摘要：针对多振源,提出利用多振源之间的互相作用来达到抑制振源强度的方法,以船舶甲板为研究对象,将其简化为矩形简支薄板模型,分析其在受到两个振源激励作用时的振动状况,将薄板总动能作为衡量振动强度的指标,理论分析和实验结果表明,当2振源之间的相对位置以及相位差在一定范围内时,薄板的总动能比单一振源激励时的薄板总动能小,薄板的振动得到了有效抑制。
At the present,many studies are focus on suppressing the vibration strength of single vibration source.For multiple vibration sources,a new vibration suppression method was provided by interaction of vibration sources.The ship’s deck was taken as the research object,which was reasonably simplified into a rectangular simply supported thin plate model.The vibration state of the plate model under the excitation of two vibration sources was analyzed.The theoretical analysis and experiment verification showed that the total kinetic energy in the case of two vibration sources acting on the plate will be smaller than that in the case of single vibration source if the relative locations and phase difference of two vibration sources were in reasonable range,thus the vibration of the plate can be suppressed.
