JFOLD
JFOLD is a powerful software tool for simulation based airbag folding in Ansys LS-DYNA®. Accurately folded airbag models are an essential part of virtual vehicle testing and occupant safety. JFOLD enables fast but highly realistic airbag folding by providing an easy-to-use interface for many of LS-DYNA’s advanced functions.
Developed by JSOL Corporation, JFOLD is compatible with Oasys PRIMER. Simulations can be run locally or on a client’s existing hardware.
Airbag-folding simulation system for Ansys LS-DYNA
Airbag sewing simulation for the 3D airbag
An airbag is fabricated by sewing parts of cut out fabric. A three-dimensional (3D) passenger airbag is fabricated using 3D sewing. CAD for 3D geometry is not (generally) created. JFOLD can perform 3D sewing simulations for building 3D airbag models.
Airbag-folding process management using a flowchart (tree view)
JFOLD manages the complicated folding process using a flowchart, in a tree view. One step corresponds to one calculation for the folding simulation. Each calculation result can be transferred to the subsequent calculation to achieve the final folded geometry. Users can try various folding patterns with the branched folding processes.
View and modify the action types for tool setting
Set and modify the tool translation, rotation, folding, roll folding, and load arrangement. Users can see the action type determined for the tool.
Features & capabilities
Positioning and resizing with mouse operations
Users can easily move and resize the tool mesh using mouse operations.
Preview of the tool mesh behaviour
By using the preview feature, the animation of the tool mesh behavior can be displayed prior to a run as an LS-DYNA simulation.
