英文摘要	A possible application for multi-dimensional vibration isolation is the Stewart vibration isolation system (SVIS). An innovative parameter design method is provided in this research, in which the SVIS is equated to an elastic node with stiffness-damping characteristics of six degrees of freedom. This paper addresses parameter design as a crucial issue for the SVIS integrated in large and complex systems. Two levels make up most of the content. First, the stiffness synthesis and deconstruction processes of the SVIS are inferred and demonstrated, suggesting that the elastic node may be used to quickly and effectively identify the stiffness-dumping of the SVIS. A system of parameter design flow for the SVIS integrated into complex systems is suggested based on the theory. A Stewart platform prototype is next created. To validate the hypothesis, FEM simulations and dynamics tests are carried out sequentially. The simulation findings demonstrate that the prototype's six natural frequencies depart from the theory within 1%, and the frequency response curves closely match the theory. According to test results, the Z-directional resonant frequency falls 1.7% below predictions. The X/Y-direction frequency response curves include certain poor characteristics caused by structural clearances, but overall trends support the notion. The study offers theoretical direction for SVIS-integrated optimization design in complex systems.
