摘　　要：为研究齿轮传动系统动力学稳健性优化设计方法,以高速人字齿轮传动系统为研究对象,首先,建立其动力学分析有限元模型,利用模态叠加法计算箱体振动加速度;然后,选取齿轮箱上7个主要结构参数作为动力学优化的设计变量,以箱体表面振动加速度均方根值最小作为优化目标,通过6σ稳健性优化方法得到最优设计变量;最后,在优化后的样机上开展振动特性实验.结果表明:优化前后齿轮箱体均不会发生共振,优化后振动加速度均方根值降低26.1%以上,优化后结构的可靠度可达97.1%以上.To investigate a robust optimization design method for the dynamic performance of gear transmission systems,a high-speed herringbone gear transmission system is selected as the research object.First,a finite element model for dynamic analysis is established,and the vibration acceleration of the gearbox housing is calculated using the modal superposition method.Seven key structural parameters of the gearbox are chosen as design variables for dynamic optimization,with the objective of minimizing the root mean square(RMS)value of the surface vibration acceleration.The optimal design variables are obtained through the 6σrobust optimization method.Finally,vibration characteristic experiments are conducted on the optimized prototype.The results indicate that the gearbox housing does not experience resonance before or after optimization,with the acceleration reduced by more than 26.1%after optimization.Furthermore,the reliability of the optimized structure exceeds 97.1%.
