摘要
阐述了在隧道射流风机安装施工中,用变刚度变阻尼减震器替代传统的橡胶减震块,大幅度降低射流风机在运行时的振动,提高风机运行的安全性;同时对变刚度变阻尼减震器的安装调试方法进行了介绍。
The using of variable damping and stiffness absorber in tunnel jet fan installation instead of tradi- tional rubber absorber is simply introduced, which can greatly reduce the vibration of jet fan in operation and improve the safety of the fun, and meanwhile, the installation and debugging methods for variable damping and stiff ness absorber are introduced.
