Mr. Larson addresses issues related to accident reconstruction and vehicle dynamics, including testing and analysis of vehicle handling, vehicle stability, advanced vehicle safety systems, and vehicle crash testing. Mr. Larson also has expertise in occupant vibration exposure and ride quality, and vehicle fire causation. His range of experience includes working with automobiles, light trucks/SUVs, heavy trucks, construction/industrial equipment, ATVs, motorcycles, and locomotives.
Mr. Larson has extensive experience investigating rollover crashes and analyzing various aspects from the causes of loss of control through reconstructing the rollover sequence. During his time with Exponent Mr. Larson has conducted numerous vehicle roll-over tests, both to standardized test procedures and by developing unique ways of recreating accident specific characteristics. He has extensive experience working with and analyzing the use of computer applications in vehicle dynamics and accident reconstruction.
Mr. Larson has evaluated vehicle stability, crashworthiness, and occupant protection issues on a wide variety of vehicles. The evaluations involve mechanical design analysis, biomechanics, and understanding of the use of standardized testing for evaluating occupant protection. He has conducted numerous evaluations of the vibration and impact exposure on railroads across the country and a variety of commercial vehicles. He approaches reconstruction using traditional accident investigation and calculation techniques, but also brings extensive crash testing and computer simulation experience. He is experienced in conducting vehicle handling/characterization analyses with both on-road and off-road vehicles, and in evaluating driver response issues in vehicle handling and accident avoidance scenarios.
Mr. Larson has developed unique test methodologies and has experience conducting and developing standardized tests, as well as evaluating vehicle safety issues through database analysis. This includes Mr. Larson’s experience in developing the standards for heavy truck occupant protection and his involvement on SAE committees. He has experience with test fixture design, instrumentation, data analysis, signal processing, vibration measurement, sound level monitoring, and component testing.
Additionally, he has researched and presented on issues related to ADAS and autonomous vehicles.
