| Abstract: | Studies are conducted in this paper to analyse and compare the random vibration dynamic absorber whose main vibration system is stimulated respectively by extraneous force or foundation. According to the optimal object of the minimum of the main quality displacement variance, it is derived that two kinds of computation formula of the optimal parameter based on the random vibration dynamic absorber. The calculating results show that these formula are effective, and the effect of reducing vibration is satisfactory. This paper will be of theoretical value in the designing and using of dynamic vibration absorber. |
