多层波纹钢板转子阻尼器是利用干摩擦作用实现阻尼减振的转子支撑阻尼器,钢板厚度是影响阻尼器特性的主要因素.在Hertz接触分析模型基础上,对多层波纹钢板转子阻尼器的刚度特性进行了研究.给出波纹钢板阻尼器刚度的计算方法和计算实例,并通过静态实验对理论研究进行验证.研究结果表明,波纹钢板阻尼器的刚度在不同圆周方向上变化较小,钢板厚度对阻尼器刚度影响成非线性关系.图12,参8.
Multi-layer corrugated steel rotor damper is a kind of rotor support damper that damp damping by dry friction, and the thickness of steel plate is the main factor that affects the damper characteristics.Based on the Hertz contact analysis model, the multi-layer corrugated steel rotor damper The stiffness characteristics of the corrugated steel damper are given.The calculation method and calculation example of the stiffness of the corrugated steel damper are given and the theoretical research is verified by static experiments.The results show that the stiffness of the corrugated steel damper changes less in different circumferential directions, Thickness has a nonlinear relationship with damper stiffness.
