    • PROBLEM TO BE SOLVED: To provide a rail vehicle having a sound absorbing structure capable of reducing the manufacturing cost and increasing the sound absorbing ratio in an objective frequency band.
      SOLUTION: A second sound absorbing material 20 is laminated on a first sound absorbing material 15, the surface area of the sound absorbing material exposed to the noise generated in an underfloor wheel chamber is increased corresponding to a peripheral surface part of the second sound absorbing material 20, and a top part 50a of a fixing tool 50 located in a vicinity of the increased surface area is functioned as a sound reflecting member. Thus, the ratio of the sound wave which is reflected by the reflecting member, and then, incident on the sound absorbing material and absorbed (damped) thereby is increased, and the sound absorbing ratio in the frequency band between f1 and f2 can be increased. Further, the entire thickness (the height in the vertical direction) of the sound absorbing material to a frame 18 for giving the sound source side surface of a rail vehicle is increased, and the sound absorbing ratio of the low frequency band can be increased. While suppressing the increase in the number of components as much as possible, the increase of the manufacturing cost is minimized, and the sound absorbing ratio in the frequency band for the sound absorption can be increased.

    • 要解决的问题:提供一种具有能够降低制造成本并增加目标频带中的吸声率的吸音结构的轨道车辆。 解决方案:第一吸音材料20层叠在第一吸音材料15上,暴露于地板车室内产生的噪音的吸音材料的表面积相应于第二吸音材料的外周表面部分增加 吸音材料20和位于增加表面积附近的固定工具50的顶部50a用作声音反射部件。 因此,由反射构件反射然后入射到吸声材料上并被吸收(阻尼)的声波的比例增加,并且可以增加f1和f2之间的频带中的吸声比 。 此外,吸声材料与用于给轨道车辆的声源侧表面的框架18的整个厚度(垂直方向的高度)增加,并且可以增加低频带的吸声率。 虽然尽可能地抑制部件数量的增加,但是制造成本的增加被最小化,并且可以增加用于吸声的频带中的吸声率。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To improve riding comfort of passengers by compensating an inclination to the outside of a curve in a loss of riding comfort of passengers, the loss being raised by flexure of an air spring supporting a vehicle body with a centrifugal force applied to the vehicle body when a railway vehicle with a vehicle body inclining device passes through a curve, which inclines the vehicle body outside the curve, and reduces the inclination angle to be essentially targeted by the vehicle inclining device by the inclination.
      SOLUTION: Prior to entering a curve and going out from the curve, a control device 9 controls a vehicle body inclination compensating intake/exhaust valve 10 based on a traveling position of the vehicle and curve information, so as to supply or exhaust compressed air in an air spring 2 in a direction for compensating the flexure before the air spring 2 is flexed.

    • PROBLEM TO BE SOLVED: To improve riding comfort by obtaining a required inclination angle of a car body at the time of traveling at a curved track, and reducing oscillation transmitted from a bogie to the car body through actuators at the same time. SOLUTION: The actuators 13, 14 having displacement regulating members 11, 12 are fixed and supported at the bogie 2, and a displacement regulating member receiving 10 is fixed at the car body between the car body 1 and the bogie 2. The displacement regulating members are brought into contact with the displacement regulation member receiving by the actuators so that a car body inclination motion command from a control device 24 may incline the car body in a direction reverse to a centrifugal force of the curved track during traveling of the car. Therefore, the required inclination angle of the car body can be obtained completely, feeling crosswise acceleration can be reduced, and riding comfort can be improved. Besides, a gap is obtained between the displacement regulation members and the displacement regulation member receiving at the time of the traveling at a straight track at least, and the oscillation and force transmitted to the car body can be eliminated, thus improving the riding comfort.

    • PROBLEM TO BE SOLVED: To propose a sloping device with a light-weight sloping mechanism, which is able to secure ride quality of passengers on both sides.
      SOLUTION: A vehicle body 8 is supported on a wagon frame 4 through aerial springs 5. A torsion bar is loaded on the wagon frame 4 in the cross direction of the vehicle body 8. Links 15L and 15R sloping to the inside of the vehicle body 8 at both end of the torsion bar 11 through levers 13 and 13. The upper end of the links are connected to the vehicle body 8. Thus, a rolling variation at both end of the vehicle body 8 is constrained, and deficiency of sloping angle of the links 15 is solved with its structure, which does not constrain ups and downs variation of the same phase when running on a short trajectory route as well. Occurrence of excess centrifugal acceleration, which works on the vehicle body 8, ensures proper operation of vehicle body sloping by a link mechanism. Thus, the rail road vehicle can be realized in lightweight and at reasonable cost.
