摘　　要：运用Pro/E和Kisssoft软件对ZC1蜗杆进行三维建模,并导入到ANSYS软件对其进行模态分析。为了研究多因素对ZC1蜗杆固有频率的影响,特分为两个实验组,第一组以约束状态的不同分为自由状态、约束状态和装配体状态,第二组以结构和材料的不同分为蜗杆齿形、轴的结构、蜗杆头数和材料。经过分析得出结论:自由模态不能代替实际工作状态,材料的弹性模量是影响蜗杆固有频率的最大因素。最后通过模态试验验证了装配体模型的正确性,为系统结构振动特性的描述及整机性能的优化提供了依据。Using the Pro/E and Kisssoft software modeling ZC1 worm, and importing them into ANSYS modal analysis. To study the effect of multiple factors ZC1 worm natural frequency,especially divided into two experimental groups,the first group of states with different constraints into a free state,bound state, the state assembly, the second group with different structures and materi- als, respectively research worm tooth structure, the worm first few material impact on the shaft. Finally, modal test to verify the correctness of the assembly model, provide the basis for the description and optimization of the overall performance of the vibration characteristics of the system architecture.
