碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 101 / The research of the resistance characteristics of trimaran has two purpose:(1)To investigate the effect of side-hull position on the resistance characteristics of trimaran and find out the optimization longitudinal position of side-hulls.(2)To study the effect of side-hull with the hull of curved surface or the plane surface inward on the influence of wave interference between main-hull and side-hulls.
Two trimaran models were used to study the optimization position of side-hulls, the influence of side-hull with the hull of curved surface and the plane surface inward on the wave interference of trimaran by ship model test. The test results show that when the Froude number is greater than 0.5, the total resistance coefficient is always lowest at the forward and outboard position of side-hulls or backward and inboard position of side-hulls. Furthermore, the resistance tests of the effect of side-hull with the hull of curved surface and the plane surface inward revealed that the resistance performance of the plane surface is better than that of curved surface. Finally, through the comparison of test results, the total resistance coefficient of the trimaran could be decreased significantly if the interference of bow waves between main-hull and side-hulls could be avoid.
