OIL DAMPER WITH DISPLACEMENT AND VELOCITY SENSOR FOR MEASURING AND CONTROLING OSCILLATION OF STRUCTURE

摘要

PURPOSE: A displacement and speed sensor mounting oil damper for measuring and controlling structural vibration is provided to reduce vibration by detecting the movement and speed displacement of vibration which influences to bridges, buildings, and structures. CONSTITUTION: A displacement and speed sensor mounting oil damper for measuring and controlling structural vibration comprises a cylinder(100), a sensor displacement detector(200), a sensor circuit(300), a core type displacement sensor(400), and an interface terminal(500). The cylinder reciprocates in order to induce internal oil(10) to flow. The sensor displacement detector detects the movement displacement generated by the reciprocation on a real time basis. The sensor circuit converts the movement displacement detected through the sensor displacement detector into speed displacement. The core type displacement sensor senses and transmits the movement and speed displacement to the interface terminal. The interface terminal transmits the movement and speed displacement to an external device through the core type displacement sensor.
