INVESTIGATION OF SELF-EXCITED PLANING VIBRATION AT LARGE WETTED ASPECT RATIO.
Abstract
The effects of beam, sweepback, trim, load, speed, natural frequency, and vibrational direction on the incipience of vibration of planing surfaces with large wetted aspect ratio were investigated. Experimental results are presented in nondimensional form and correlated with results from a semi-empirical analysis. These results lead to the conclusion that the vibration under study was a dynamic instability involving an induced rise of the water surface ahead of the planing surface. Based on the results of the study, means of alleviating the vibration are suggested. (Author)
