摘要

设计了一种将折反式鼠笼与压电陶瓷结合应用的可控弹支干摩擦阻尼器，并进行了减振试验研究。首先介绍了弹支干摩擦阻尼器对转子系统的减振机理；在此基础上设计了一种全新的折返式可控弹支干摩擦阻尼器，该阻尼器使用压电陶瓷为作动机构，尺寸小、结构紧凑、可以方便施加控制；最后将所设计的阻尼器安装于转子试验台对其减振效果进行了试验验证，试验中首次实测了动、静摩擦片压紧力。结果表明，折返式可控弹支干摩擦阻尼器对转子系统的振动具有很好的抑制作用，转子经过临界转速时的振动峰值减小70%以上，实测最佳压紧力为35N~50N。

Abstract

A tunable elastic support and dry friction damper, combining the C-shape elastic support and piezoelectric ceramic control, was designed and its vibration reduction tests were carried out.The basic mechanism of the damper was introduced.Then a brand new type damper with simpler and compact structure and convenient control performance was presented.Its effectiveness on reducing rotor vibrations was experimentally verified, and the pressing force between moving and stationary disks was tested experimentally.The experimental results show that the tunable C-shape elastic support and dry friction damper can significantly reduce the vibration of a rotor system.The maximum reduction of vibration amplitude is more than 70% at the critical speed.The optimum pressing force is 35—50 N.
