Abstract

The paper presents results of research for developing the method for vibrational relaxation of residual stresses in welded joints of complex spatial metallic structures. Working parameters and locations of vibrators are selected for considered a structure by simulating vibrational effects. Results of theoretical analyses are confirmed experimentally on complex spatial structures of large mass. Effects of vibrational relaxation indicate the applicability of proposed method for treating most complex structures.

Keywords: welded structure, residual stresses, relaxation, vibration
