APPARATUS AND METHOD FOR MEASURING DYNAMIC CHARACTERISTICS OF JOINT SURFACE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for measuring dynamic characteristics of a joint surface, configured to join a plurality of components in finite-element-modeling an object formed by joining the plurality of components and to accurately identify variables to be applied to a spring element and an attenuation element indicating joint characteristics.;SOLUTION: An apparatus 10 for measuring dynamic characteristics of a joint surface comprises: surface pressure applying means 13 which holds a second test piece 12 with a first test piece 11, and applies preset surface pressure to a joint surface between the first and second test pieces 11, 12; exciting force applying means 14 which applies preset exciting force to the second test piece, while the joint surface is applied with the surface pressure; relative displacement measuring means 15 which measures relative displacement between the first and second test pieces 11, 12 when the exciting force is applied; and processing means for identifying variables to be applied to a spring element 51 and an attenuation element 52 for each surface pressure applied, on the basis of the applied exciting force and the measured relative displacement.;COPYRIGHT: (C)2014,JPO&INPIT
