船舶辅机浮筏半主动非线性隔振系统振动特性分析
|
摘要
磁流变阻尼器因其低耗能、响应迅速等特点而被广泛应用。文章采用一种改进的Bingham模型对船舶辅机浮筏隔振装置中的非线性磁流变阻尼力进行建模。该模型简单且含滞后特性,便于理论分析。对建立的船舶辅机浮筏隔振系统的非线性动力学模型,通过平均法求解船舶辅机浮筏半主动隔振系统的理论解,并运用Matlab对理论解进行数值仿真验证。以力传递率作为评价指标,分析了磁流变阻尼器各参数对隔振效果的影响规律。研究结果可为非线性船舶辅机浮筏隔振系统的设计提供理论依据,从而能更有效地控制船舶辅机的振动。
MR(magneto-rheological) dampers in semi-active control have rapid variated damping properties with very low power requirements. A revised Bingham model is used to describe the nonlinear damping force for MR damper of auxiliary floating raft isolation system in ship. The model with hysteresis characteristics is simple in expression and convenient for theoretical analysis. Nonlinear dynamic equation of the floating raft isolation system is established based on the model. A theoretical solution of dynamical response and vibration transmissibility for the ship floating raft semi-active isolation system are obtained by average method, which is verified by numerical solution with Matlab. In addition, the effect of model parameters of MR damper on the system's vibration isolation is studied by taking transmissibility as index. The research results provide theoretical basis for designing the nonlinear vibration isolation system of auxiliary floating raft and then the vibration can be controlled more effectively.
