|
Abstract:
为了改善减速器中齿轮传动部分的工作状态，避免其在传动系统中因激励而产生共振。首先，建立齿轮传动的三维模型并导入ANSYS Workbench进行有限元模态分析；其次，采用赫兹理论对齿面强度进行计算，验算仿真受力正确性；最后，研究啮合时不同网格划分对瞬态结构应力的影响，分析其不同参数下的变化规律，为后续振动特性分析与齿轮的动力学特性分析提供理论支持。
In order to improve the working state of the gear transmission part in the reducer and avoid its resonance due to excitation in the transmission system, firstly, the 3D model of the gear transmission was established and imported into ANSYS Workbench for finite element modal analysis. Secondly, the Hertz theory was used to calculate the strength of the tooth surface, and the correctness of the simulated force was checked. Finally, the influence of different meshings on the transient structural stress during meshing is studied, and the variation law under different parameters is analyzed, which provides theoretical support for the subsequent vibration characteristics analysis and the dynamic characteristics analysis of gears.
