Visual-Environment Highlight of Visual-Seat: STAN Thermal Dummy

STAN is a thermal dummy to test thermal comfort and moisture management characteristics of automobile, truck, and airplane seating. This device is commercialized by Thermetrics® and some relevant information can be found here: https://thermetrics.com/products/manikin/stan/. In collaboration with Thermetrics, ESI developed a numerical model of the STAN dummy for the prediction of its thermal behavior. No humidity is managed in this version of the model. A process for the setup of the seating and the thermal simulations of the STAN dummy have been added in this version.

Visual-Environment Highlight of Visual-Seat: Sewing Simulation Guided Setup

Sewing simulations aim at assembling flat cover patterns and wrapping them around deformable foam block. This application exists in Visual-Seat for many versions as a set of toolboxes and functionalities enabling to set-up this type of input. This has been enhanced with a workflow gathering all tools and functionalities and proposing them in the right sequential order to provide some user guidance.

Visual-Environment Highlight of Visual-Seat: Foam Blocks Positioning

When assembling the different components of the seat, it may happen that the foam at rest is intersecting the frame and/or the suspensions. In order to remove those intersections, a simulation-based technique had been implemented previously by applying surface pressure on foam. Upon customer request, a new method has been added where the frame (and suspensions) can be scaled down and moved initially to retrieve progressively their size and position during simulation, when the contact with foam is active.

Delta T Offset For Bowing Effect in Assembly Process

In case of butt joint of two plates, in reality, there is an eccentricity e between the neutral phase of bending and the centre of the tendon force caused by the weld which causes the typical horse saddle of a butt welded flat plate.. A functionality Delta T Offset  has been developed in order to overcome the limitation due to the shrinkage methodology that cannot provide correct results for a butt joint with a non-symmetrical welding. With this new development, it will be possible to apply an offset value on the thermal loading between upper and lower surfaces of shell. In consequence, the horse saddle effect of a butt welded flat plate is produced with Assembly solution.
