Abstract
The invention relates to a six-degree-of-freedom vibratory stress relief device. The device comprises six exciting branch chains, a movable platform and a stand, wherein the upper ends of the six exciting branch chains are connected with the movable platform through a second spherical pair, a fourth spherical pair, a sixth spherical pair, an eighth spherical pair, a tenth spherical pair and a twelfth spherical pair respectively, and the lower ends of the six exciting branch chains are connected with the stand through a first spherical pair, a third spherical pair, a fifth spherical pair, a seventh spherical pair, a ninth spherical pair and an eleventh spherical pair respectively; and the movable platform is used for mounting various workpieces for vibratory stress relief treatment. Through joint excitation of six exciters, the movable platform can produce spatial six-degree-of-freedom vibration, so that the workpieces can be excited to produce resonance of various frequencies and vibration modes, which comprises non-linear vibration such as combined resonance, subharmonic resonance, multiple resonance and the like; thus sufficient stress strain can be produced at each position inside the workpieces to effectively eliminate residual stress of the workpieces and obviously improve the vibratory stress relief effect.
