the interval time lengths of the sound levels emitted when the rail vehicle passes over multiple tuning components are the same.

[0062] In this embodiment, for the change of the beat in the music, according to the running speed of the rail vehicle, the distance between adjacent tuning components in the music area 110 is determined to realize that corresponding sound levels are emitted at different interval time lengths when the rail vehicle passes by.

[0063] Furthermore, for the tuning component described in this embodiment, a plurality of second damping members 120 are further provided at the bottom of the roadbed 100. The plurality of second damping members 120 are arranged at intervals along the length direction of the roadbed 100. At least two of the plurality of second damping members 120 have different damping values, which are used to emit different sound levels when the wheels of the rail vehicle pass by.

[0064] Specifically, the first damping members 210 with different damping values, the second damping members 120 with different damping values, and the first fasteners 410 with different damping values can be arranged according to the order of a preset musical score, so as to emit more types of pitch levels when the rail vehicle is running.

[0065] Specifically, for a ballast bed, among the multiple second damping members 120 arranged at the bottom of the ballast bed, two adjacent second damping members 120 form a damping group 130. Figure 1 As shown, every two adjacent second damping members 120 constitute the damping group 130 described in this embodiment. The distances between the second damping members 120 of at least two of the multiple damping groups 130 are different, and are used to emit different interval durations of pitch levels when the wheels of the rail vehicle pass above the corresponding damping group 130, so as to match different beats and the changes of beats in the preset music.

[0066] Furthermore, for a ballast bed, the second damping member at the bottom of the ballast bed is in a plate-like structure, which can be a plate-like mechanism formed by a rigid damping device, or can be a soft damping device (such as a soft rubber pad) laid at the bottom of the ballast bed. The lengths of two adjacent second damping members along the running direction of the rail vehicle are various, and are used to emit different duration times of pitch levels when the wheels of the rail vehicle pass above the multiple second damping members.

[0067] Furthermore, when the track bed is a slab track bed, the bottom of the track is formed by seamless connection of multiple slab track beds. Second damping members are arranged at the bottom of the slab track bed, and the damping values of the second damping members at the bottoms of different slab track beds are different, so that different pitch levels are emitted when the rail vehicle runs on different slab track bed plates. It should be noted that since the slab track bed is an integral structure, when multiple second damping members with different damping values are arranged at the bottom of a single slab track bed, the pitch levels emitted when the rail vehicle runs on this slab track bed are the same. Therefore, the entire slab track bed is used as a tuning component, and different second damping members or combinations of multiple second damping members with different damping values are arranged at the bottoms of different slab track beds. Since the length of the slab track bed is about 10 meters, it is applicable to rail vehicles with relatively high speeds.

[0068] Specifically, the second damping member 120 described in this embodiment includes at least one of a rubber pad, a spring damper, a hydraulic damper, and a viscous damper. Preferably a rubber pad, and the damping value of the rubber pad is adjusted by setting the thickness and hardness of the rubber pad

[0069] Furthermore, the track bed 100 in this embodiment is formed by splicing multiple track bed units 140 along its length direction, and the lengths of at least two track bed units 140 in the music area 110 are different.

[0070] Combined with Figure 1As shown, the length of the roadbed unit 140 in the middle position is greater than the length of the roadbed unit 140 on the right. The rail vehicle will also make a separate sound when passing through the gap between the roadbed units 140. By arranging the roadbed units 140 with different lengths, the intervals at which the rail vehicle makes a sound when passing through the gaps between the roadbed units 140 are made different, so as to match different beats in the music.

[0071] Preferably, in addition to setting different elastic fastener damping values for the first fasteners 410, in combination with Figure 2 As shown, a third damping member 430 can also be provided on a plurality of first fasteners 410 within the music area 110; for the third damping members 430 provided on different first fasteners 410, at least two of the plurality of third damping members 430 have different damping values, so as to emit different pitch levels when the wheels of the rail vehicle pass above the corresponding third damping members 430.

[0072] Specifically, there are at least two rails 300. In this embodiment, two rails 300 are taken as an example, and the two rails 300 are laid parallel on the sleeper 200.

[0073] The sleeper 200 is connected to the two rails 300 through two fasteners 400 respectively. In the music area, the damping values of the third damping members 430 corresponding to the two first fasteners 410 connected to both ends of the sleeper 200 are the same, so that the pitch levels emitted at both ends when the wheels of the rail vehicle pass over this sleeper 200 are the same.

[0074] Alternatively, the sleeper 200 is connected to the two rails 300 through two first fasteners 410 respectively, and the damping values of the third damping members 430 corresponding to the two first fasteners 410 connected to both ends of the sleeper 200 are different, and different pitch levels are emitted at both ends when the wheels of the rail vehicle pass over this sleeper 200, so as to emit a harmony.

