摘要： PROBLEM TO BE SOLVED: To provide a rolling stock structure with a floor structure capable of minimizing increase of mass of a rolling stock structure and effectively restraining oscillation radiation sounds (solid propagation sounds) defining noises in a compartment in high-speed traveling, a floor structure provided to the rolling stock structure, and its manufacturing method.
SOLUTION: A floor structure 100a with a large surface density is arranged at a portion, at which an oscillation level of an underframe 40 is large, to restrain the oscillation level, thereby reducing a sound pressure level, radiated from a surface of the floor structure 100a into a compartment. Because the floor structure 100a with a large surface density is arranged only at a portion, at which the oscillation level of the underframe 40 is large, and a floor structure 100b with a small surface density is arranged at a portion, at which the oscillation level of the underframe 40 is small, increase of a mass of the floor structure can be minimized. Therefore, a light weight of this rolling stock structure 1 can be promoted, and noises in the compartment of the structure can be restrained.

摘要： PROBLEM TO BE SOLVED: To enhance accuracy in autognosis of soundness of system composition elements in a vibration control device for railway vehicle suppressing vibrations in the horizontal direction of a vehicle body.
SOLUTION: A controller 13 suppresses the horizontal vibrations of the vehicle body 2 by controlling an actuator 6 based on detection by an acceleration sensor 12. The controller 13, in the autognosis mode, stops the actuator to one of trucks 4 in front/rear parts of the body 2, and operates the actuator 6 to a certain direction to the other truck 4 to excite the body 2. Relative displacement between the body 2 and the trucks 4 is detected by a stroke sensor 11 to diagnose the soundness of thrust polarity of the actuator 6 comparing the relative displacement with a predetermined reference value. At this point, the actuator 6 is once operated to the opposite direction before exciting the body 2, which can solve hysteresis accompanying the relative displacement between the body 2 and the trucks 4 to enhance the diagnosis accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a railway vehicle structure including a floor structure having excellent manufacturing workability, and suppressing transmission noise and vibration emission noise (solid-borne sound) which determine noise in the vehicle during high-speed running without increasing the mass of the railway vehicle structure.SOLUTION: A large noise part of an underframe 40 in a truck upper part is recognized based on a test result. A damping material 110 and a floor structure 100a large in specific gravity are arranged only in the large noise part of the underframe 40. A floor structure 100b small in specific gravity is arranged in a small noise part of the underframe 40. The increase of mass can be minimized by the floor structure, thereby achieving the railway vehicle structure 1 that facilitates weight reduction and reduces noise in the vehicle. The damping material is directly stuck to the upper surface of the underframe 40 secured in flatness, thereby improving manufacturing workability.

摘要： PROBLEM TO BE SOLVED: To enhance precision and reliability in self-diagnosis of the soundness of system components in a vibration controller for rolling stock which controls vibration of the body in the right and left directions. SOLUTION: A controller 13 controls vibration of the body 2 in the right and left directions by controlling the thrust of an actuator 6 based on the detection of an acceleration sensor 12. In the self-diagnosis mode, the controller 13 stops the actuator 6 for one of trucks 4 in front and rear of the body 2, switches a variable damping force damper 7 to the low damping force side for the other truck under a state where the variable damping force damper 7 is switched to the high damping force side, and shakes the body 2 by supplying a drive signal to the actuator 6, thereby operating the actuator 6 in the fixed direction. Relative displacement of the body 2 and the truck 4 is detected by a stroke sensor 11 and compared with a predetermined reference value, thus diagnosing the soundness of thrust polarity (direction of thrust) for the drive signal of the actuator 6.
