针对工程中隔振器的选择问题,在满足隔振系统总刚度和总阻尼不变的条件下,运用有限元方法分析了隔振器三种选择方案中结构的动力响应.结果表明:隔振器选择不同会在很大程度上影响初设隔振系统的性能.当选择隔振器刚度大、个数少,隔振器与结构接触面少时,隔振系统能够起到更好的隔振作用.
Aiming at the selection of vibration isolator in engineering, the dynamic response of the structure in the three options of vibration isolator is analyzed by the finite element method under the condition of satisfying the total stiffness and total damping of the vibration isolation system. The results show that vibration isolation Vibration isolation system can play a better role in vibration isolation system when the vibration isolator’s rigidity is large and its number is small and the interface between vibration isolator and structure is little. effect.
