APPARATUS FOR CABLE EXCITER CABLE WITH SINGLE WEIGHT

摘要

PURPOSE: A cable exciter system excited with a single weight is provided to execute the minute excitation by minimizing the component force and relatively simplifying the structure. CONSTITUTION: A cable exciter system(10) excited with a single weight is composed of a housing(20), a fixing unit(30), a guide frame(41), an exciter member(43), and an exciter device(40). The housing is installed in a cable of a cable-stayed bridge or an extradosed bridge. The fixing unit is installed inside the housing to fix the housing to the cable. The guide frame is extended from the one side of the housing. The exciter member is slidably installed along a guide rail(42) installed in the guide frame. The exciter device has a driving unit(50). The driving unit makes the exciter member reciprocate along the guide rail.
