摘　　要：应用弹性力学有限元理论,采用有限元分析软件ANSYS对阿基米德蜗杆进行模态分析,得到了蜗杆的10个低阶固有振动频率和模态振型,并对蜗杆材料对固有振动频率和模态振型的影响进行了对比分析。所得结论反映了蜗杆的动力学特性,同时也为蜗杆传动系统的动态响应分析及结构设计提供了理论依据。Theory of elastic mechanics finite element and the ANSYS software,modal anlysis of Archimedes worm is carried out.10 low order natural frequencies and modes of vibration are obtained.A comparative analysis for the effect of archimedes worm＇s material on the natural frequency is done.The conclusions reveal the dynamic performance of worm,it also offer the theory basis for dynamic response analysis and structure design of worm transmission system.
