Mr. Struble specializes in automotive and heavy truck accident reconstruction, and he also has expertise in vehicle structural performance, restraint system analysis, and rollover initiation. Within the area of accident reconstruction, Mr. Struble is proficient in crush energy analysis in a wide variety of crash modes, from vehicle-to-vehicle side impacts to pole impacts to underride/override collisions. Mr. Struble has evaluated vehicle performance in real-world collisions with respect to the Federal Motor Vehicle Safety Standards. He is also certified to download and analyze air bag control modules using the CDR download system and is trained in downloading engine data from commercial vehicles.
Prior to joining Exponent, Mr. Struble worked at the National Highway Traffic Safety Administration, where he worked on the development of the Rollover New Car Assessment Program. After leaving the NHTSA in 2003, Mr. Struble worked as a consultant with Struble-Welsh Engineering, Inc., providing accident reconstruction services in negligence and products liability litigation cases. Mr. Struble has worked on a wide variety of cases that required subject and exemplar vehicle inspections, site inspections, analysis and reconstruction presentations, simulation, and expert testimony. He has worked for a variety of different clients that include manufacturers and Tier I suppliers. Through the course of his work at the NHTSA and in his consulting practice, Mr. Struble has gained experience in test design and analysis, from a component level to full-scale vehicle testing.
Mr. Struble’s work has been published by SAE and ASME, in the areas of accident reconstruction and restraint system analysis. One of his papers, “Side Impact Structural Characterization from FMVSS 214D Test Data,” won SAE’s prestigious Arch T. Colwell Merit Award, which recognizes papers of outstanding technical merit and original contributions to mobility science. Another of his papers was selected for SAE’s Transactions, a repository of superior SAE technical publications.
