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.

摘要： PROBLEM TO BE SOLVED: To retain a trolley line at a prescribed height position by fitting an arm on the inner periphery side of a curved passage, which is capable of oscillating in horizontal and vertical directions relative to an arm supporting metal fitting and clamps the trolley line at its front end, and disposing a spring unit which activates pushing-up force at the arm. SOLUTION: In this arm 6, an ear 9 is fixed at its front end so as to clamp a trolley line 10, and a spring fixture 11 is fixed at its front part. A catenary line M is formed at the upper position of the trolley line 10, and the catenary line M is supported by a catenary line supporting pulley K fitted at a main pipe PI. By rotating an adjusting nut which is screwed in the lower end part of a rod 71, the pushing-up force of the arm 6 caused by a spring is adjusted, so that desired pushing-up force acts on the trolley line. The arm 6 oscillating in the horizontal direction is restored at a specific position by a restoring mechanism, and the trolley line 10 is retained at a specific position.

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 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.
