A vibration isolation device is proposed to absorb multidimensional vibration. The device is composed of double Stewart mechanisms, up-platform, and down-platform. It provides an easy way of multidimensional vibration isolation. The kinetic equation is derived from motion analysis and force analysis. Its roots show that the innate frequency of the device is lower than 5Hz and the vibration of the device attenuates rapidly. ADAMS simulation and experiment prove that the device absorbs multidimensional vibration very well. So it can be used in vibration isolation when its stiffness coefficient, damping coefficient and the sizes are designed according to the formulae derived.
