Description
本発明は、鉄道車両の乗心地を向上する車体間ダンパ装置を備える編成車両に関する。
The present invention relates to a knitted vehicle including a vehicle body damper device that improves the riding comfort of a railway vehicle.
近年、鉄道車両の高速化に伴い、曲線通過時に生じるロール振動（車両の長手方向に沿う軸周りの振動）や、上下方向の車体曲げ振動、車体のヨー振動（水平面内の振動）等が顕在化して乗心地が劣化する傾向があるため、これらの振動を抑制して、乗心地を向上することが求められる。そこで、車両と車両との連結部に、車両間に架け渡される複数のダンパから構成される車体間ダンパ装置を備えることによって、振動を抑制するとともに乗心地を向上している。
In recent years, with the speeding up of railway vehicles, roll vibration (vibration around the axis along the longitudinal direction of the vehicle), vertical body bending vibration, body yaw vibration (vibration in a horizontal plane), etc., have become apparent. Therefore, it is required to improve the riding comfort by suppressing these vibrations. Therefore, by providing an inter-vehicle body damper device composed of a plurality of dampers bridged between the vehicles at the connecting portion between the vehicles, vibration is suppressed and riding comfort is improved.
このような車体間ダンパ装置の例として、連結された車体間において貫通路の両側に、車両間に上下方向に一対の上下ダンパを架け渡して、連結された車体間に生じる上下相対速度に対して減衰力を発生させることで、車体の長手方向の端部の上下振動を抑制するとともに曲げ振動を防止する車体間ダンパ装置が提案されている。（例えば、特許文献１参照）。
As an example of such an inter-vehicle damper device, a pair of upper and lower dampers are bridged in the vertical direction between vehicles on both sides of the through-passage between the connected vehicle bodies, and relative to the vertical relative speed generated between the connected vehicle bodies. Thus, there has been proposed an inter-vehicle damper device that suppresses vertical vibrations at the ends of the longitudinal direction of the vehicle body and prevents bending vibrations by generating a damping force. (For example, refer to Patent Document 1).
鉄道車両が高速で走行する際に、軌道の上下方向の不整に起因して、車体を支持する後台車が上下方向に振動する。この結果、上下方向に振動する台車に支持される車体も、台車によって上下方向に加振されることになり、車体に曲げ振動が発生する。
When the railway vehicle travels at a high speed, the rear carriage supporting the vehicle body vibrates in the vertical direction due to irregularities in the vertical direction of the track. As a result, the vehicle body supported by the cart that vibrates in the vertical direction is also vibrated in the vertical direction by the cart, and bending vibration is generated in the vehicle body.
この車体の曲げ振動の固有周波数は、人間が不快を感じやすい周波数帯域に近いため、上下方向の乗心地の悪化の原因となりやすい。また、鉄道車両が高速で曲線を通過する際には、軌道に設けられたカントや軌道不整によって、車体がロール方向に振動するため、乗心地の悪化の原因となりやすい。
This natural frequency of bending vibration of the vehicle body is close to a frequency band in which humans are likely to feel uncomfortable, so it tends to cause deterioration in riding comfort in the vertical direction. Further, when a railway vehicle passes through a curve at a high speed, the vehicle body vibrates in the roll direction due to a cant provided on the track or an irregular track, which is likely to cause a deterioration in riding comfort.
前述した特許文献１で提案されている車体間ダンパ装置は、連結された２つの車体間に上下方向に架け渡されるため、車体の曲げ振動および車体のロール方向の振動の低減には有効である。

しかしながら、特許文献１に係る車体間ダンパ装置は、左右方向の軌道不整により発生する車体の左右振動および車体のヨー方向の振動に対応する減衰力を発生しないので、ヨー方向の振動を低減できるダンパを追設する必要がある。しかしながら、上下方向および左右方向の軌道不整等に起因する振動を抑制するためには、車体間に架け渡されるダンパの数を増やすことが有効であるが、ダンパの数が増えると製造コストおよびダンパに係る保守コストを大きくするおそれがあるため、ダンパの数は大きくないことが望ましい。
However, since the inter-vehicle damper device according to Patent Document 1 does not generate a damping force corresponding to left-right vibration of the vehicle body and vibration in the yaw direction of the vehicle body caused by a trajectory irregularity in the left-right direction, the damper capable of reducing vibration in the yaw direction. Need to be added. However, it is effective to increase the number of dampers bridged between the vehicle bodies in order to suppress vibrations caused by vertical and horizontal trajectory irregularities. However, as the number of dampers increases, the manufacturing cost and the dampers increase. Therefore, it is desirable that the number of dampers is not large.
