摘要

摘要: 建立了带挤压油膜阻尼器的盘式拉杆转子动力学模型,利用非线性微分方程多周期解求解方法,对不同系统参数组合下的动力学方程进行求解,研究了带挤压油膜阻尼器的盘式拉杆转子双稳态振动特性的影响规律,比较了带与不带挤压油膜阻尼器系统稳定周期解的动力学特性.通过频谱分析得出:忽略挤压油膜阻尼器时双稳态区主要为基频振动,考虑挤压油膜阻尼器的盘式拉杆转子在双稳态区除了基频振动外,还有倍频的出现.

Abstract: The disk-rod-fastening rotor dynamics model with squeeze film dumper(SFD) was built,and nonlinear differential equation method with multiple periodic solution was used to solve those equations with different combinations of system parameters;the influence law of bistable vibration characteristics of disk-rod-fastening rotor with SFD was studied,and the models' dynamic characteristics of stable system periodic solution with and without SFD were compared.The frequency spectrum analysis shows that the disk-rod-fastening rotor without SFD presents fundamental frequency vibration on bistable state,but that with SFD presents frequency multiplication besides fundamental frequency vibration.
