Abstract

The synchronization characteristics of two exciters driven by induction motors independently on a typical double-layer vibration isolation system, that is, the floating raft system are studied in the paper to enhance its vibration attenuation effect. Firstly, a new dynamical model for a floating raft system driven by two exciters is established by the Lagrange equation under considering the coupling effect among floating raft system and exciters. Then, the vibration responses in all directions are obtained by the Laplace transform. Secondly, the synchronization and stability solution are obtained by using the average small parameter method. Thirdly, the results of the theoretical analysis are verified by simulations. Finally, the parameter scope of a floating raft system to enhance its vibration attenuation effect is given. Moreover, compared with the traditional model, the proposed model considering the coupling effect among floating raft system and exciters is more feasible. Additionally, the effects of the mass ratio of the eccentric block, the symmetrical installation distance, parameter differences of two motors, and other dynamic parameters such as system mass and stiffness on their synchronization and the system vibration are discussed. This paper can provide a theoretical reference for the design, modeling, and application of such double-layer vibration isolation systems including the floating raft systems to enhance its vibration attenuation effect.

浮筏系统上两台感应电机的同步特性

本文研究了典型的双层隔振系统（即浮筏系统）上由感应电机独立驱动的两个激振器的同步特性，以增强其减振效果。首先，考虑到浮筏系统与激振器之间的耦合效应，通过拉格朗日方程建立了由两个激振器驱动的浮筏系统的新动力学模型。然后，通过拉普拉斯变换得到各个方向的振动响应。其次，利用平均小参数法获得同步和稳定解。第三，通过模拟验证理论分析的结果。最后，给出了浮筏系统的参数范围，以增强其减振效果。此外，与传统模型相比，考虑到浮筏系统与激振器之间耦合效应的拟议模型更加可行。此外，还讨论了偏心块的质量比、对称安装距离、两台电机的参数差异以及系统质量和刚度等其他动态参数对其同步性和系统振动的影响。本文可为此类双层隔振系统（包括浮筏系统）的设计、建模和应用提供理论参考，以增强其减振效果。
