CABLE EXCITATION DEVICE USING AC SERVO MOTOR FOR EVALUATING DYNAMIC CHARACTERISTICS OF CABLE STRUCTURE

摘要

PURPOSE: A cable excitation device for evaluating dynamic characteristics of a cable structure is provided to facilitate excitation control by including an AC servo motor. CONSTITUTION: A cable excitation device for evaluating dynamic characteristics of a cable structure includes a supporting member(500), a gear box(100), a first rotation frame(110) and a second rotation frame(120), and an AC servo motor(200). The supporting member(500) is fixed to the upper end part of the cable(2000). The gear box is arranged in parallel to the axis direction of the cable(2000). The first rotation frame(110) and the second rotation frame(120) are included at both sides of the gear box(100). The AC servo motor(200) adjusts rotation thereof by being electrically connected to a servo driver(210).
