Autoliv, the world's largest manufacturer of automotive safety equipment, has developed side-curtain airbag systems by using MSC Dytran to similate the dynamic events that occur during inflation, such as gas flow and enclosure impact stiffness. MSC Dytran provides Autoliv with an effective tool to study OOP (out-of-position) scenarios, enabling engineers to identify and quantify the impact of numerous design variables. The software provides real value in terms of reducing the time and overall development effort required, compared to conventional prototype build and test methods.
Challenge:Simulating airbag deployment is a complex and labor-intensive process, including meshing of the material and folds, analysis of fluid flow, and dynamic stresses on the enclosure.
Solution:Using MSC Dytran, the engineers at Autoliv were able to pinpoint the key contributing variables and isolate them for optimization.
Benefits:The software provides real value in terms of reducing the time and overall development effort compared to conventional prototype builds and testing.
