3 Day McHenry Seminar on Crash Reconstruction

Post by MSI »

Since 1994 we have been providing 3-5 days technical training on Crash Reconstruction Techniques and software. Since early 2020, due to the pandemic, we have provided online training seminars (Zoom, etc.) for companies and small groups.

  • Our team is Raymond & Brian McHenry who have designed and administer the courses.
  • We administer and grade a test to attendees after each seminar and certificates are only provided to those that pass.
    • Here is a sample test we give at the end of a 3 day seminar.
Please contact training@mchenrysoftware.com for a quote and schedule some training for your company/group today!
Our training is based on our 2008 book which we provide to all attendees as part of the seminar.
  • McHenry Accident Reconstruction 2008
    by Raymond R. McHenry & Brian G. McHenry
    • "The purpose of this book.. .is to return the focus of attention to the fundamentals of accident reconstruction and to the status of scientific progress in this field. This book is a collection of useful information related to the theoretical bases of reconstruction calculations"
    ~207 pages, Table of Contents
    Individual seminars are tailored to training needs and topics requested
    The final test is also tailored to subjects covered during the training.
    • McHenry Accident Reconstruction contains detailed analysis and hand calculation techniques for all aspects of Accident Reconstruction.
    The introduction to the book provides the launch point for our 3-5 day seminar:
    • Introduction
      • The origins of many of the analytical procedures and much of the technical information presented herein are research programs that were predominantly government-sponsored and were aimed at the improvement of highway safety. A major objective in research programs related to reconstruction was to achieve refinements in the definitions of occupant exposures that occur in actual highway collisions and to combine them with detailed measures of the corresponding injuries.
        Reconstruction research is seen as being essential to progress in the development of injury countermeasures. The injuries that occur in actual accidents can constitute highly valuable measures of the tolerances of live humans in actual collision exposures and of the effectiveness of protective systems and design features. Such measures are beyond the capabilities of laboratory experiments which must use human volunteers and/or surrogates. Thus, the reconstruction approach can yield unique and beneficial information from analyses of actual injury producing accidents.
        At the present time, government support of highway safety research, in the form of accident reconstruction, is greatly diminished. In fact, there is a substantially greater amount of related development activity in the litigation arena where the objectives and the needs are quite different.
        • For government research and statistical studies of injuries in accidents, the average errors of a large sample of applications of a specific reconstruction technique are the important measures.
        • For litigation crash reconstructions, which are focused on evidence interpretation in a single accident event, the maximum possible errors in the reconstruction results must be recognized and acknowledged.
        The fact that a specific technique has been used by a government agency must not serve without challenge as the basis for claims of appropriateness and/or acceptable accuracy in the non-statistical application to an individual litigated accident.

        Computer Programs

        With the rapidly increasing capabilities and capacities of computers, there is a growing inventory of commercially available, special purpose computer programs that deal with a wide variety of technical topics. This trend is clearly present in the field of highway accident reconstruction.
        Since many of the applications of accident reconstruction programs are aimed at courtroom presentations, recent emphasis in this field is being placed on the development and use of high resolution digital graphics as opposed to the development of more accurate reconstructions. Such graphics capabilities permit the creation of animations in which anything imagined can be made to look very real. An example of the recent emphasis in the field on image over substance is the relatively widespread use of spline fits to control high-resolution animation sequences which are sometimes inconsistent with Newtonian dynamics. As scientists, engineers and accident reconstructionists, we should not let the unlimited possibilities of making anything look real (with animation) obscure our duty to perform a careful and detailed engineering analysis while also continually testing and evaluating the applied techniques, including computer programs, to achieve the most accurate reconstruction possible.

        McHenry Software is, of course, involved in the development and marketing of accident reconstruction and graphics computer programs. However, the purpose of the McHenry book and McHenry Crash Reconstruction Seminars is to return the focus of attention to the fundamentals of accident reconstruction and to the status of scientific progress in this field.
        The book and seminars are a collection of useful information related to the theoretical bases of reconstruction calculations.
