摘　　要：齿轮在传动过程中会产生弹性变形和微小故障的振动问题。建立了多级齿轮传动的虚拟样机,并在二级直齿轮传动刚体动力学模型中对传动齿轮引入柔性体,分别对正常模型和齿面磨损故障模型两种工况进行仿真,得到的仿真信号与实测信号相对比,验证了模型的准确性。提出了一种基于希尔伯特-黄变换(HHT)信号处理方法,将仿真信号进行一维级联组合形态学滤波消噪和希尔伯特-黄变换,准确识别出齿面磨损故障,所得结果与理论计算值的对比验证了方法的可行性。Gearbox in the process of transmission may cause elastic deformation and vibration of incipient fault.A virtual prototype of multistage gear transmission,which transmission gear was defined as flexible body,was set up to simulate two working conditions,abrasion condition tooth face and regular one,separately.The accuracy of dynamic model was confirmed by the signals from simulation.A signal processing method was proposed to identify the fault of tooth surface abrasion by using Hilbert-Huang Transform(HHT)after using one dimensional cascade combination morphology filtering for noise reduction.The feasibility of method was validated by comparing results of simulation with theoretical calculation values.
