摘要
结合动力减振器与干摩擦减振器的工作原理,以研究减振为主要目的,设计了一种新型的阻尼环。以某航空发动机转子实验台为研究对象,基于集中参数法建立了带阻尼环的转子-齿轮传动系统的弯扭耦合动力学模型。采用Runge-Kutta法数值求解系统的振动方程,并分析其在工作频率范围内的动力学响应。在此基础上,进一步分析阻尼环的安装刚度、安装阻尼、摩擦力等参数对系统振动响应的影响规律。计算结果表明:与传统阻尼环相比,新型阻尼环对转子-齿轮传动系统在高频范围内的弯扭耦合振动影响较明显;在一定的范围内增大阻尼环的结构参数,将对系统在高频范围内起到明显的减振效果,包括:转子的弯曲振动和齿轮的扭转振动;阻尼环的结构优化设计对转子-齿轮传动系统的减振效果起到重要的作用。
By virtue of the principle of dynamic absorbers and traditional damping rings, a new type of damping ring was proposed to suppress the vibration of a rotor-gear transmission system. Based on an experimental device for an aero-engine, the bending-torsion coupling dynamic model of the rotor-gear transmission system was established by using the lumped parameter method （LPM）. The Runge-Kutta method was employed to work out the simulation results, and the dynamic response of the system was also analyzed in the working frequency range. On this basis, the influences of the damping ring’s installation stiffness, installation damping and friction on the dynamic response of the system were then investigated respectively. The simulation results reveal that the new type damping ring has a significant effect on the bending-torsion coupling vibration of the rotor-gear transmission system in the high frequency range, compared to the traditional damping rings. In a certain range, it is helpful to suppress the bending vibration of the rotors and the torsional vibration of the gears in the high frequency range by increasing the structural parameters of the damping ring. The optimal design of the new type damping ring is important for the vibration suppression of the rotor-gear transmission system.
