摘要： PROBLEM TO BE SOLVED: To provide a damper for suppressing relative vibration between two suspension wires with frictional resistance between members. SOLUTION: In the damper 1, two suspension wires M suspended so as to support different trolley wires downward and extend substantially in parallel are interconnected, and the relative vibration between the two suspension wires M is suppressed by the frictional resistance between the members. A body 2 to be fixed to one suspension wire M and a turning arm 8 pivoted by the other suspension wire M so as to move relatively in the axial direction is pivotably adhered to the body. The turning of the turning arm 3 by the relative vibration between the two suspension wires M is suppressed by the frictional resistance by a frictional resistance member 4. The frictional resistance by a frictional resistance member 4 can be adjusted by position change of a spring bearing member 11. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively transmit the wave motion of a trolley wire at the part where a hanger is mounted and to damp the wave motion with a lightweight and inexpensive structure. SOLUTION: A hanger 3 has a hanger 4 and a grip member 5. A rubber elastic body 7 is vulcanized and integrally fixed to the curved part 6 of the hanger 4. The base of the rubber elastic body 7 wraps the curved part 6 uniformly. A protruding part 9 protrudes toward a hanging wire 2 with a horizontal cross-sectional area thereof gradually from the base 8 and contacts the outer periphery of the cylindrical part 10a of a protection cover 10 fixed to the hanging wire 2 at the protruding end. The wave motion of a trolley wire 1 produced when the pantograph of a train passes transmits a hanging part without producing a large reflection wave by means of the rubber elastic body 7 having a relatively large transmitting coefficient of wave motion. At the same time, vibration energy transmitted to the hanger is damped by the rubber elastic body 7 to prevent the vibration of the trolley wire 1. Accordingly the separating ratio of the trolley wire 1 from the pantograph is reduced to collect electricity stably and the stress to the hanger 3 is reduced to make the life of the hanger 3 longer.

摘要： PROBLEM TO BE SOLVED: To provide a vibration control tool which can be simply and surely mounted on a trolley wire hanger in use and transmit and damp the wave motion of a trolley wire effectively. SOLUTION: A trolley wire is suspended by a hanging wire via a hanger. A vibration control tool mounted on the curved part of the hanger has a mounting member and an elastic body 9. The mounting member is fixed such that it surrounds the curved part in a predetermined range. The mounting part comprises a base body 11 mounted on the inner side of the curved part 6 and a cover 12 positioned outside the curved part 6 and fitted in the base body 11. The elastic body 9 made of rubber has an arc-shaped support part 9a curved along the curved part and a protruding part 9b protruding downward inside the curved part from the top of the support part 9a and reducing a horizontal cross-sectional area gradually. The wave motion of the trolley wire caused by a sliding pantograph travels on the trolley wire without being reflected by means of elasticity of the elastic body 9 of the vibration control tool and is damped because vibration energy is absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a wave separating method for separating a wave into a progressive wave and a regressive wave which is significant as an analyzing method for capturing the wave complicatedly propagating through a trolley line or the like in detail. SOLUTION: A wave separating method (a time difference method) is a method for separating a wave (y) (x, t) propagating in the longitudinal direction (x-direction) of a long body accompanied with displacement in a vertical direction to the (x) direction into a progressive wave and a regressive wave. At first, acceleration is measured at two points x1 and x2 with an interval Δx sufficiently shorter than the wavelength of the wave. Then, the wave is separated into a progressive wave f(x1 -ct) and a regressive wave g(x1 +ct) by f(x1 -ct)=1/2Δt y(x1 , t+Δt)-y(x2 , t)}dt and g(x1 +ct)=-1/2Δt y(x1 , t-Δt)-y(x2 , t)}dt when (c): a wave propagating speed and Δt=Δx/c.

摘要： PROBLEM TO BE SOLVED: To accurately and continuously measure the ruggedness of a long length body without being affected by the vertical vibration of a measurement base. SOLUTION: A non-contact displacement sensor 1a detects trolley line displacement at a measurement spot (x) and outputs a first displacement signal and a second non-contact displacement sensor 1b detects the trolley line displacement at the measurement spot (x+Δx) and outputs a second displacement signal. The displacement signals are respectively passed through amplifiers 2a and 2b, A/D converters 3a and 3b and low-pass filters 4a and 4b and inputted to an inclination computing element 5. The inclination computing element 5 obtains a displacement difference Δy from the second displacement signal and the first displacement sensor and calculates an inclination signal Δy/Δx from that and a sensor head attachment interval Δx further. An integrator 6 executes correction by the ruggedness wavelength λ of the long length body to the inclination signal Δy/Δx, performs integration and outputs the ruggedness signal of the long length body to an output device 8.

摘要： PROBLEM TO BE SOLVED: To enhance accuracy in measurement of a tension by calculating wave propagation speeds of vibrations of a specific frequency measured at measurement points set on an electric wire via a constant distance, and calculating the tension of the electric wire from an average speed. SOLUTION: An accelerometer 2 is set at two points of a train line 1 separated by a constant distance L. A vibration-measuring means is constituted of the accelerometer 2 and a strain amplifier 3. A vibration acceleration of residual vibrations generated at the train line 1 when the train passes is measured. The vibrations may be generated by applying a shock artificially. A measuring apparatus 20 is provided with an A/D converter and a memory 4 as a data- recording means, a microcomputer 5 as an operating means, a controller and a display device 6 in addition to the strain amplifier 3. The data-recording means A/D converts measured vibration waveforms of approximately 5 seconds and records in the memory. The data are processed by the operating means, whereby a wave propagation speed is calculated with the use of 100Hz or lower frequency. A tension is calculated with the use of an average value of the wave propagation speed.
