DROPPING IMPACT ESTIMATING METHOD, DROPPING IMPACT ESTIMATING DEVICE, DROPPING IMPACT ESTIMATING PROGRAM, AND MANUFACTURING METHOD OF ELECTRO-OPTIC PANEL

摘要

PROBLEM TO BE SOLVED: To provide a product having high impact-resisting performance at a low cost and in a short period of time. SOLUTION: An object of evaluation is divided into minute elements and modeled (step S101), and the model is modally analyzed to find the characteristic frequency of the object (step S102). Then, the model of the object is falsely let down to analyze the transient response of acceleration acting on the object (step S103). By executing impact response spectrum analysis with respect to the transient response of acceleration (step S104) to acquire acceleration with respect to each of frequency components. The acceleration of fall acting on the object is found from the acceleration with respect to each of the frequency components. If the acceleration is equal to or higher than a prescribed level, a modification model is prepared (step S106) to evaluate a fall impact value, and modification models are prepared until acceleration acting on the object becomes equal to or lower than a prescribed value.
