摘要： PROBLEM TO BE SOLVED: To provide an acceleration-detecting apparatus which can easily detect a failure. SOLUTION: A pair of acceleration sensors provided at an acceleration- detecting apparatus main body 1 are arranged with respective sensitivity axes inclined by inclination angles θA, θB to a horizontal axis H. An output signal α1 corresponding to a horizontal acceleration αH and an output signal α2 corresponding to a vertical acceleration αV are operated at an operation circuit. When an object an acceleration of which is to be detected stands still, the output signal α2 corresponding to the vertical acceleration αV is compared with the vertical acceleration αV which is to be obtained at the normal time because of a gravitational acceleration, so that a failure of the acceleration- detecting apparatus is detected.

摘要： PROBLEM TO BE SOLVED: To provide a vibration-isolating device and a vibration-isolating method for a railroad vehicle capable of reducing the possibility of occurrence of a derailment of the vehicle or the like when an earthquake occurs, and enhancing the ride quality of the vehicle in a normal state.
SOLUTION: The railroad vehicle vibration-isolating device controls the damping force of damping elements (a shaft damper 31, a right-to-left movable damper 17, an air spring 15, etc.) by a ride quality priority mode controller A1 focusing on the enhancement of the ride quality of a vehicle 1. When an earthquake is detected by an earthquake detection means 45, the controller is changed to an earthquake-mode controller A2 focusing on derailment prevention by a controller changing means 41, and the damping force of the damping elements is controlled according to the earthquake-mode controller A2. Thus, in a normal state, excellent ride quality can be obtained, and in an earthquake, the vibration of a vehicle body 10 (in particular, right-to-left vibration, vertical vibration and/or rolling vibration around 1 [Hz]) of the vehicle body can be reduced, and the possibility leading to derailment or the like of the vehicle can be reduced.

摘要： PROBLEM TO BE SOLVED: To set a damping force on extension side/retraction side to soft/soft in a fail state in a damping force variable hydraulic damper capable of adjusting the damping force on the extension side/retraction side to hard/soft, soft/soft, or soft/hard.
SOLUTION: Spring forces of bias springs 38 and 41 and a shape memory alloy spring 43 are applied to a spool 27 for adjusting damping force, and the damping force is adjusted by moving the spool 27 against these spring forces by a proportional solenoid 35. The shape memory alloy spring 43 is electrically connected in series to the coil 44 of the proportional solenoid 35. The shape memory alloy spring 43 is heated by the energization of the coil 44 in a normally operating state to extend so as to act as the return spring of the spool 27. In the fail state, the energization of the coil 44 is stopped to lower the temperature of the shape memory alloy spring 43, and the shape memory alloy spring tends to be easily deformed. Accordingly, the shape memory alloy spring is compressed by the bias springs 38 and 41 to move the spool 27 so as to set a damping force to a proper damping force.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle body damping device capable of enhancing riding comfort by reducing the vibration of a vehicle body generated at the time of making the curve.
SOLUTION: When the vehicle T runs into a curve section, a vehicle body inclination control device 5 instructs starting of vehicle body inclination action to a control valve 4e and instructs starting of control action to a control part 13c. As a result, the control part 13c makes a drive current flowing a throttle control valve 13b such that attenuation of an air spring 13a becomes larger than usual time and attenuation of the air spring 13a is controlled. When the vehicle T retreats from the curve section, the vehicle body inclination control device 5 instructs completion of the vehicle body inclination action to the control valve 4e and instructs the completion of the control action to the control part 13c. As a result, the control part 13c makes the drive current flowing to the control valve 13b such that attenuation of the air spring 13a becomes the usual state and attenuation of the air spring 13a is controlled. Therefore, rolling vibration of the vehicle T generated at the vehicle body inclination action can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a method or the like for reducing a variation in pantograph contact force that can easily constitute a measuring system and reduce the variation in the contact force more easily.
SOLUTION: The displacement of a support spring 11 is measured by a sensor, and an actuator is controlled so that a low-frequency component (1 to 3Hz or lower, for example) of the variation of the displacement of the support spring 11 detected by the sensor approximates zero. That is, the low-frequency component of the displacement of the support spring 11 is set as a control target amount F
T , and the low-frequency component is controlled so as to approximate zero. Since the sensor is for measuring the displacement of the support spring 11 that is the control target amount F
T , the measurement can be performed by less number of sensors, and the measurement itself is easy. Furthermore, there are considered advantages such that the phase difference of the displacement between a shoe 3 and a support mechanism 10 is small, and that the inertia force of the shoe 3 can be neglected by paying attention to the variation of the low-frequency component, and also a control algorithm can be simplified.

摘要翻译：要解决的问题：提供一种减少易于构成测量系统并且更容易地减小接触变化的受电弓接触力变化的方法等。解决方案：通过传感器测量支撑弹簧11的位移，并且致动器被控制为使得支撑弹簧的位移变化的低频分量（例如，1至3Hz或更低）传感器检测到的11接近零。也就是说，支撑弹簧11的位移的低频分量被设定为控制目标量F T ，低频分量被控制为接近零。由于传感器用于测量作为控制目标量F T 的支撑弹簧11的位移，所以可以通过较少数量的传感器执行测量，并且测量本身容易。此外，考虑到鞋3和支撑机构10之间的位移的相位差小的优点，并且通过注意低频分量的变化可以忽略鞋3的惯性力，并且还可以简化控制算法。版权所有（C）2006，JPO＆NCIPI
