浮筏隔振系统仿真结果的中间频段数据处理方法
Middle Frequency Band Processing Method in the Simulation of Floating Raft Isolation System
【摘要】 为了解决浮筏隔振系统仿真结果的中间频段数据处理问题,基于浮筏隔振系统低频段的有限元分析结果和高频段的统计能量分析结果与试验结果的对比分析,提出采用模糊理论进行数据回归处理来得到中间频段的仿真结果,从而提出一种估算浮筏隔振效果的方法。
【Abstract】 The data regression processing method based on fuzzy mathematics theory is proposed to get the middle frequency band simulating result based on Finite element result of low frequency band and Statistics Energy Analysis result of high frequency band to get a complete frequency band result and solve the middle frequency band result processing problem in the simulation of floating raft isolation system.
