摘　　要：为获得体积小、结构紧凑合理、承载能力大的端面啮合蜗杆副,应用有限元和弹性力学理论,建立端面啮合蜗杆副的三维有限元模型;利用动力学和模态分析理论,进行模态分析,获得端面啮合蜗杆副固有频率、主振型等模态参数;根据WORKBENCH响应面法,运用多目标遗传算法,以端面啮合蜗杆副的第一阶固有频率和体积为优化目标,完成多尺寸的优化设计,获得结构紧凑合理、承载能力大的端面啮合蜗杆副。分析结果表明,在保证端面啮合蜗杆副传动性能不下降的前提下,体积减少15.5%。研究结果为端面啮合蜗杆副的模态试验、瞬态分析及加工制造提供依据。In order to obtain the end face engagement worm gear （hereinafter called as EWG）, which has the features of small volume, rational structure and large bearing capacity, by using the finite element and elasticity theory, the threedimensional finite element model of EWG is set up. Based on the theory of dynamics and modal analysis, the modal parameters for natural frequency and main vibration mode of EWG are obtained. At last, based on the response surface method of WORKBENCH, taking the first natural frequency and volume as optimization objective, the rational compact structure and large bear capacity of EWG is obtained by multidimensional optimization design. The analysis results show that the volume of the worm reduced by 15.5% , which guarantee the dynamic property. The results provide basis for modal test, transient analysis and process and manufacturing.
