Title:
METHOD FOR PREDICTING DEFORMATION QUANTITY DUE TO CONTRACTION OF MOLDED ARTICLE, AND DEVICE FOR SAME
Document Type and Number:
Japanese Patent JP2008254396
Kind Code:
A
Abstract:
To provide a method for easily and precisely predicting the deformation quantity of a molded article deforming due to contraction and a device for the same.
In the method for predicting the deformation quantity due to the contraction of the molded article 10, the supporting point P of bending moment M is obtained according to the contraction rate distribution of a molded material constituting the molded article 10 and the deformation quantity is predicted using the supporting point P. In this case, it is preferable that the bending moment M is obtained using the supporting point P and the deforming quantity is predicted using the bending moment M. Further, it is preferable that the molded article 10 is an injection molded article.