本発明は、以上の点を考慮してなされたものであり、ダンパの数を小さくしてダンパに係る製造および保守コストを低減するとともに、車体の曲げ振動や車体のヨー（左右）方向およびロール方向の振動を効果的に抑制して乗心地を向上できる車体間ダンパ装置を備える編成車両を提供することを目的とする。

図６は、高速で走行する編成車両の第１中間車両から第３中間車両が上下方向に振動する様子を側面視で示した模式図である。編成車両１が高速で走行する際、上下方向の軌道不整等によって、台車５５は上下方向に振動する。上下方向に振動する台車５５に支持される第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃは、台車５５によって上下方向に加振されて曲げ振動が生じる。
FIG. 6 is a schematic diagram showing a side view of the manner in which the third intermediate vehicle vibrates in the vertical direction from the first intermediate vehicle of the knitted vehicle running at high speed. When the knitting vehicle 1 travels at a high speed, the carriage 55 vibrates in the vertical direction due to irregular track in the vertical direction. The first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c supported by the cart 55 that vibrates in the vertical direction are vibrated in the vertical direction by the cart 55 to cause bending vibration.
連結された複数の中間車両に生じる曲げ振動には２種類の曲げ振動モードがある。一方の曲げ振動モードは、第２中間車両３０ｂの長手方向中央部が上方向に変位して、第１中間車両３０ａおよび第３中間車両３０ｃの長手方向の中央部が下方向に変位するような前後の車両間に位相差がある曲げ振動（図６参照）である。他方の曲げ振動モードは、第２中間車両３０ｂ、第１中間車両３０ａおよび第３中間車両３０ｃの長手方向の中央部が同方向に変位するような前後の車両間で位相差の無い（同位相）の曲げ振動である（図示なし）。
There are two types of bending vibration modes in bending vibrations that occur in a plurality of connected intermediate vehicles. One bending vibration mode is such that the longitudinal middle portion of the second intermediate vehicle 30b is displaced upward, and the longitudinal middle portions of the first intermediate vehicle 30a and the third intermediate vehicle 30c are displaced downward. This is a bending vibration (see FIG. 6) having a phase difference between the front and rear vehicles. The other bending vibration mode has no phase difference between the front and rear vehicles in which the central portions in the longitudinal direction of the second intermediate vehicle 30b, the first intermediate vehicle 30a, and the third intermediate vehicle 30c are displaced in the same direction (the same phase ) Bending vibration (not shown).
図６に示す隣接する車両の中央部が異なる方向に変位する位相差を有する場合の振動低減の作用および効果を説明する。点線３００ａ、３００ｂおよび３００ｃは、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃの各々が曲げ振動に伴って変形する様子を模式的に示したものである。隣接する中間車両の間で位相差を伴う曲げ振動の場合、第２中間車両３０ｂの前後方向の両端部に下方向の速度が発生するとともに、第１中間車両３０ａの後側端部および第３中間車両３０ｃの前側端部に上方向の速度が発生する。
The operation and effect of vibration reduction in the case where the central part of adjacent vehicles shown in FIG. 6 has a phase difference that is displaced in different directions will be described. Dotted lines 300a, 300b, and 300c schematically show how the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c are deformed in accordance with bending vibration. In the case of bending vibration with a phase difference between adjacent intermediate vehicles, a downward speed is generated at both ends in the front-rear direction of the second intermediate vehicle 30b, and the rear end portion of the first intermediate vehicle 30a and the third end An upward speed is generated at the front end of the intermediate vehicle 30c.
この結果、第２車体間ダンパ装置Ａ２の上下ダンパ４ｂおよび第３車体間ダンパ装置Ａ３の上下ダンパ４ａは、上下方向に伸縮する相対速度が生じるとともにこの相対速度を打ち消す方向の減衰力６６を生じる。上下ダンパ４ａ（４ｂ）の減衰力６６によって、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃの上下方向の振動が抑制されるため、ダンパの数を小さくしてダンパに係る製造および保守コストを低減するとともに、乗心地を高めることができる。
As a result, the upper and lower dampers 4b of the second inter-vehicle damper device A2 and the upper and lower dampers 4a of the third inter-vehicle damper device A3 generate a relative speed that expands and contracts in the vertical direction, and a damping force 66 that cancels the relative speed. . The damping force 66 of the upper and lower dampers 4a (4b) suppresses vertical vibrations of the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c. Manufacturing and maintenance costs can be reduced, and riding comfort can be increased.
