摘要： PROBLEM TO BE SOLVED: To carry out fine control without any increase in the number of control stages for a coefficient of attenuation in a variable attenuation damper as a single body, in a roll damping system, in which a multistage throttle switching type variable attenuation damper is used, for a railway rolling stock. SOLUTION: Multistage throttle switching type variable attenuation dampers 3, 4 based on a high speed solenoid valve are paired with each other so as to be arranged between a carriage 1 and a rolling stock body 2, and according to the on/off operation of the high speed solenoid valve by means of a computer 40, combination of throttles in each of the variable attenuation dampers 3, 4 is selected, so that a coefficient of attenuation is controlled as a total, or control phases of the variable dampers 3, 4 are deflected from each other by means of the computer 40. At the same time, the coefficient of attenuation is subtracted while the coefficient of attenuation for either of the variable attenuation dampers 3, 4, which are controlled in the previous cycle, is maintained, and relative roll between the carriage 1 and the rolling stock body 2 is damped while the coefficient of attenuation for either of the variable attenuation dampers 3, 4 in the following cycle is controlled.

摘要： PURPOSE: To provide a roll damping damper suitable for the use in a rolling stock, in which the mass of the car body or an object on the damping side is huge. CONSTITUTION: A control damper 3 (4) is constituted of a stroke sensing cylinder of a unidirectional flow type, a damping force controlling circuit, and an unload valve for both expansion and contraction sides, all of which are interposed between a truck 1 and a car body 2. Moreover, the car body 2 is provided with a detector 5 for detecting the lateral deflection. By using car speed signals U1, U2 from the detector 5, the direction of the deflection is judged by a computer, and the unload valve for both expansion and contraction sides is selectively switched for control, inversely corresponding to the expanding/contracting action of the control damper 3 (4). By using displacement signals W1, W2 and damper speed signals V1, V2, which are figured out from W1, W2, together with the car speed signals U1, U2, the generated, damping force in a damping force controlling circuit is controlled by the computer.

摘要： PURPOSE: To provide a lateral oscillation damper suitably used for rolling stock in which the mass of a body to be the damping side is extremely large. CONSTITUTION: Control dampers 3, 4 are constituted of unidirectional flow stroke sensing cylinders interposed between a truck 1 and a body 2, a damping force control circuit, and expanding side and pressing side unloading valves, and lateral oscillation detector 5 is installed at the body 2.

摘要： PURPOSE: To obtain a vibration level gauge (comfortability level measuring apparatus) which can be reproduced easily, stably and accurately over a wide frequency range. CONSTITUTION: The vibration level gauge 1 comprises a vibration sensor 2, a converter 3 for converting a vibration signal from the sensor 2 into a digital amount, a digital filter 5 performing frequency correction corresponding to the vibration feeling of human being, and an operating section 6 for calculating a normalized vibration level based on an output from the digital filter 5. Since the frequency correction corresponding to the vibration feeling of human being and subsequent processing can be subjected to digital signal processing at the digital filter and the operating section, an accurate data can be obtained surely and easily without requiring any intricate operation or troublesome maintenance and a single gauge can deal with a wide frequency range flexibly.

摘要： PROBLEM TO BE SOLVED: To provide an articulated vehicle testing arrangement which is compact and precisely simulates the running state of an articulated vehicle.
SOLUTION: A frame assembly (30 and 50) includes a front vehicle end face (50a) opposite to an articulated part (3a) and is given a reference axis (57a) parallel to the front vehicle end face (50a). The frame assembly (30 and 50) is supported by a link support means (12), while the movement of the front vehicle end face (50a) is limited to a prescribed degree of freedom. The frame assembly (30 and 50) is engaged with a rise-and-fall/roll driving means (41) which moves the frame assembly so that the reference axis (57a) moves along the vertical direction and tilts therefrom, a rotation driving means (42) which moves the assembly so that the front vehicle end face (50a) is rotated around the reference axis (57a), and a horizontal driving means (40) which moves the assembly so that the reference axis (57a) is shifted horizontally in almost parallel to the front vehicle end face (50a). A load detecting means which detects loads on the rise-and-fall/roll driving means (41), the rotation driving means (42) and the horizontal driving means (40) is provided so as to conduct measurement.

摘要： PURPOSE:To ensure a required moving amount by employing a double stage link mechanism for supporting a pantograph, extending the link into the body and additionally providing a deadweight at the lower end of the link, thereby taking advantage of excessive centrifugal force functioning on both the pantograph and the deadweight at the time of traveling on a curve. CONSTITUTION:A pair of links 3 are provided, while being supported at two points, in a body 2 and a deadweight 4 is fixed to the lower end of the link 3. The link 3 and the deadweight 4 are disposed symmetrically in the center of the body 2 where the links 3, disposed on the opposite sides, are coupled through a support 5 above the body 2 and a pantograph 1 is disposed in the center of the support 5. According to the constitution, the pantograph 1 moves oppositely to the inclination of the body 2 when the body 2 inclines inwardly at a curve and thereby relative movement of collector shoe and stringing is suppressed in lateral direction. Furthermore, the link 3 is provided with a damper 6 for absorbing transient vibration in order to suppress unnecessary lateral movement due to incorrect track.

摘要： PURPOSE:To increase gravitational restoring force, and to prevent weaving creak, and wear of rails, when the wheels move right and left from the neutral position to the rails more than a prescribed value, by forming the tread surface in such a way that the difference between the angles made by the tangential lines at the points where the respective right and left wheel tread surfaces are in contact with the top surfaces of the rail heads and by the horizontal surface becomes greater than a prescribed value. CONSTITUTION:The tread surface is formed in such a way that the difference between the angles alphaR, alphaL formed by the tangential lines at the contact points AR, AL for determining the right and left directional component forces QR, QL of the normal forces NR, NL and by the horizontal surface becomes more than 0.1 rad, when right and left wheels 2, 3 move right and left more than 2 mm, while the respective wheels 2, 3 are in contact with the head surfaces 4 of rails 1 at contact points AR, AL.Thereby the gravitational restoring force Y to be obtained by the difference QR-QL between the right and left component forces QR, QL can be increased. By this constitution, weaving, wear of rails, and creak at the passage of a curve can be prevented, and also weight can be reduced.
