摘　　要：本文采用三维有限元法 ,对万家寨机墩组合结构进行了动力分析 ,研究了引起机组振动的振源 ,并与机墩组合结构固有频率进行了共振校核。振动响应值与频率联合进行评估 ,初步探讨了振动响应对人的振动感觉。In this paper dynamic analysis of the supporting composite structare and the vibration sources of unit evoked by vibration are studied with three\|dimensional finite element method,and the resonance is contrasted with the natural frequency of the supporting composite structure.Combination of the respondent value of vibration and the frequency is evaluated,the men's vibration sense in the vibration response is discussed.
