Transmissibility is the main performance evaluation index of Metal Rubber (MR) isolator, which can be got by sine sweep frequency test. At different temperature, the sine sweep frequency test is done with different structural parameter MR isolator. The influence that relative density and pre-deformation have on transmissibility and natural frequency when temperature changed is analyzed. The changing regularity of MR isolator’s transmissibility at different temperature is explored. Research results provide the basis for designing MR isolator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
