The invention relates to a multiple resonance multi-shaft vibration aging device comprising vibration exciters, vibration excitation blocks and spring damping assemblies, wherein the vibration exciters are arranged on the vibration excitation blocks, the spring damping assemblies are arranged at two sides of the vibration exciters and are connected with the vibration excitation blocks, and the vibration excitation blocks are connected with multi-shaft parallel connection workpieces. A realization method of the device is as follows: different vibration excitation frequencies are generated by all the vibration exciters and simultaneously act on the vibration excitation blocks, and multiple resonance frequencies far higher than the original vibration excitation frequencies of all the vibration exciters are generated; the vibration excitation blocks act on the parallel connection workpieces at the multiple resonance frequencies close to the inherent frequencies of the multi-shaft parallel connection workpieces; when the inherent frequencies of the multi-shaft parallel connection workpieces and the vibration excitation frequencies of all the vibration exciters are in a plurality of linear combination relationships, the parallel connection workpieces generate main resonance and corresponding dynamic stress to eliminate the residual stress of each shaft. By using the multiple resonance multi-shaft vibration aging device, the problem that the residual stress can not be eliminated effectively because the vibration excitation frequencies of the traditional vibration exciters are smaller than the inherent frequencies of the parallel connection workpieces can be solved, and the production efficiency can be increased.
Description
technical field [0001] The invention relates to a vibration aging device in the field of mechanical processing and a realization method thereof, in particular to a multi-resonance multi-axis vibration aging device and a realization method thereof. Background technique [0002] Vibration aging is an important method to eliminate the residual stress of the workpiece. Compared with natural failure and artificial thermal aging, vibration aging has the characteristics of no pollution, less investment, high efficiency, and saving space, time and energy. In the process of avoiding thermal aging There are also benefits in terms of possible oxidation of the workpiece, phase transitions and uneven heating of the workpiece leading to fission or new stresses during cooling. The vibration exciter of the current vibration aging device is limited by the motor speed and the maximum speed of the eccentric wheel mechanism, and its excitation frequency is less than 200Hz. Therefore, the vibrat...
