ANALYTICAL SYSTEM USING FEM OPTIMUM ANALYSIS METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To solve the problem that action (the deformation of respective parts) and reaction (impact force) are wide apart from a real phenomenon when a positive analysis method is used for dynamic analysis, especially for the drop analysis of portable electronic equipment. SOLUTION: An optimum analysis method is selected and used for analysis by comparing an analytical time interval tex by the explicit method with an analytical time interval tim by the implicit method on the basis of the mesh size, Young's modulus and density of a model.
