Development of Failure Propagation Simulation for Airbag Door

摘要

We established the following simulation technology which makes high precision estimation of failure propagation possible. (1) Focusing on the airbag folding lines, we were able to realize high precision of airbag shapes of development by dividing the inside of a bag into virtual space and simulating the flow (2) With failure propagation simulation, we were able to realize high precision failure occurrence by reflecting the difference in strain rate, which is dependent on the portion, in the failure strain value.