[0075] Specifically, the third damping member 430 described in this embodiment includes at least one of a rubber pad, a spring damper, a hydraulic damper, and a viscous damper. In combination with Figure 2 As shown, the third damping member 430 is sleeved on the bolt of the third damping member 430.

[0076] Preferably, on the basis of the above implementation manner, this embodiment further provides a music track design method. In combination with Figure 4 As shown, it includes the following steps:

[0077] Step S100, determine the pitch level corresponding to each time point in the preset music, and the interval duration between two adjacent pitch levels;

[0078] Specifically, preset music is set in the music area of the track. Based on the music score corresponding to the preset music, the interval duration between two adjacent pitch classes is determined according to the beats on the music score. When the preset music is played, the corresponding pitch classes are played at different time points. After determining the interval duration between adjacent pitch classes and the corresponding pitch classes, the corresponding pitch classes are played at the corresponding time points, and thus the preset music can be played.

[0079] Step S200: Determine the music area of the track and the speed of the track vehicle corresponding to the music area.

[0080] The music area is determined on the track, preferably at positions such as tourist attractions, residential areas or stations. And the speed of the track vehicle corresponding to when the track vehicle travels to the music area is determined through the track vehicle control center.

[0081] Step S300: Determine the distance between adjacent tuning components in the music area according to the product of the speed and the interval duration.

[0082] Specifically, when the running speed of the track vehicle in the music area and the interval duration between two adjacent pitch classes in the preset music are obtained, the running speed and the interval duration are multiplied to obtain the distance between two adjacent tuning components.

[0083] For example, if the running speed of the track vehicle is 150 km / h and the interval durations between 8 adjacent pitch classes in a certain audio segment of the preset music are 0.5 seconds, 0.5 seconds, 0.5 seconds, 1 second, 0.5 seconds, 0.5 seconds and 0.5 seconds respectively, then the distances between the corresponding 8 tuning components are 25 meters, 25 meters, 25 meters, 50 meters, 25 meters, 25 meters and 25 meters respectively, so as to emit the corresponding pitch classes when the track vehicle travels to the corresponding tuning components and match the beats of the preset music.

[0084] Step S400: Determine the different pitch classes corresponding to when the wheels of the track vehicle pass through the tuning components with different damping values at the speed.

[0085] Specifically, different pitch classes of the first damping member 210 with different damping values and different pitch classes of the first fastener 410 with different damping values are obtained through experiments.

[0086] Step S500: Determine the damping values of the tuning components in the music area according to each pitch class in the preset music.

[0087] For the pitch classes required at different positions in the music area 110, it is selected whether to set the first damping member 210 with the corresponding damping value under the sleeper 200 at the corresponding position or to select the first fastener 410 with the corresponding damping value at the sleeper 200 at the corresponding position.

[0088] It should be noted that the order of the steps of the music track design method described in this embodiment can be swapped. For example, step S400 can be before step S300. The order of the steps described in this embodiment does not limit that the music track design method of the present invention can only be executed in the order of the steps described in this embodiment.

[0089] Specifically, on the basis of the above-mentioned implementation manner, this embodiment further provides a music track design device for implementing the music track design method described above.

[0090] Specifically, it includes an acquisition module, a calculation module, and a processing module.

[0091] The acquisition module is used to acquire the music score of the preset music. The acquisition module can acquire the music score of the preset music from the Internet or acquire the music score transmitted by the operator through a storage device, and then the acquisition module transmits the music score to the processing module.

[0092] The acquisition module is also used to acquire the speed of the rail vehicle corresponding to the music area. The acquisition module can acquire the rail vehicle operation record data or the designed speed data in the database of the rail transit to obtain the speed of the rail vehicle corresponding to the music area; it can also acquire the speed of the rail vehicle input by the operator through an input device, and then the acquisition module transmits the music score to the processing module.

[0093] The acquisition module is also used to acquire the different pitch levels corresponding to the rail vehicle passing through the tuning components with different damping values at the corresponding speed; specifically, first obtain the pitch levels emitted by the tuning components with different damping values through previous experiments, and input the corresponding matching data into the acquisition module through a storage device or an input device, and then the acquisition module transmits the acquired data to the processing module.

[0094] The processing module is used to determine the pitch level corresponding to each time point in the preset music according to the music score, and the interval duration between two adjacent pitch levels; the processing module acquires the pitch level of each beat in chronological order and arranges them in chronological order.

[0095] The calculation module is used to calculate the product of all the interval durations and the speed according to the speed and the interval duration.

[0096] The processing module is used to determine the distance between adjacent tuning components in the music area according to the product of the interval duration and the speed, and determine the damping value of the tuning components in the music area according to each pitch level in the preset music.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
