Title:
有限要素法を用いた衝突解析装置、衝突解析方法および衝突解析プログラム
Document Type and Number:
Japanese Patent JP4826311
Kind Code:
B2
Abstract:
To make it possible to collision analyze using finite element method while considering the spot welding breakage while making the displacement at the time of the spot welding breakage is coincident with the result of experiment.
Displacement L0to the load P0at th time of breakage of the spot welding is measured by the experiment using a jig, the load Pvirtualcorresponding to the displacement L0 at the time of breakage of spot welding measured in the experiment is derived from the relation R2 between the load F in the welded part and the displacement L derived from the collision analysis using the finite element method, and the load Pvirtualis set as the welding breakage limit. The collision analysis of the spot welding structure for a vehicle using finite element method is made while considering the spot welding breakage from the limit of spot welding breakage.
