This study analyzes the modeling and dynamics of a novel passive multi-degree-of-freedom\n(MDOF) vibration isolation platform which can achieve a significant isolation effect. Symmetrical\nscissor-like structures (SLSs) are utilized in the proposed MDOF isolation platform as the supporting\nand isolation elastic components. Based on the mathematical modeling and theoretical analysis of the\nMDOF vibration isolation system with SLSs, the effects of structural parameters and joint friction on\nthe stiffness and damping properties are investigated. It is shown that due to geometric relations\nwithin the SLSs, the natural frequencies can be reduced via adjusting structural parameters of the\nSLS for different direction vibration isolation. Theoretical and experimental results show that the\nSLS isolation platform can achieve much better loading capacity and vibration isolation performance\nsimultaneously by only using linear passive components because of the MDOF adjustable stiffness\nproperty. Therefore, with low cost and energy consumption, the proposed novel isolation platform\ncan improve the vibration suppression in various engineering practices.
