Numerical and experimental methods in free and forced vibrations of the rotating structure consisting of the rigid hub and three flexible beams are considered. Firstly, the system of four mutually coupled dimensionless differential governing equations is presented and then forced response of the system as well as synchronization phenomenon are investigated. Next, the finite elements method is used to design the rotating structure and analyse complex dynamic response. During the numerical calculations symmetric, as well as de-tuned rotor are analyzed. Finally, results obtained from ordinary differential equations and numerical simulations are compared with experimental tests.

三叶转子的振动、同步和定位：理论和实验研究

考虑了由刚性轮毂和三个柔性梁组成的旋转结构的自由和受迫振动的数值和实验方法。首先给出了四个相互耦合的无量纲微分控制方程组，然后研究了系统的受迫响应和同步现象。接下来，利用有限元方法设计旋转结构并分析复杂的动力响应。在数值计算过程中，对对称和失谐转子进行了分析。最后，将常微分方程和数值模拟的结果与实验测试进行了比较。
