Drive axle half shaft system is simplified to a single-span and double-cantilever rotor system, taking slant crack, bearing and tire sine excitation into consideration, 8-DOF dynamic equations are founded. Based on this model, the cracked half axle rotor system under high-speed drive condition is investigated by numerical simulation. The results indicate that: compared with uncracked half shaft system, cracked half shaft lateral vibration shows second harmonic generation, quadruplicated frequency and their combined frequencies with VC vibration frequency, and their corresponding amplitudes increase with the increase of crack depth. Therefore, slant crack information of axle shaft can be gained from the above three nonlinear factors.
