  • Method for calculating processing parameters for residual stress control by parameter inversion
    Patent number: 11501031
    Abstract: The present invention belongs to the field of processing residual stress, and discloses a method for calculating processing parameters for residual stress control by parameter inversion. This method comprises: (a) extracting a characteristic index reflecting the residual stress distribution characteristic from a residual stress distribution curve; (b) respectively presetting initial values of processing parameters for residual stress control, calculating an initial value of the characteristic index, and drawing curves of the characteristic index over the respective processing parameters to obtain respective fitted curves; (c) respectively establishing a relation formula between respective characteristic index increment of the processing parameters and the fitting curve; and (d) assigning the values and performing inversion calculation to obtain the required processing parameters.
