McHenry to Give 2014 ASME William Milliken Invited Lecture

Post by MSI »

Jan 2014: Raymond R. McHenry was invited to give the 2014 ASME William F. Milliken Invited Lecture
The Lecture is a part of the ASME AVT Conference, August 17-20, 2014 in Buffalo, NY
  • The William F. Milliken Invited Lecture
    • The ASME Vehicle Design Committee will measure candidates against some of the primary characteristics that defined Milliken's career. These include: deep curiosity, persistence to see complex tasks to completion, and a multi-disciplinary (and/or multi-industry) breadth of experience. He also demonstrated the importance of combining strong fundamentals and theory with experimentation and practical applications. Candidates should exhibit these characteristics through their original work on ground vehicles or vehicle engineering education.
The abstract of Mr McHenry’s presentation:
  • The Role of Vehicle Dynamics Simulation in Highway Safety Research
    by Raymond R. McHenry
    Monday August 18, 2014 10:30 AM to 12:00 PM
    ABSTRACT
    • Early analytical studies of the dynamic behavior of motor vehicles required an extensive use of simplifying assumptions to permit useful solutions of the governing equations based on linear theory or by means of analog computer simulations. Since the early 1960’s, rapid developments in digital computer technology have shifted the analytical challenge from the selection of simplifying assumptions to the definition of detailed and accurate equations and solution logic for realistic digital simulations.

      In highway safety applications, useful computer simulations of vehicle dynamics must clearly include all of the important non-linearities and be capable of dealing with abrupt discontinuities. At Calspan, in Bill Milliken’s Full Scale Division, our initial vehicle simulation development for highway safety studies (supported by the Federal Highway Administration (FHWA)) was a three-dimensional (3 D) simulation of vehicle responses to driver control inputs during interactions with highway and roadside geometrics and in collision contacts with roadside obstacles and structures.

      A related small Calspan spin-off project, in which the author worked closely with Mr. Milliken, was the “spiral jump” stunt of James Bond notoriety (presented herein because of the Milliken connection) which served as an attention-getting means of demonstrating the 3-D generality and validation of our vehicle dynamics simulation and enhancing Calspan's competitive position for future research contracts. Note that the performance of this project at Calspan would have been highly unlikely without the full support and influence of Mr. Milliken in persuading the upper levels of Calspan management. There clearly were concerns about liability. It is believed that Bill saw the “spiral jump” as an interesting and “fun” vehicle dynamics project.

      Subsequent research projects within the Full Scale Division of Calspan included digital accident reconstruction programs based on both two-dimensional (2-D) and 3-D simulations of vehicle dynamics in response to car-to-car collisions.
    BIOGRAPHY
    • Mr. McHenry has worked for over 50 years in the field of vehicle and highway safety research with particular emphasis on vehicle and occupant dynamics, computer simulations and accident reconstruction software. He 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 of highways and roadsides 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 ride and steering dynamics. He developed a nonlinear mathematical model of the automobile crash victim and mathematical models of highway guardrails and test vehicles for simulation of impact.

      Mr McHenry has authored over 70 technical papers and reports, many of which published his research on the use of computer techniques in the reconstruction of highway accidents, occupant kinematics and vehicle and guard rail performance. He is a recipient of the Crompton-Lanchester Medal and the Safety Award in Mechanical Engineering bestowed by the Institution of Mechanical Engineers in London, England. Both awards were related to demonstrated excellence in research on vehicle dynamics.

      He is currently a Board Member and research consultant with McHenry Software, Inc. From 1953 to 1960 Mr. McHenry was employed as a suspension and chassis design engineer in the automobile industry working for Chrysler (1953-1956) and Ford Motor Company (1956-1960). From 1961 to 1978 he worked for Calspan. In 2008 he retired from McHenry Consultants after having worked over 28 years in the field of highway safety research and litigation consulting with emphasis on analyzing and simulating vehicle dynamics and performing accident reconstructions.
Please plan to attend and we look forward to seeing you there! The ASME AVT Conference, August 17-20, 2014 in Buffalo, NY
