IMPACTOR MODEL AND IMPACT ANALYSIS SIMULATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an impactor model used for analyzing impact caused by input of striking, and an impact analysis simulation method.;SOLUTION: The impactor model includes: a rotary main body part model 110 which is rotated around an axis of rotation in a striking direction of a test target model by inputting an angular velocity; a head form part model 120 for inputting rotational striking to the test target model with rotational movement of the rotary main body part model; and an acceleration calculation element model for calculating an acceleration that is generated in the head form part model. The impact analysis simulation method includes the steps of: setting the test target model; setting the impactor model 100; setting a rotational striking condition of the impactor model; rotating the impactor model through the input of the angular velocity and executing an impact simulation of inputting the rotational striking to the test target model; and acquiring the acceleration through the acceleration calculation element model in the impact simulation.;COPYRIGHT: (C)2015,JPO&INPIT
