Abstract

The invention relates to an ultraharmonic-resonance vibratory stress relief device for a high-natural-frequency workpiece, which comprises a vibration exciter, a vibration excitation block, an adjustable damping and an adjustable nonlinear spring, wherein the vibration exciter is connected with the vibration excitation block, and the adjustable damping, adjustable nonlinear spring and vibration excitation block constitute a nonlinear vibration system. The vibration exciter acts on the nonlinear vibration system, so that the nonlinear vibration system generates ultraharmonic resonance at a frequency which is far higher than the original exciting frequency of the vibration exciter; and the vibration excitation block acts on the workpiece at an ultraharmonic resonance frequency approximate to the natural frequency of the high-rigidity workpiece, so that the workpiece generates main resonance and corresponding dynamic stress to reduce the residual stress of the workpiece. The invention can solve the problem that the high-rigidity workpiece can not be subjected to vibratory stress relief treatment.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a superharmonic resonance type vibration aging device for high natural frequency workpieces. Background technique [0002] Residual stress may be generated in the workpiece during hot and cold processing, and it is very important to eliminate residual stress. Commonly used methods for reducing residual stress include natural aging, thermal aging, and vibration aging. Natural aging has been gradually eliminated because of its long production cycle, large space occupation, difficult management, and inability to detect defects in the workpiece in time. At present, the thermal aging method is still widely adopted by factories, but the thermal aging method is labor-intensive and pollutes seriously. Compared with thermal aging, vibration aging can save energy and cost, especially it can save huge investment in building large annealing kilns. [0003] At present, vibration aging ...
