摘　　要：橡胶履带轮一般依靠橡胶履带的驱动齿和驱动轮的驱动销啮合传递动力,当驱动齿受到过大载荷或载荷冲击时容易受到破坏,因此,针对驱动齿应力分布进行了数学建模和计算分析。首先,根据橡胶履带轮结构参数和传动原理建立驱动齿齿形方程,应用改进Powell算法确定映射参数,结果表明,采用该方法得到的映射齿形映射精度为0. 12%,有效提高了映射精度;然后,基于复变函数法建立了驱动齿应力变形计算数学模型,分析了不同啮合位置下驱动齿应力分布规律;最后,以计算工况为边界条件,利用Abaqus对分析结果进行仿真验证,结果证明,仿真结果与计算数据最大误差约11. 76%,该数学模型能够较好地应用于驱动齿应力分析。该计算仿真结果可为驱动齿的结构内部优化和局部胶料改进提供理论依据。The rubber track wheel generally transmits power by the engagement of the driving teeth of the rubber track and the driving pin of the driving wheel. The driving teeth are likely to be destroyed when they are subjected to excessive load or load impact. The mathematical model and calculation analysis for the driving tooth stress distribution are carried out. Firstly,based on structure parameters and transmission princi ple,the drive tooth profile equation is established and determining mapping parameters by the improved Pow ell algorithm. The optimization results show that the accuracy of the mapping tooth profile obtained by this method is 0.12%,which effectively improves the mapping accuracy. Secondly,based on the complex function method,the mathematical model for stress and deformation is established,and the stress distribution laws un der different meshing positions are analyzed. Finally,the calculation conditions are set as boundary condi tions,and the analysis results are verified by using Abaqus software. The simulation results show that the max imum error between the simulation data and the calculation data is about 11.76%,so the mathematical model can be applied to the analysis of the driving tooth stress. This calculation results can provide theoretical basis for structural optimization of driving teeth and improvement of local rubber materials.
