摘要
Abstract
Based on multi-rigid-body dynamics, structural dynamics and modal synthesis method, a new model of double-stage vibration isolation system with elastic raft plate and foundation is established. Program of computation is written for calculation of the natural frequency and shock response of the system. To prove the correctness of the model, results of the natural frequency are compared with those from FEM. Effect of elasticity of the raft plate and foundation on shock response of the double-stage vibration isolation system is analyzed with numerical simulation. As a consequence, a reasonable model of double-stage vibration isolation system can save computation time and meanwhile ensure acceptable computation accuracy. The conclusion can be referred to deal with some practical problems of the double-stage vibration isolation system.关键词
