船舶用无阻尼动力吸振器参数影响的分析

摘要

本文建立了以梁的最大动能为减振目标函数的理论公式,以梁为研究对象,通过分析连续系统在简谐激励下无阻尼动力吸振器吸振的特点,详细阐述了无阻尼吸振嚣的位置参数和质量参数对减振目标函数的影响.还包括对目标函数中较为敏感的参数分析,该研究内容在动力吸振器参数优化及振动控制理论的研究中具有一定的应用价值.%The characteristic is analysed for the undamped vibration absorbers attached to the continuous systems under the simple harmonic excitation. The theoretical formula of objective function aim at maximal kinetic energy of beam is founded for the beams, and the influence of absorber's locations and structure parameters on the objective function is also considered. There is a certain value of the study content for the parameter optimization of dynamic vibration absorber and the theory of vibration control.
