Mégane III scored 5 stars at EuroNCAP with the help of Virtual Performance Solution Featuring PAM-CRASH

The Renault Group is one of the largest automakers in the world. Designing and THE CHALLENGE producing their own models since 1898, . Launch a vehicle with same comfort Renault is renown worldwide for its innovations and safety standards but with a in terms of design, safety, motor racing and reduced production cost and a lighter electrical . Body-in-White EXCELLING IN . Reduce CO emissions 2 INNOVATIVE AND . Use fewer physical prototypes than SUCCESSFUL CAR DESIGN for Mégane II in order to meet fi nancial Renault started using Virtual Performance Solution with PAM-CRASH in 2001 for structural crash and planning objectives simulation. Over the past few years, several Renault car models such as the Laguna III and the Scenic were validated by simulation with PAM-CRASH and obtained excellent results, both scoring fi ve stars at the EuroNCAP test. THE STORY The new Renault Mégane (also known as Mégane III) was not an exception to the rule. Renault was “Simulation is key to our project committed to earning the best possible score for this car model, as the Mégane is a fl agship vehicle line. Following the huge commercial success of Mégane II, Renault decided to refresh the Mégane development process. line, with a new look and design, while enforcing the comfort and safety standards the original PAM-CRASH allows us to identify model is known for. not only the behavior of standard Mégane III was launched in November 2009 in Europe, with a new design, and enhanced key features. vehicle defi nition but also the probability to improve our crash OUTSTANDING RESULTS AT EURONCAP CRASH TEST performance and to build virtually In line with Renault’s vision, the Mégane III scored 37/37 points and was awarded fi ve stars at every element that has an impact EuroNCAP crash test. The highest rating was granted for frontal crash testing, in part thanks to prior simulation results obtained with PAM-CRASH. on our decision-making.”

Eric Duguet, This high score for Mégane III is a turning point for Renault as they are the only CAE Body-in-White Manager, automaker to have ever earned eleven times fi ve stars at the EuroNCAP. Renault Group.

THE BENEFITS . Save costs and time in the development process by decreasing the number of real prototypes needed for physical tests . Get highly accurate results especially for strength, scattering and distortion Mégane III front crash simulation and EuroNCAP test effect Renault relied on virtual prototyping to validate the design of the Mégane III car model, before . Reduce overall CO emissions while 2 testing any physical prototypes. Virtual Performance tests with PAM-CRASH spanned Body-in- keeping the same standard of vehicle White modeling, structural crash analysis, as well as spotweld modeling. These also included safety robustness simulation with PAM-SAFE, ESI’s occupant safety analysis application within Virtual Performance . Simulate the entire car with Finite Solution, such as airbags release, belt pretentioners and occupant behavior under load cases. These safety simulations led to the development of the “SRP3”: the Third-generation Renault System for Elements (FE) modeling Restraint and Protection (Système Renault de Protection de Troisième Génération). The “SRP3” adapts the way protection equipment reacts according to the violence of impact during a crash.
