摘要

PPROBLEM TO BE SOLVED: To provide a structural analysis method which enables calculation in a shorter time with regard to the structural analysis of a member in which a weld is generated by injection molding. PSOLUTION: A strength analysis method for evaluating the member to be injection-molded, a plurality of values of strength includes the step (S1) for obtaining shape information indicating the shape of the member, the step (S2) in which the member is divided into a plurality of elements on the basis of the shape information to produce element information indicating each divided element, the step (S3) in which the thermal characteristic value of each element of the member is calculated by carrying out thermal analysis by the use of each element indicated by the element information when heat is transmitted from a gate for charging a material into a mold to produce thermal characteristic information including the thermal characteristic value, the step (S4) in which it is determined whether the thermal characteristic value of each element satisfy prescribed conditions or not, and an element satisfying the prescribed conditions is specified as a weld position where the weld is generated, and the step (S5) in which the strength of the member is converted into strength in consideration of the effect of the weld in comparison with a weld position.

要解决的问题:提供一种结构分析方法,该方法能够在较短的时间内对通过注射成型产生焊接的构件的结构分析进行计算。解决方案:一种用于评估待注塑部件的强度分析方法,其中,多个强度值包括用于获得表示部件形状的形状信息的步骤(S1),以及用于确定部件形状的形状信息的步骤(S2)。根据形状信息将构件划分为多个元素,以产生表示每个划分元素的元素信息,在步骤(S3)中,通过对构件进行热分析来计算构件的每个元素的热特性值。当从用于将材料充入模具的浇口传热以产生包括热特性值的热特性信息时,使用由元素信息表示的每个元素,在步骤(S4)中,确定是否存在热特性值。每个元素是否满足规定条件,并且满足条件的元素被指定为产生焊缝的焊接位置,在步骤(S5)中,考虑到与焊接位置相比的焊接效果,将构件的强度转换为强度。
