Pam-Comfort Helps Renault Design New Seat
Renault has used ESI's Pam-Comfort system for the preliminary design of a new seat. ESI's Pam-Comfort software offers a scalable and customised solution dedicated to virtual manufacturing and virtual testing (static and dynamic) of the soft parts of a seat. Virtual seat prototyping consists of several chained simulated steps ranging from seat manufacturing and occupant static seating, to occupied seat NVH (noise and vibration), where the stresses resulting from each step are needed for the next one. The chaining is necessary to accurately predict the behaviour of the seats under numerous loading conditions (trimming, dummy loading, various human anthropometries and vibrations) and for various design changes (materials and shape). At Renault, where the full virtual seat prototyping methodology is being deployed, an important step after the preliminary design of a new seat is the virtual testing of the dynamic comfort performance using Pam-Comfort. To accurately predict seat com...
