摘　　要：针对旋转机械在不平衡工况下的周期振动载荷问题,按照隔振器设计原则,设计适用于旋转机周期振动的金属橡胶隔振器模型,以ZDT-2Y/2W-3旋转振动试验台实际参数为参照,制备金属橡胶试块。最后基于ANSYS发展了在旋转机械振动条件下对于金属橡胶材料采用正交各向异性阻尼参数识别的有限元分析方法,同时依照材料强度的第四强度理论对其评定。结果证明该有限元仿真方法可用于旋转机械不平衡状态下的金属橡胶隔振分析。Aiming at the problem of periodic vibration loads of rotating machinery under unbalanced conditions,the metal rubber isolator model is designed for periodic vibration reduction of rotary machines.The metal rubber block is prepared referring to the actual parameters of ZDT-2Y/2W-3 rotary vibration test-bench.Then,a finite element analysis method based on ANSYS is developed for the identification of the orthotropic damping parameters of the metal rubber material under the vibration condition of the rotating machinery.Results of the simulation are evaluated according to the fourth strength theory of materials.The results show that the finite element simulation method can be applied to the vibration isolation analysis of metal rubbers under the unbalanced state of rotating machinery.
