Success Story Abstract

The aim for Renault was to provide predictive results, including realistic mechanical seat modeling and a successful description of the materials’ complex dynamic behavior. To do so, Renault’s engineers built a detailed Finite Element (FE) model of one of their existing car seats using PAM-COMFORT and simulated its complex mechanical behavior, with non-linear materials, large deflections of the foam blocks and springs. This allowed them to assess the dynamic seat comfort in a full virtual process.

The Challenge

• Validate a new production seat model with simulation
• Evaluate all comfort issues related to an automotive seat (manufacturing, occupant seating, occupied seat vibration transmissibility)

The Story

“The models and methodology developed with PAM-COMFORT enable the computation of predictive results, using only physical parameters and without any tuning of filtering. This good correlation between simulation and test results confirms the ability to assess the riding seat comfort in a full virtual process.”
Jérôme Makala, Head of Comfort and Safety Research Department, Renault Group.

The Benefits

• Provide predictive and highly accurate results using Finite Elements
• Build a fully virtual preliminary design of a new seat and validate it with simulation
• Save on development costs and time
• Meet production targets
