提出了一种改进的Oden摩擦模型,用于模化非线性干摩擦阻尼,并给出了叶片系统的运动微分方程.用该模型计算了一个5片成组叶片系统的振动响应,研究了阻尼联接件在叶片的不同高度位置上以及不同的激振力和正压力数值对阻尼叶片振动特性的影响,得出了一些有参考价值的结论.
An improved Oden friction model is proposed to model the nonlinear dry friction damping. The differential equations of motion of the blade system are given. The model is used to calculate the vibration response of a group of five blade systems. The influence of the damping couplings on the blade height and the different exciting and positive pressure values on the vibration characteristics of the damping blades are studied. Reference value conclusion.
