METHOD FOR PREDICTING DISTORTION WHICH OCCUR IN ADJACENTLY MOUNTED OBJECT TO BE PROTECTED DUE TO DEFORMATION CAUSED BY EXTERNAL FORCE EXERTED ON RESIN MOLD

摘要

PROBLEM TO BE SOLVED: To provide a method for predicting data on the amount of distortion useful for designing resin mold, which is the amount of distortion, which occurs in an adjacently mounted object to be protected, caused by an external force exerted on the resin mold, by simple hardware and easy and simple arithmetic processing. ;SOLUTION: A method for predicting the amount of distortion which occurs on an object to be protected mounted to a resin mold due to an external force exerted on the mold is formed of three processes. In the first process, a predetermined number of pieces of distortion data under predetermined conditions is obtained by a finite element method(FEM) by assuming minimum, intermediate, and maximum Young's moduli in a range predicted for application resin and further assuming the wall thickness of the resin mold and the interval between the resin mold and the internally sheathed object. In the second process, an relational equation ε=f(x1, x2) on the amount of distortion is obtained by performing regression-analysis processing on the distortion data obtained in the first process. In the third process, the amount of distortion under any given conditions which occurs in the object to be protected is predicted by substituting the wall thickness of the mold for x1 and the Young's modulus for x2 in the relational equation.;COPYRIGHT: (C)2000,JPO
