【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。
[Abstract]:In order to obtain the worm pair with small volume, compact structure and large bearing capacity, the three-dimensional finite element model of the end meshing worm pair is established by using finite element method and elastic mechanics theory, and the theory of dynamics and modal analysis is used. Modal analysis is carried out to obtain modal parameters such as the natural frequency and the main mode shape of the end meshing worm pair. According to the WORKBENCH response surface method, the first order natural frequency and volume of the end meshing worm pair are taken as the optimization targets by using the multi-objective genetic algorithm. The multi-dimension optimization design is completed to obtain the worm pair with compact and reasonable structure and large bearing capacity. The analysis results show that the transmission performance of the end meshing worm pair is not reduced under the premise of ensuring that the transmission performance of the end face meshing worm pair is not reduced. The results provide the basis for modal test, transient analysis and manufacture of the end face meshing worm pair.
