electrical conductivity analysis method that takes into account the dynamic deformation of the object

摘要

PROBLEM TO BE SOLVED: To analyze electric conduction of a structural member that is used in a dynamic state with deformation.;SOLUTION: A transfer roller 2, or measuring object body, is divided into a plurality and finite number of elements to calculate a dynamic deformation shape and outputs a dynamic deformation model including coordinate information of respective elements when being deformed for every hour. The electric conduction when applying a voltage condition to a predetermined portion of the measuring object body is analyzed based on the dynamic deformation model, and a current amount flowing each element for every hour is calculated to find the dynamic electric conduction characteristics (a graph in Fig. 8(c)) of the measuring object body. Consequently, by using the two-step methods for specifying the dynamic deformation model of the measuring object body and analyzing the electric conduction using the dynamic deformation model as the object, the electric conduction characteristics at each time point can be found for the structural member that is used in the dynamic state with deformation.;COPYRIGHT: (C)2012,JPO&INPIT
