Research of a Dynamic Vibration Absorber With Tunable Resonant Frequency and Its Vibration Attenuation Characteristics
In order to improve working frequency band and damping effect of a dynamic vibration absorber,a new kind of dynamic vibration absorber was presented.Its resonant frequency could be real-time adjusted by adapting its spring stiffness.Its vibration attenuation characteristics were analyzed theoretically and numerically.According to a simulation analysis,effects of geometrical parameters were researched and optimum geometric parameters were determined.Its damping effect was simulated in a flat structure,the results shows that the dynamic vibration absorber’s working frequency band and damping effect were both remarkable.
