Characteristics Analysis for Floating Raft Isolation System Based on FEM and PPIGA

Based on the object of marine air-compressor and ANSYS soft, a finite element model of vibration system is designed to analyze vibration-reduce effect through adjusting different parameter characteristics. In a way, the result is valuable for reference for more detailed research. Then using pseudo—parallel improved genetic algorithm (PPIGA) to optimize quality and stiffness of the floating raft isolation system. The results show that PPIGA has good effect in parameter optimization of the floating raft isolation system.