図７は、高速で走行する編成車両の第１中間車両から第３中間車両（図１Ｄ部相当）が左右方向およびヨー方向に振動する様子を上面視で示した模式図である。編成車両１が高速で走行する際、左右方向の軌道不整等により、台車５５は左右方向に振動する。その結果、左右方向に振動する台車５５に支持される第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃの各車体は、台車５５によって左右方向に加振されて左右振動およびヨー方向に振動する。
FIG. 7 is a schematic view showing a top view of a state in which the first intermediate vehicle to the third intermediate vehicle (corresponding to the portion shown in FIG. 1D) of the knitted vehicle running at high speed vibrates in the left-right direction and the yaw direction. When the knitting vehicle 1 travels at a high speed, the carriage 55 vibrates in the left-right direction due to an irregular track in the left-right direction. As a result, the vehicle bodies of the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c supported by the cart 55 that vibrates in the left-right direction are vibrated in the left-right direction by the cart 55, and the left-right vibration and yaw. Vibrate in the direction.
図７に示す点線３１０ａ、３１０ｂおよび３１０ｃは、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃの各々のヨー方向の振動９０を模式的に示したものである。第１中間車両３０ａの後端部が右側７８に振動し、第２中間車両３０ｂの前端部が左側７９に振動する様子を示している。同様に、第２中間車両３０ｂの後端部が右側７８に振動し、第３中間車両３０ｃの前端部が左側７９に振動する様子を示している。
7 schematically show the vibrations 90 in the yaw direction of the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c. The state where the rear end portion of the first intermediate vehicle 30a vibrates to the right side 78 and the front end portion of the second intermediate vehicle 30b vibrates to the left side 79 is shown. Similarly, the rear end portion of the second intermediate vehicle 30b vibrates to the right side 78, and the front end portion of the third intermediate vehicle 30c vibrates to the left side 79.
図７に示す態様で編成車両１をなす各車両がヨー方向に振動すると、第２車体間ダンパ装置Ａ２の左右ダンパ８および第３車体間ダンパ装置Ａ３の左右ダンパ８に、左右方向に伸縮する相対速度が生じるため、左右ダンパ８に相対速度（左右方向の振動およびヨー方向の振動９０）を打ち消す方向の減衰力６６を生じて、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃの左右方向の振動に起因するヨー方向の振動を低減してダンパの数を小さくしてダンパに係る製造および保守コストを低減するとともに、乗心地を向上することができる。
When each vehicle constituting the formation vehicle 1 in the form shown in FIG. 7 vibrates in the yaw direction, the left and right dampers 8 of the second inter-vehicle damper device A2 and the left and right dampers 8 of the third inter-vehicle damper device A3 expand and contract in the left-right direction. Since the relative speed is generated, a damping force 66 is generated in the left and right dampers 8 in a direction that cancels the relative speed (vibration in the left-right direction and vibration 90 in the yaw direction), and the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate The vibration in the yaw direction caused by the vibration in the left-right direction of the vehicle 30c can be reduced to reduce the number of dampers, thereby reducing manufacturing and maintenance costs related to the dampers, and improving riding comfort.
図８は、高速で走行する編成車両の第２車体間ダンパ装置と第３車体間ダンパ装置を編成車両の長手方向に重ねるとともに、ロール方向に隣接する車両が振動の様子を示した模式図である。
FIG. 8 is a schematic diagram showing a state in which the second inter-body damper device and the third inter-body damper device of the knitted vehicle traveling at high speed are stacked in the longitudinal direction of the knitted vehicle, and the vehicle adjacent to the roll direction vibrates. is there.
編成車両１が高速で曲線を通過する際、軌道に設けられたカントや軌道不整等により、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃがその長手方向に沿う軸周り（ロール方向）に振動する。
When the formation vehicle 1 passes through the curve at a high speed, the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c are about the axis along the longitudinal direction due to the cant provided on the track, the track irregularity, etc. Vibrates in the roll direction).
