Installing Location&Equipment Selection of Ship Positive Vibration Compensator

开展伯努利梁受迫横向振动机理研究,采用模态叠加法推导了伯努利梁受迫振动的响应表达式,分析了振动响应与激振力和激振力矩作用位置间的关系。总结了减振器安装位置的选择规律和激振力幅值的计算方法,并采用有限元法进行验证,在某小型集装箱船的减振设计过程中进行了应用。

The mechanism of forced transverse vibration of Bernoulli beam is studied.The response expression of forced vibration of Bernoulli beam is derived by mode superposition method.The relationship between vibration response and the position of excitation force and moment is analyzed.The selection rule of damper installation position and the calculation method of excitation force amplitude are summarized.The finite element method is used to verify and reduce the vibration of a small container ship It is applied in the process of vibration design,and it is applied in the vibration reduction design process of a small container ship.
