| Abstract: | 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. |
