    Abstract: 本發明提供一種即使是無法直接拍攝舟體部分及彈簧部分之構造的集電弓，亦可藉由圖像處理進行集電弓之接觸力的測定之接觸力測定方法及接觸力測定裝置，為此，該接觸力測定方法係拍攝集電弓100之圖像；設想將複數個彈簧102合成而在集電弓100的寬度方向之中央假設性存在合成彈簧1，並基於圖像而計算集電弓100的寬度方向之中央的相當於舟體101之位置與舟體支架104部分之相對變位，且藉由求出該相對變位與假設性合成彈簧1的自然長度之差而計算出假設性合成彈簧1之伸縮量，並對該伸縮量乘以假設性合成彈簧1之彈簧係數而求出彈簧反作用力；基於與前述圖像時間同步之實際的車輛之行走速度資料，求出作用於舟體之升力；將彈簧反作用力、慣性力及升力相加而求出接觸力。

    Abstract: 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.

    Abstract: There is provided a measuring device (dial gauge) capable of performing measurement with a desired measuring force regardless of the posture of the measuring device.
    A dial gauge in an exemplary embodiment of the present invention includes a measuring force adjustment unit provided to a body case and capable of moving and being positioned and fixed in a direction substantially parallel to a moving direction of a spindle.
    A biasing means has one end directly or indirectly engaged with the spindle and the other end directly or indirectly engaged with the measuring force adjustment unit, and biases the spindle toward a tip end.
    The measuring force adjustment unit includes an external thread portion and a connection supporting member having one end screwed with the external thread portion and the other end coupled to the biasing means. The connection supporting member is screw-fed by rotationally operating the external thread portion in such a manner that a position of the connection supporting member is changed and fixed.

    Abstract: A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.
