Optimal Process Design in Non-Steady Metal Forming by the Design Sensitivity
설계민감도를 이용한 비정상상태 소성가공공정 최적 설계
Abstract
A new approach to process optimal design in non-isothermal, non-steady state metal forming is presented. In this approach, the optimal design problem is formulated on the basis of the integrated thermo-mechanical finite element process model so as to cover a wide range of the objective functions and design variables, and the derivative based approach is adopted for conducting optimization by design iteration. The process model, the formulation for process optimal design, and the procedures for the evaluation of the design sensitivity and for design iteration for optimization are described.
