摘　　要：运用Pro/E对圆弧圆柱蜗杆进行三维实体建模,通过STP格式将其导入有限元分析软件ABAQUS中进行预处理。采用Lanczos求解器对蜗杆进行模态分析,提取了蜗杆的前八阶固有频率及振型,分析了振动幅值随固有频率变化的趋势。同时,通过改变蜗杆的材料属性,探究不同材料对固有频率的影响。所得结论为分析蜗轮蜗杆减速器的动态特性分析提供了理论依据。The article used Pro/E to model the arc-contact worm and analyzed the modal with LANCZOS Solver in the ABAQUS. The initial eight order natural frequency and modes are obtained. The changing tendency of vibration amplitude with the natural frequency was analyzed. The influences of different material to the natural frequency are researched, and the result offers the theory to the dynamic analysis of theworm gear reducer.
