SAFETY AND ACCIDENT RECONSTRUCTION
• Frontal Crash Mechanics −− Crash pulse, front loaded, rear loaded
second is employed to capture the miniature Side Impact Crash Demo Test kit, which enables the registrants to thoroughly analyze the crash impact. This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 12 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103. Learning Objectives By attending this seminar, you will be able to: • Explain frontal crashes and how vehicle structure and restraint systems affect occupant responses • Describe how restraint components function in crashes and protect occupants • Carry out calculations of injury metrics using test or CAE results as input • Describe the occupant CAE tool, Madymo, and how it works • Explain assumptions and limitations of CAE models • Evaluate the relative effect of crash pulse, and restraint system characteristics • Analyze and evaluate crash pulses • Describe FMVSS 208 and NCAP requirements and metrics • Explain the use of different dummies and their limitations Who Should Attend This course is designed for engineers who are either new to the field of automotive safety or familiar with only certain aspects of automotive safety. It can help engineers, for example, who design a specific component in a vehicle to understand how it works in vehicle crashes, how its characteristics affect occupant response and how it relates to other components in the vehicle. Prerequisites An undergraduate engineering degree or a strong technical background is highly recommended. Participants are expected to have a basic working knowledge of Microsoft Excel. • Vehicle Crash Safety Introduction −− U.S. crash injury and fatality data −− Distribution of different crash types −− Active and passive safety • Vehicle Frontal Crash Modes −− Frontal rigid, offset deformable and angular barriers −− Out of position tests, driver and passenger −− HYGE and Servo sled tests −− Component tests • Biomechanics - Human Anatomy and AIS Injury Scale • Brief Overview of Frontal Test Dummies and Injury Metrics Topical Outline DAY ONE