図８に示す点線は、第２中間車両３０ｂがロール方向に振動する様子を模式的に示したものであり、一点鎖線は第１中間車両３０ａおよび第３中間車両３０ｃを示す。第２中間車両３０ｂおよび先頭車両２０にロール方向の振動（変位）９１が生じると、隣接する第１中間車両３０ａおよび第３中間車両３０ｃとの間にロール方向の相対変位が発生して、第２車体間ダンパ装置Ａ２の上下ダンパ４ｂと左右ダンパ８および第３車体間ダンパ装置Ａ３の上下ダンパ４ａと左右ダンパ８がロール変位に応じて伸縮する。
8 schematically shows how the second intermediate vehicle 30b vibrates in the roll direction, and the alternate long and short dash lines indicate the first intermediate vehicle 30a and the third intermediate vehicle 30c. When a roll direction vibration (displacement) 91 occurs in the second intermediate vehicle 30b and the leading vehicle 20, a relative displacement in the roll direction occurs between the adjacent first intermediate vehicle 30a and the third intermediate vehicle 30c. The upper and lower dampers 4b and the left and right dampers 8 of the two inter-vehicle damper device A2 and the upper and lower dampers 4a and the left and right dampers 8 of the third inter-vehicle damper device A3 expand and contract according to the roll displacement.
この時、上下ダンパ４ａ（４ｂ）と左右ダンパ８は、相対速度に応じたロール方向の振動９１に抗する方向に減衰力６６を発生するため、第２中間車両３０ｂのロール方向の振動９１を抑制して乗心地を向上することができる。
At this time, the upper and lower dampers 4a (4b) and the left and right dampers 8 generate the damping force 66 in a direction against the vibration 91 in the roll direction corresponding to the relative speed, and therefore the vibration 91 in the roll direction of the second intermediate vehicle 30b. It is possible to suppress and improve riding comfort.
また、第２中間車両３０ｂの前側に備えられる第２車体間ダンパ装置Ａ２の上下ダンパ４ｂと、その後側の第３車体間ダンパ装置Ａ３の上下ダンパ４ａは、車体の幅方向に交差する中心線Ｃを含む面に対して対角に備えられる。
In addition, the upper and lower dampers 4b of the second inter-vehicle damper device A2 provided on the front side of the second intermediate vehicle 30b and the upper and lower dampers 4a of the rear third inter-vehicle damper device A3 intersect with each other in the width direction of the vehicle body. Provided diagonally to the plane containing C.
このため、第１中間車両３０ａと第２中間車両３０ｂと第３中間車両３０ｃにロール方向の振動９１が生じる場合であっても、上下ダンパ４ｂに生じる上向きの減衰力６６と、上下ダンパ４ａに生じる下向きの減衰力６６が相殺されるため、ロール方向の振動９１に伴う減衰力６６が、第１中間車両３０ａから第３中間車両３０ｃを上下方向に加振しないので、この減衰力６６に伴う曲げ振動が生じにくい。
For this reason, even when vibration 91 in the roll direction occurs in the first intermediate vehicle 30a, the second intermediate vehicle 30b, and the third intermediate vehicle 30c, the upward damping force 66 generated in the upper and lower dampers 4b and the upper and lower dampers 4a. Since the generated downward damping force 66 is canceled, the damping force 66 accompanying the vibration 91 in the roll direction does not vibrate the third intermediate vehicle 30c from the first intermediate vehicle 30a in the vertical direction. Bending vibration hardly occurs.
したがって、ロール方向の振動に誘発される上下方向の振動の発生を抑制することができるため、ダンパの数を小さくしてダンパに係る製造および保守コストを低減するとともに、乗心地を向上することができる。
Therefore, since it is possible to suppress the occurrence of vertical vibration induced by vibration in the roll direction, it is possible to reduce the number of dampers and reduce manufacturing and maintenance costs related to the dampers, and improve riding comfort. it can.
また、先頭車両２０と第１中間車両３０ａとの間および第３中間車両３０ｃと後尾車両４０との間に備えられる第１車体間ダンパ装置Ａ１は、一対の上下ダンパ４ａ（４ｂ）を有するので、ロール方向の振動が上下方向の振動に転換されることを低減することができる。したがって、このため、ロール方向の振動に誘発される上下方向の振動の発生を抑制することができるため、乗心地を向上することができる。
The first inter-vehicle damper device A1 provided between the leading vehicle 20 and the first intermediate vehicle 30a and between the third intermediate vehicle 30c and the trailing vehicle 40 includes a pair of upper and lower dampers 4a (4b). The vibration in the roll direction can be reduced from being converted into the vibration in the vertical direction. Therefore, since it is possible to suppress the occurrence of vertical vibration induced by vibration in the roll direction, it is possible to improve riding comfort.
