摘要： PROBLEM TO BE SOLVED: To provide a contact force measurement method and a contact force measurement device in which the contact force of a pantograph can be measured by image processing, even for the pantograph having a structure of which collector head and spring portions cannot be directly photographed.SOLUTION: A pantograph 100 is imaged, and a plurality of springs 102 in the image are synthesized to assume that there is a synthesized spring 1 virtually in the middle of the pantograph 100 in the width direction. From the image, a relative displacement is calculated for a position corresponding to a collector head 101 in the middle of the pantograph 100 in the width direction and a collector head support 104, and difference of the relative displacement and the natural lengths for the virtual synthesized spring 1 is obtained, thereby calculating an expansion amount of the virtual synthesized spring 1. Thereafter, a spring reaction force is obtained by multiplying the expansion amount by a spring constant of the virtual synthesized spring 1, a lift force acting on the collector body is obtained by the real vehicle running speed data which is time-synchronized with the image, and a contact force is obtained by adding the spring reaction force, an inertia force and the lift force.
