Passenger comfort
Perform End-to-End Virtual Prototyping for seats including:
- Seat manufacturing
- Occupant static comfort
- Occupant safety
- Occupant vibratory comfort
- Occupant thermal comfort
Using a digital mock-up of the seat and of the occupant, the comfort application within Virtual Performance Solution predicts some detailed information related to Seat Manufacturing and Performances, taking into account the complex physics of materials (foams, fabrics, and plastics), the multiple contacts (between lumbar support and foam, between foam and cover, between cover and occupant), and the time-dependent processes (standardized sitting processes of dummies). The physical parameters resulting from each stage of the chain (positions, deflections, strains and stresses) are used as an input to the following one, in order to ensure a high level of precision, whatever the seat and the anthropometry of the occupant.
The foaming process enables to estimate the filling time, the location of weld lines and potential issues such as air traps. The foam density distribution can be used as input for the next stage in order to improve the accuracy.

The sewing process enables to detect early in the design process possible craftsmanship issues such as cover wrinkles and bridging gaps. The cover and foam strains resulting from that stage can be used as input for the next stage.

PAM-COMFORT scope covers all types of occupants: comfort and crash dummies, as well as human models from different anthropometries and populations.
Human models developed in partnership with Hyundai Motor Company.

“The developed models and methodology allow the computation of predictive results, using only physical parameters and without any tuning of filtering. This good correlation between simulations and tests confirms the ability to assess the riding seat comfort in a full virtual process.”
