针对船舶航行过程中动力装置隔振系统受到振动和冲击综合作用的问题，提出了半主动吸振抗冲击集成控制系统．该控制系统采用半主动吸振器调节自身的频率以实现对振动和冲击的控制．基于动力吸振方法对复杂隔振系统抗冲击规律进行了研究，利用逐步积分法求解了系统的冲击响应，并讨论了动力吸振器的安装位置、质量、刚度以及阻尼对抗冲击效果的影响，提出了优化方法．仿真结果明：在不同设备上分别安装吸振器的抗冲击效果明显优于单独在设备或浮筏上安装吸振器；合理优化吸振器参数后可使设备A、B的时域冲击衰减率达到27．3％和36．7％．%In an effort to mitigate the problem of the power plant vibration isolation system experiencing vibration and impact during the voyage, an integrated control system of semi⁃active vibration absorption was presented. The control of vibration and impact was achieved by regulating operating frequency of the semi⁃active vibration absorber. The regular pattern of impact resistance of complex vibration isolation system was examined utilizing the dynamic vi⁃bration absorber method. The system impact response was solved using the step⁃by⁃step integration method and the influence of resistance impact was discussed when the parameters changed, such as installation position, mass, stiffness and damping of the vibration absorber. If present, then optimization methods were proposed. The simulation results indicate the effect of impact resistance is better when the vibration absorbers are installed on different de⁃vices, as opposed to the effect when only installed on the floating raft or a device. The impact attenuation rate on time domain of device A and B can reach up to 27.3% and 36.7%, respectively, when the parameters of vibration absorber are optimized legitimately.
