Description
technical field [0001] The invention relates to a vibration aging device in the mechanical field, in particular to a bending-torsion coupling resonance type vibration aging device excited by an electromagnetic actuator. Background technique [0002] The dynamic stress generated by the bending-torsion coupling resonance is used to eliminate the residual stress of the shaft parts. In the implementation process, the torsional vibration excitation needs to be applied to the shaft. When the motor rotation frequency is equal to the difference between the bending natural frequency and the torsional natural frequency, the applied torsional vibration The excitation is equal to the torsional natural frequency. According to the bending-torsion coupling theory, the eccentric shaft will simultaneously excite the bending resonance, and the bending resonance and torsional resonance will strengthen each other to generate sufficient dynamic stress. The currently used torsional vibration exci...
