Fish Washbasin:Experiment of Hand-Basin-Water System and Analysis of Its Dynamic Characteristics
摘要
Abstract
A detailed kinetic-theory analysis and an experimental study of Fish Washbasin’s water spray phenomenon were carried out. First of all, modals of the Fish Washbasin in full and empty states respectively with the two ears suspended were analyzed experimentally, and the first eleven natural frequencies, modes and damping ratios were obtained. Then, the hand-rub spraying experiment was done. Using the modal analysis theory and the corresponding algorithm, the modal parameters in the spraying state were obtained. In comparison of the results with those from the experimental modal analysis, it was concluded that the dynamic characteristics and the modal parameters of the Fish Washbasin were consistent. Finally, a vibrator resonance experiment was done. With the use of an exciter, continuous excitation with different frequencies was exerted to the basin-water system of the Fish Washbasin, and the resonant spraying phenomena were observed. It means that the Fish Washbasin can spray under the resonant excitation, and the dynamic parameters agree with the modal parameters.关键词