なお、実施形態１では、一対の上下ダンパ４ａ（４ｂ）を有する第１車体間ダンパ装置Ａ１を先頭車両２０と第１中間車両３０ａとの連結部、あるいは第３中間車両３０ｃと後尾車両４０との連結部に備える例を示した。第１車体間ダンパ装置Ａ１は、編成車両の両端部の車両と、その車両に連結する中間車両との連結部に限定されず、例えば、より快適な乗心地が要求される一等（中間）車両または屋根上に搭載される集電装置に作用する流体力によって乗心地が劣化しやすい中間車両と、これら中間車両に連結する他の中間車両との連結部に備えても良い。
In the first embodiment, the first inter-vehicle damper device A1 having the pair of upper and lower dampers 4a (4b) is connected to the connecting portion between the leading vehicle 20 and the first intermediate vehicle 30a, or the third intermediate vehicle 30c and the rear vehicle 40. The example with which the connection part of is provided was shown. The first inter-vehicle damper device A1 is not limited to a connection portion between the vehicles at both ends of the formation vehicle and an intermediate vehicle connected to the vehicle, for example, the first (intermediate) that requires a more comfortable riding comfort. You may provide in the connection part of the intermediate vehicle from which riding comfort deteriorates easily with the fluid force which acts on the current collector mounted on a vehicle or a roof, and the other intermediate vehicle connected with these intermediate vehicles.
また、実施形態１では、第１車体間ダンパ装置Ａ１、第２車体間ダンパ装置Ａ２および第３車体間ダンパ装置Ａ３は、左右ダンパ８を貫通路５０の上方に備える例を示したが、これに限らず、左右ダンパ８を貫通路５０の下方に備えても良い。
In the first embodiment, the first inter-vehicle damper device A1, the second inter-vehicle damper device A2, and the third inter-vehicle damper device A3 are provided with the left and right dampers 8 above the through passage 50. However, the left and right dampers 8 may be provided below the through passage 50.
高速で走行する車両は、後尾車両４０の下流に大きな渦を伴う気流の乱れが生じやすく、この気流の乱れに伴う圧力変動によって、後尾車両が左右方向に振動する場合がある。このため、第１車体間ダンパ装置Ａ１は１対（２本）の前後ダンパ７ａ（７ｂ）を備えることによって、この左右方向の振動を抑制して乗心地を高めている。第２車体間ダンパ装置Ａ２および第３車体間ダンパ装置Ａ３は、大きな圧力変動を受けるおそれの小さい中間車両の間に備えられるため、前後ダンパ７ａ（７ｂ）を省略しても良い。
A vehicle traveling at a high speed is likely to be disturbed by an air current with a large vortex downstream of the tail vehicle 40, and the tail vehicle may vibrate in the left-right direction due to pressure fluctuations associated with the air current disturbance. For this reason, the first inter-vehicle damper device A1 includes a pair of (two) front and rear dampers 7a (7b), thereby suppressing the vibration in the left-right direction and improving the riding comfort. Since the second inter-vehicle damper device A2 and the third inter-vehicle damper device A3 are provided between intermediate vehicles that are unlikely to receive large pressure fluctuations, the front and rear dampers 7a (7b) may be omitted.

As in the case of the first embodiment, the knitted vehicle including the inter-vehicle body damper device according to the second embodiment reduces the number of dampers to reduce the manufacturing and maintenance costs related to the dampers, as well as the bending vibration of the vehicle body and the roll direction. Vibration can be reduced, and left-right vibration of the vehicle body and vibration in the yaw direction can be reduced to further improve the riding comfort of the vehicle.
これに加えて、実施形態２では、上下ダンパ４ｂを、妻板の一方の側にのみ備えるため、製造時に上下ダンパ４ｂを取付けたり、保守作業時に点検したり交換したりする場合に、作業者は上下ダンパ４ｂを編成車両１の一方の側のみから取り扱うことができるため、製造および作業効率を向上することができる。
In addition, in the second embodiment, since the upper and lower dampers 4b are provided only on one side of the end plate, when the upper and lower dampers 4b are attached at the time of manufacture, or inspected or replaced during maintenance work, Since the upper and lower dampers 4b can be handled only from one side of the knitted vehicle 1, manufacturing and work efficiency can be improved.
