AEROELASTIC PERFOEMANCE AND FLOW-BEHAVIOR AROUND MULTI-STRAND CABLE WITH OR WITHOUT HELICAL STRAND

Abstract

The present research is a basic research for development of a cable with good aeroelastic performance. A proposed cable in the present study is a multi-strand cable from viewpoint of cost performance. Wind tunnel tests were conducted to examine the aeroelastic performance of the multi-strand cable with or without helical strand. As a result, it was made clear that multi-strand cable with helical strand had better performance for redudng amplitude of aeroelastic vibrations and that the helical strand makes the drag and the lift forces decrease.
