摘要
Abstract
In reality, all vibration absorbers have bases. When the vibration absorber is fixed to a flexible base, the base will affect its vibration attenuation effect. Aiming at this problem, simulation researches are carried out with the power flow method in this paper. A mathematical model of the system composed of the vibration absorber with a base and coupled with an ends-fixed beam is established. With this model, the vibration attenuation effects of the vibration absorbers fixed at different positions of the beam are simulated, and the influence of the base size on the vibration attenuation effect is analyzed. On the basis, the vibration attenuation effect with double vibration absorbers attached is compared with that with a single vibration absorber attached. The results show that the vibration attenuation effect of the vibration absorber can be improved effectively by optimizing its base and installation condition. This work provides guidance for the engineering application of the vibration absorbers.关键词
