摘　　要：针对齿轮啮合受到时变负载影响,引起齿面疲劳损失和冲击的问题,对齿轮动力学性能和修形进行了研究,首先利用ADAMS建立了刚柔耦合模型;然后基于不同修行方法,得到了修形前后的时变载荷曲线;最后应用ANSYS Workbench软件对多耦合齿轮传动系统进行模态分析,并利用瞬态动力学模块得到了修形前后齿轮啮合动态应力变化曲线。研究结果表明,在斜齿轮三齿和两齿交替啮合过程中,抛物线长修形传动性能优于圆弧短修形,可为齿轮动力学分析提供有效依据。Aiming at the problem of the gear mesh was affected by time varying loads which lead to gear surface fatigue damage and shock,the dynamic characteristics of gear and modification were carried out. The coupled model of rigid and flexible was built by ADAMS,and then the different time-varying loads were obtained based on different modification methods. Finally,modal analysis and dynamic stress behavior were carried out by ANSYS Workbench. The results indicate that the long parabolic modification is better than that of short arc modification in the process of alternating two and three pairs of teeth meshing of helical gear,which can provide the effective basis for gear dynamics analysis.
