This paper presents a practical prototype knowledge-basedsystem, called IKMOULD, for mould design in the injectionmoulding process. It attempts to tackle the problem in apractical and integrative way, unlike the stand-alone andmathematical p...

A multi-step unfolding method (MSUM) is developed for blank design and formability pre-diction of complicated progressive die stamping part. In themethod, a finite elementmodelof the inverse approach (IA) is developed at a local area accord...

如果输入信号Ito元素是突然变了,从一个到另一个值,然后输出信号不会瞬间改变其新值。为例子,如果温度输入热电偶突然改变从25C到100C,之前一段时间会流逝e.m.f.输出完成改变1 mV 4 mV。...

Abstract The aim of this paper is to solve optimal design problems for industrialapplications when the objective function value requires the evaluation of expensivesimulation codes and its first derivatives are not available. In order to ac...

Abstract In an initial production planning stage, production material information in a building block is manually calculated by using data of parent ships and design experiences. Thus, the accuracy of the calculated information is low. To pr...
