摘要

设计了一种内置式碟式太阳能方位角跟踪装置,建立了其方位角齿轮传动系统的UG三维模型,分析并确定了相应的约束条件及风载作用下系统的载荷,基于ANSYS Workbench仿真环境对齿轮传动系统进行了有限元分析,得到了齿轮传动系统的整体应力分布状况及其他重要特性,并用赫兹理论进行了验证。结果表明:通过有限元分析该齿轮传动系统最大应力为408.29 MPa且出现在惰轮齿轮啮合处,在齿根过渡曲线附近也存在明显应力集中,而蜗轮蜗杆所受应力波动较大,并利用赫兹理论对齿面接触强度进行分析计算并对有限元结果进行了验证。所作研究为双轴跟踪装置齿轮传动系统的设计及动态分析提供了一定的参考和依据。

Abstract

A built-in solar azimuth tracking device is designed. Then,its 3D model of azimuth angle gear transmission system is established by using UG,the wind load and boundary conditions are determined.The finite element analysis of the gear transmission system is carried out based on the ANSYS Workbench simulation environment. Finally,the integral stress distribution condition and other important properties of the gear transmission system are obtained and verified by using the Hertz theory. The results show that the maximum stress of gear transmission system is 408. 29 MPa by finite element analysis and appear in the idler gear meshing,near the dedendum transition curve is obvious exist stress concentration,and the stress fluctuation on worm and gear is bigger. The contact strength of the tooth surface is analyzed and calculated by using the Hertz theory. The results are verified by the finite element method. This study can provide a certain reference and basis for the gear design and dynamic analysis of gear transmission system of two-axis tracking mechanism.
