| titleOfInvention | Characterization method of residual stress of aluminum alloy forging |
| abstract | The invention discloses a characterization method of residual stress of an aluminum alloy forging, which comprises the steps of establishing and optimizing a three-dimensional quenching-cold pressing finite element model of the forging, and obtaining data of residual stress field distribution after quenching and cold pressing of the forging; selecting characteristic points on the surface of an actual forging piece, and measuring actual residual stress values at the characteristic points; comparing the actual residual stress value of the characteristic point with the residual stress value of the characteristic point in the simulation model, and calculating the stress field correction coefficient of the region where each characteristic point is located; and writing a script program, and performing back calculation on the residual stress field of the region where the characteristic point is located based on the quenching residual stress field and the correction coefficient simulated by the forge piece, so as to obtain a more accurate quenching residual stress field. The method for calculating the integral residual stress field of the forge piece through the residual stress value of the forge piece characteristic point can quickly represent the size and the distribution characteristics of the residual stress of the forge piece in each processing state, and solve the problem that the residual stress of the forge piece cannot be monitored in time in the processing and production process. |
