“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”.

Mr Jérôme Makala, Head of Comfort and Safety Research Department, Renault Group.

The use of Simulation-Based Design with PAM-COMFORT leads to some significant improvements in the seat development process:

- Drastic reduction of the number of trial-and-error loops on hardware seat prototypes in all development phases, leading to cost cuttings and time savings
  Troubles are identified very early in the seat design process, before any hardware prototype is built.
  The effects of small changes in design and of material production variations, are depicted by PAM-COMFORT  

- Improved seat quality and performance
  The designer better understands 3D effects and physical phenomena, with accesses to some information which cannot
  be measured on physical prototypes (meat-to-metal clearance, internal strains and stresses, detailed deflections...)
  A large number of comfort innovations are assessed, quantified and validated very early and quickly in the seat
  design process. 

- Improved synergies within a group, or with suppliers or customers
  The seat performance criteria are specified and evaluated very early, before building prototypes.
  The conflicting requirements related to seat design (comfort, safety, manufacturing, weight and size reduction
  …) are managed much earlier, and more easily.
  The quality of a wide range of other simulation-based, car design activities (ergonomics, crash and safety…) is
  enhanced by the accurate prediction of the occupant position and the detailed seat behavior, as an initial state for
   some other simulations.
