Strength enhancement of 2010 Toyota Yaris Passenger Sedan driver seat as per Federal Motor Vehicle Safety Standards 207/210-A FEA approach

Problem statement: The purposes of this study are twofold: First, to check the failures in Finite Element model of 2010 Toyota Yaris Sedan driver seat, when loaded as per Federal Motor Vehicle Safety Standards 207/210. And second, to enhance the strength of failure component of seat to pass the standards 207/210. Approach: Toyota Yaris Sedan Passenger Vehicle driver seat model is taken from the National Crash Analysis Centre(NCAC) web. Seat is modeled and analyzed using Hypermesh and LS Dyna software´s respectively as per standards recommendations. The failure components we redesigned by analyzing various iterations to obtain feasible solution. Results: From the baseline results it is observed that failure in critical components such as Seat Tracks, Riser and Front Adjuster Link. Various design modifications were suggested such as increasing the track thickness, using high strength material for track or combination of both and providing additional locking J-bracket. Conclusion: The result obtained and discussed in this study can be applied in the driver´s car seat design and construction to ensure safety.
