METHOD OF DESIGNING PARTS, PARTS DESIGNING DEVICE, COMPUTER SOFTWARE AND COMPUTER READER OF DATA CARRIER Russian patent published in 2010 - IPC B21D22/00 G06T17/40 G01M19/00 

FIELD: process engineering.

SUBSTANCE: set of invention relates to machine building and can be used in CAD. During the first design stage computer is used to analyse forged part proceeding from forged part shape, billet clamping force, friction factor, material tensile strength, yield stress, relationship between strain and stress and sheet thickness as forging conditions for computation distribution of sheet thickness and strain distribution after forging in forged part. During the second stage operating conditions are analysed proceeding from sheet thickness distribution, strain distribution after forging forged part shape distribution as parametres of the forged part stage for computation of operating properties of forged part. Note here that computations made during both stages are repeated preset number of times with varying at least one condition of gorging to define optimum forging condition that allow obtaining maximum value or target value of operating characteristic. Proposed method is implemented using computer and data carrier reader.

EFFECT: optimum design to obtain required operating characteristics.
