Abstract :A mathematical model for dynamic analysis of vibration isolation systems is presented. The model is based on small deformation mechanics of 3-D rigid body with 6-DOF and supported by flexible structural members. The mass, static stiffness and damping matrices for the system are derived. Eigen-analysis using the presented model and solution method are applied to a real spacecraft vibration test system with base isolation. A finite element model of the system is also developed. The results of the proposed math model, FE model and test results of a real vibration testing system are compared. The math model solution results agree well with the FEM model and actual test results. The model can be used in the design of the engineering structures with base isolation such as vibration and acoustic test systems, large static and dynamic testing systems, buildings etc.
Keywords : Vibration isolation, rigid body motion, eigen analysis
