摘　　要：含故障齿轮非线性系统的全局性态分析是对齿轮正确故障诊断的状态依据,运用能够反映非线性系统复杂全局性态的简单胞映射方法,把故障齿轮非线性系统所处的状态空间转化为胞空间,对齿轮非线性系统在不同程度磨损故障状态下的动力系统的全局特性进行了分析,通过对比不同程度故障下系统的吸引域及其吸引胞,得到磨损故障齿轮非线性系统全局特性的变化规律,为齿轮非线性系统的故障诊断提供了另一种研究思路和方法。Global behavior of complex nonlinear gear system is a method for gear fault diagnostic.The simple cell mapping method,which is a numerical computing technology to solve the global behavior of complex nonlinear system,is used to global analysis of the dynamical behavior of nonlinear gear system under different degrees of wear faults.By transforming the state space of the nonlinear gear system into the cell space and comparing the domains of attraction and cell of attraction under different degrees of wear faults,the nonlinear system dynamic global developing rule of the gear wear fault is obtained,which offers a new method for the nonlinear gear system fault diagnosis.
