Due to the complex structure and wide excitations of range extender, the misfire and stator short-circuit coupling fault is easy to occur. Therefore, it is necessary to study the coupling fault mechanism of range extender, analyze the cause of the fault and the evolution law of fault, and diagnose the coupling fault through coupling fault characteristics ultimately. In this paper, a range extender is taken as research object. By establishing a nonlinear dynamic model and using Runge-Kutta method with variable step size, the dynamic response characteristics of system under different working conditions are analyzed to study the single fault and coupling fault mechanism. Then through the finite element analysis and practical experiments, the feasibility of coupled fault diagnosis is verified. The results show that when misfire fault and stator short-circuit fault occur at the same time, the vibration intensity of coupling fault is greater than that of single fault, and the 0.5- and 3.0-order harmonic amplitudes of horizontal vibration speed increase with the coupling fault.
