摘　　要：齿轮箱是复杂的动力学系统,其动力学演化过程难以刻画。本文在分析齿轮箱振动信号增量序列标度转折特性的基础上,利用三角函数关系式推导了标度区间起止点坐标之间的内在关系,由此建立了一种状态监测方法。将该方法用于监测实际齿轮箱的运行过程,并与常用的时域统计参数方法进行比较,结果证明了该方法的有效性和优越性。Gearboxes are complex dynamics system,and the dynamics evolving process of a gearbox is hard to describe.The scaling crossover property of increment series of vibration data of gearbox is analyzed,and on this basis,an intrinsic relation between coordinates of starting and ending points of a scaling range is deduced by trigonometric function.As a result,a novel method for condition monitoring of gearboxes is developed.Moreover,the method is applied to condition monitoring of a realistic gearbox,and comparing with the conventional time domain statistical parameter method,and the effectiveness and superiority of the developed method is proved by the result.
