摘　　要：为减小齿面磨损量、改善其传动性能,提出了一种基于Sine-SSA-BP模型的复合修形设计方法,以探明修形设计对齿面磨损的影响。依据Archard磨损模型求解出齿面磨损量,以磨损阈值和许用磨损量为判据进行齿面重构和修形设计,并分别推导了新齿面坐标方程;同时,利用Sine混沌映射改进的麻雀搜索算法(Sparrow Search Algorithm,SSA)优化反向传播(Back Propagation,BP)神经网络,与传统BP模型进行对比,验证Sine-SSA-BP模型的精度,以此表征修形参数与磨损量之间的隐式关系,并进一步探究修形参数影响下齿面磨损量的分布规律;最后,迭代求解得出最佳修形参数值并进行齿轮修形设计,对比分析修形设计对齿面磨损量的影响。结果表明,复合修形设计后的齿面接触状态得到显著改善,磨损量明显下降。本文方法有利于减小齿轮早期磨损失效概率,可为齿轮抗磨设计和参数优化提供理论参考。To reduce the wear of gear tooth surface and improve its transmission performance,a composite modification design method is proposed,which is based on the Sine-SSA-BP model and used to verify the influ⁃ence of modification on gear wear.According to the Archard wear model,tooth wear is calculated.The threshold and the permissible gear wear are used as the criteria to reconfigure and modify the gear tooth.The new tooth surface coordinate equations are derived respectively.Moreover,the sparrow search algorithm(SSA)improved by the Sine chaotic mapping is used to optimize the back propagation(BP)neural network,and the accuracy of Sine-SSA-BP is verified by comparing it with the traditional BP,so as to characterize the implicit relationship between the modification parameters and the gear wear.The distribution law of gear wear under the influence of modification parameters is further investigated.Finally,the optimal modification parameters are obtained through the iterative solution,and the composite modification design is carried out.The influence of modification design on the gear wear is compared and analyzed.The results show that the contact state of the tooth is signifi⁃cantly improved,and the gear wear is significantly reduced after the composite modification design.This method is conducive to reducing the early wear failure probability of gears and can provide theoretical reference for the anti-wear design and parameter optimization of gears.
