The generation of motion-in-duced vortex vibration is considered to be caused by the unification of separated vorti-ces from the leading edge and secondary vortices at the trailing edge. Spring-supported tests and smoke flow visualization tests for B/D=0.62, 0.75, 1.0, 1.18 and 1.50 were conducted in a wind tunnel at Kyushu Institute of Technology. As a result, it was con-sidered that the secondary vortices at the trailing edge are not always essential for the generation of the motion-induced vortex vibration in heaving motion of each cross sec-tion. In this study, smoke flow visualizations were performed for side ratios of B/D=2.0, 4.0, 6.0 in order to elucidate the role of secondary vortices at the trailing edge in motion-induced vortex vibration in heaving motion. Spring-supported tests were also carried out in order to obtain the response characteristics of the models., XV Conference of the Italian Association for Wind Engineering(IN-VENTO 2018), 9-12 September 2018, Napoli, Italy}, pages = {496--506}, publisher = {Springer, Cham}, title = {Experimental Study on the Effect of Secondary Vortices at the Trailing Edge on Motion-Induced Vortex Vibration}, volume = {27}, year = {2019}, yomi = {マツダ, カズトシ} }
