Abstract The non-smooth nonlinear energy sink (NSNES) is used to suppress the vibration of the rotor-blade system. Firstly, the structure and working principle of the NSNES for rotor-blade system are introduced. Then, the dynamics model of the rotor-blade-NSNES system is established by Lagrangian method. And then, numerical simulations are applied to evaluate the vibration suppression ability of the NSNES on rotor and blade. The results show that the suppression rates of NSNES on the rotor and the blade can reach 81% and 74% in steady state resonance under given parameters, respectively; and for transient vibration of blade, a 1.85 times dissipating speed is obtained in rotor-blade system with NSNES than that without NSNES. In particular, NSNES has better vibration suppression capability than linear dynamic vibration absorber (LDVA) when both have the same vibration absorption mass.

非光滑NES在转子-叶片系统振动抑制中的应用

摘要 非光滑非线性能量汇(NSNES)用于抑制转子-叶片系统的振动。首先介绍了旋翼叶片系统NSNES的结构和工作原理。然后，利用拉格朗日方法建立了转子-叶片-NSNES系统的动力学模型。然后，应用数值模拟来评估NSNES对转子和叶片的振动抑制能力。结果表明，在给定参数下，NSNES对转子和叶片的稳态共振抑制率分别达到81%和74%；对于叶片的瞬态振动，有NSNES的转子-叶片系统比没有NSNES的转子-叶片系统获得了1.85倍的耗散速度。特别是，
