摘　　要：提出了一种基于复变函数法的驱动齿强度分析模型,能够准确反映复杂齿形及传动载荷对驱动齿应力应变的影响。运用改进Powell算法确定齿形映射参数,相较数值回归法和解析法,有效提高了齿形映射精度。基于驱动齿强度分析模型,利用Matlab软件计算分析了橡胶履带轮不完全啮合段驱动齿的应力情况,并建立了驱动齿啮合有限元模型对计算结果进行仿真验证。结果表明,基于复变函数法的驱动齿应力计算值与有限元仿真值最大误差约11. 76%,该模型能够较好地应用于驱动齿强度分析,也可为齿形优化和局部胶料改进研究提供参考。A model of driving tooth strength analysis based on complex variable function method was proposed, which can accurately reflect the influence of complex tooth shape and transmission load on stress and strain of driving tooth. The improved Powell algorithm was used to determine the tooth profile mapping parameters. Compared with numerical regression method and analytical method, this method effectively improves the tooth profile mapping accuracy. Based on the driving tooth strength analysis model, the stress analysis of the driving tooth under incomplete meshing condition was calculated by Matlab software, and the finite element model of the driving tooth meshing was established to verify the calculation results. The results show that the maximum error of the calculated value based on the complex variable function method and the finite element simulation value is about 11.76%. The model can be applied to the analysis of driving tooth strength. The analysis results can also provide a theoretical basis for tooth shape optimization and local rubber compound improvement.
