摘要
应用传递矩阵法分析弹性底座、非对称多支承复杂系统的隔振效果,揭示了附加小中间质量对具有一个对称面的复杂隔振系统的影响规律,应用优化方法探讨了复杂隔振系统的逆设计问题。最后由计算机确定系统的最佳设计参数,并给出各种传递输出量的性能曲线,为解决非对称系统隔振设计问题提供了一种理论分析方法。
Invetegates influence of an additive small medium mass on isolation efficiency of complex system with asymmetric-mul-tiple-mount and nonrigid foundation.Dynamic transfer equations of the system is derived by transfer matrix method and inverse designs of the system is dicussed by optimization method. With the computer,optimal design parameters of the system was determined and property curves of some transfer outputs from a four mounts system as an example was given. Result shows that inserting a small medium mass in the system is an effective way to attenuate viberation.
