摘要/Abstract

摘要： 使用有限元方法研究直齿轮传动的啮合特性.基于APDL建立变位直齿轮副参数化有限元模型，采用显式动力学分析软件LS-DYNA对齿轮副啮合过程进行数值仿真，得到齿轮啮合产生的动态接触力以及动态传递误差，研究了齿轮变位系数对于齿轮啮合特性的影响，将动态传递误差与静态传递误差进行对比，分析了二者产生差异的原因.研究表明不同变位系数下，啮合频率都是主要的频率成分，其他频率成分的幅值受到变位系数的影响，接近固有频率的倍频幅值较大.静态传递误差与动态传递误差在时域和频域上都存在较大区别.

关键词: 变位系数, 直齿轮, 传递误差, 啮合特性, ANSYS/LS-DYNA

Abstract: Meshing characteristics of spur gear pair were researched using finite element method. Parametric finite element model of modified spur gear pair was built on the on the basis of APDL. Numerical simulation of gear meshing was performed via application of explicit dynamic software LSDYNA. Dynamic meshing characteristics caused by gear meshing such as dynamic contact force and dynamic transmission error(DTE)were obtained， and the effect of modification coefficient on dynamic meshing characteristics was studied. Static transmission error(STE)was compared with the aforementioned DTE. Finally the reasons for the difference between the DTE and STE were discussed. The results shown that under different modification coefficients， the meshing frequency is always the main frequency component. Other frequency components are affected by modification coefficient， and amplitude of the frequency component close to natural frequency is relatively larger. The STE is much different from the DTE on both time and frequency domains.

Key words: modification coefficient, spur gear, transmission error, meshing characteristics, ANSYS/LSDYNA
