摘要： PROBLEM TO BE SOLVED: To provide a method for detecting an abnormality in a pantograph by focusing attention on vibration characteristics of a pantograph without depending on visual observation.SOLUTION: Mechanical impedance (reference impedance) of a pantograph is measured in an excitation test when a pantograph to be an object is in a normal state. Contact force between the pantograph and a trolley wire and an acceleration of the trolley wire closest to a contact point between the pantograph and the trolley wire are measured in a place where an electric train performs an operation to lift the pantograph (called as an inspection place). Mechanical impedance (inspection impedance) of the pantograph in a frequency where the pantograph and an electric train line are integrally perform a free vibration after the pantograph is lifted at the inspection place is obtained by using contact force and an acceleration. The reference impedance is compared with the inspection impedance to thereby determine whether an abnormality exists in the pantograph or not.

摘要： PROBLEM TO BE SOLVED: To provide a collector head improved to safely travel even after a slider body is slipped off from a pantograph.SOLUTION: The collector head 20 includes: a bottom plate 21; front-rear long side plates 22; right-left short side plates 23; and right-left auxiliary sliders 24. A recess S (a fitting part) long in the lateral direction surrounded by the inner end faces 24a of the right-left auxiliary sliders 24 and the upper end faces of the front-rear long side plates 22 is formed to the top face of the collector head 20. The slider body 10 is held in the recess S. The inner end faces 24a of the right-left auxiliary sliders 24 are formed in a tapered shape upwards directed to the outside. Consequently, a trolley wire is guided in the external direction of the fitting part along the tapered ends 24a of the fitting part S when the slider body 10 is slipped off from the collector head 20 and the trolley wire must be slid in the fitting part S of the collector head 20.

摘要： PROBLEM TO BE SOLVED: To provide a method to detect malfunctions of a pantograph (malfunctions of dynamic characteristics) by monitoring a behavior of a trolley wire influenced by the malfunction of the dynamic characteristic of the pantograph.SOLUTION: An accelerometer 30 is installed in a monitoring position P1 of the trolley wire T, and the vertical acceleration of the trolley wire T is detected. The vibration of the trolley wire when the monitored pantograph 1 passes a monitoring position P1 (so called the monitoring vibration) is measured by an accelerometer 30. Meanwhile, the vibration of the trolley wire, when this pantograph is normal, and monitoring position P1 is passed (so called the reference vibration) is measured by the accelerometer 30. Then the reference vibration and the monitoring vibration are compared, and whether the dynamic characteristic of the pantograph in the operating state is normal or abnormal is detected.

摘要： PROBLEM TO BE SOLVED: To provide a method of capable of measuring mechanical impedance of a trolley wire on a running car body based on a contact force of a pantograph and vertical vibration of the car body. SOLUTION: A frequency responding function H(ω) between the pantograph contact force of a running vehicle and a car body vertical acceleration of the vehicle having the pantograph is determined by H(ω)=Wc/Wp, based on the contact force and the acceleration. In this equation, Wc is a cross spectrum between the pantograph contact force and the car body vertical acceleration, and Wp is a power spectrum of the pantograph contact force. A mechanical impedance of the trolley wire is estimated for minimizing the error between a calculation result of a frequency responding function H'(ω) of the contact force to a previously determined vertical acceleration and a calculation result of the frequency responding function H(ω) between the car body vertical acceleration using measured data of the running vehicle and the pantograph contact force.

摘要： PROBLEM TO BE SOLVED: To provide a contact force measuring method and a contact force measuring apparatus of a pantograph which can measure a front and rear direction contact force of a collector shoe of a pantograph. SOLUTION: When the front and rear direction contact force Ff is applied to the collector shoe 12 from a trolley wire 9, a torsion moment Mf is developed in the collector shoe 12, and torsion moments MA, MB are generated on sections A, B of the collector shoe 12. When rotation inertia of the collector shoe 12 in a section AB is In, the torsion moment Mf is expressed by Mf=(-MA+MB)+ In. When a distance from a figure center of the collector shoe 12 to the upper surface is v, the front and rear direction contact force Ff is expressed by Ff=(1/ v)Mf. The torsion moments MA, MB can be obtained by measuring the shearing stress with a strain gauge for two axes. The rotation inertia In can be obtained from measured results with an accelerometer and equivalent mass.

摘要： PROBLEM TO BE SOLVED: To provide a method of measuring wave motion propagation speed or tension of a trolley wire based on contact force variation of a pantograph measured on a running vehicle. SOLUTION: Regarding to the contact force variation of trolley line- pantograph system, a contact force variation frequency fv generated by the fact that exciting wave motion excited as a result of periodicity of the trolley line propagates through the trolley line, reflects at a discontinuous point of the trolley line, and comes into the pantograph again is represented by fv= (1+β)/(1-β)}×fL. By normalizing the frequency represented by the equation by a train speed, KV= (1+β)/(1-β)}×KL is derived. It is recognized that the wave number KV varies with a ratio β of the train speed and the wave motion propagation speed of the trolley wire. Therefore, when the wave number KV of a dynamic component included in the contact force variation is accurately provided, and simultaneously train speed v is also obtained, the wave motion propagation speed of the trolley wire can be obtained.
