| Abstract: | Metal rubber is widely used to solve vibration problems.However,the research on the non-forming direction of metal rubber is few.Metal rubber with densities of 2.5 g/cm^3,3.0 g/cm^3,3.5 g/cm^3 and 4.0 g/cm^3 were prepared.Sinusoidal loading tests of 1-4 Hz were carried out,and the force-displacement curves were obtained.The dynamic compression mechanism of the two directions was analyzed.The effect of loading frequency and density on damping characteristics was analyzed using equivalent loss factor.The damping model of non-forming direction was established by a parameter separation method and the parameters were identified.The results show that metal rubber has anisotropy,with the increase of the density of metal rubber,the loss factor decreases.Compared with the forming direction,the non-forming direction has greater dynamic stiffness.Its damping performance is less affected by the change of frequency and more affected by the density in the low frequency band. |
