Raymond R. McHenry

Professional Experience

1994 to date. Research Consultant, McHenry Software, Inc. Cary, North Carolina. Research and development of vehicle simulation and accident reconstruction computer programs and tools

1980 to 2008, retired. Staff Scientist, McHenry Consultants, Inc., Cary, North Carolina. Technical Duties: Investigation of highway accidents. Application of analytical and experimental techniques to the reconstruction of vehicle and occupant dynamics in highway collisions. Evaluation and analysis of vehicle defects and failure modes. Performance of research related to highway safety.

1978 to 1980. Staff Scientist, Research Engineers, Inc., Research Triangle Park, North Carolina. Technical duties: Application of analytical and experimental techniques to the reconstruction of vehicle and occupant dynamics in highway collisions. Evaluation and analysis of vehicle defects and failure modes. Performance of research related to highway safety.

1961 to 1978. Staff Scientist, Calspan (formerly Cornell Aeronautical Laboratory, Inc.), Buffalo, New York. Technical duties: As a Staff Scientist with Calspan Field Services, Inc., and previously with Calspan Corporation, Mr. McHenry was responsible for the technical direction of a variety of research projects related to the improvement of highway safety. He was involved in the application of analytical and experimental techniques to the problems of occupant protection in collisions and he analyzed automobile dynamics in single vehicle accidents and in violent evasive maneuvers. He also served as the Principal Investigator on the development of techniques for analytical reconstruction of highway accidents [Simulation Model of Automobile Collisions (SMAC) and Calspan Reconstruction of Accident Speeds on the Highway (CRASH)].

Mr. McHenry developed techniques for study of physical criteria for roadside structures and cross-section designs by mathematically modeling the dynamics of single vehicle accidents [Highway Vehicle Object Simulation Model (HVOSM)]. He performed analyses and developed computer simulations of the dynamics of automobile braking and of the ride and steering dynamics of the Westinghouse Transit Expressway Vehicle. He studied advanced technology applicable to highway transportation in the Boston-Washington Corridor in 1980. He developed a nonlinear mathematical model of the automobile crash victim and mathematical models of highway guardrails and test vehicles for simulation of impact.

1960 to 1961. Technical Advisor, American Machine & Foundry Company, Greenwich, Connecticut. Technical duties: Mr. McHenry was technical advisor on the design of vehicles for aircraft cargo loading (Air Force 463L System).

1956 to 1960. Senior Design Engineer, Ford Motor Company, Dearborn, Michigan. Technical duties: Senior Design Engineer and Project Engineer on programs involving experimental hydropneumatic suspension vehicles, air suspension vehicles, and stroke-sensitive shock absorber design and development. Member of the Ford Advanced Ride and Handling Committee.

1953 to 1956. Chrysler Corporation, Highland Park, Michigan. Technical Duties: Participated in various experimental suspension and chassis component design and development programs. He also served as a mathematics instructor in calculus, analytic geometry and algebra (Lawrence Institute of Technology, Chrysler Institute, Detroit).
