摘要
分析了缢蛏采收机主要的激振源,运用有限元软件ANSYS-Workbench对福建农林大学研制的某型缢蛏采收机前底盘建立了有限元模型,对前底盘进行了模态分析,研究了发动机激励对前底盘动态特性的影响;在确保前底盘安全性的基础上,进行减振优化,改善了前底盘结构动态特性,使前底盘具有更好的动态特性.
The main excitation source of the sinonovacula constriction harvester is analyzed. Ansys-Workbench was used to create parameterized finite element model of innovative contract harvester frame, and influence of en- gine excitation on the dynamic characteristics of the inventive front contract harvester frame is studied. Based on the analysis of the safety of the front frame, the vibration reduction optimization is carried out to improve the dy- namic characteristics of the visible frame structure, so that the front frame has better dynamie characteristics.
