Side impact crashes account for approximately twenty-six percent of all motor vehicle fatal crashes, second only to frontal crashes, according to a report by the National Highway Transportation and Safety Administration (NHTSA). While car companies and suppliers continue to develop new technologies that make vehicles safer, NHTSA rolled out updated safety regulations (FMVSS 214) based on new research studies, making vehicle safety design more and more complex. This seminar is designed to familiarize participants with the engineering principles behind vehicle and restraint designs for occupant safety.

Note: Last day of class ends at approximately 1:00 pm According to the Federal Rules of Evidence, an expert witness is anyone who can assist the trier of fact (the jury) in understanding any issue in dispute at trial. The witness' ability to give this assistance can be derived from any specialized training, education, background, or experience. To be effective in providing this assistance, however, requires that the expert witness understand the true role that he or she is to play both before and at the trial.

One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena.

Automotive crash reconstruction is a process carried out with the specific purpose of estimating in both a qualitative and quantitative manner how a crash occurred. Reconstructions are based on data collected during the crash and physical evidence gathered during a crash investigation. To some extent, testimonial evidence is also used. Whether a crash is between two vehicles, a vehicle and pedestrian or a vehicle and a barrier, specific crash segments, classified as pre-impact, impact and post-impact motion often are reconstructed separately.

EDR’s are not new, but are becoming more prevalent in part due to a new federal regulation. 49 CFR, Part 563, which affects vehicles produced after September 30, 2012, will result in a standardized and publicly available EDR in 90% of new vehicles. Accident Reconstructionists frequently have trouble reconciling EDR data with other data sources, and improvements in ABS technology result in fewer tire marks visible at the scene of crashes to allow calculation of pre-crash speeds without an EDR.

Safety continues to be one of the most important factors in motor vehicle design, manufacture and marketing. This seminar provides a comprehensive overview of these critical automotive safety considerations: injury and anatomy; human tolerance and biomechanics; occupant protection; testing; and federal legislation. The knowledge shared at this seminar will enable attendees to be more aware of safety considerations and to better understand and interact with safety experts. This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 18 Continuing Education Units (CEUs).

Abstract Studies have shown that the number of road accidents caused by rollover both in Europe and in Turkey is increasing [1]. Therefore, rollover related accidents became the new target of the studies in the field of vehicle dynamics research aiming for both active and passive safety systems. This paper presents a method for optimizing the rear suspension geometry using design of experiment and multibody simulation in order to reduce the risk of rollover. One of the major differences of this study from previous work is that it includes statistical Taguchi method in order to increase the safety margin. Other difference of this study from literature is that it includes all design tools such as model validation, optimization and full vehicle handling and ride comfort tests. Rollover angle of the vehicle was selected as the cost function in the optimization algorithm that also contains roll stiffness and height of the roll center.

The field of vehicular accident reconstruction has become increasingly specialized. For automotive engineers involved in crash reconstruction and analysis, a knowledge of basic accident reconstruction principles and techniques is essential, but often insufficient to answer the sophisticated questions posed by design engineers, regulators, and lawyers. This seminar takes participants beyond the basics of accident reconstruction to physical models and analysis techniques that are unique to the reconstruction of single-vehicle rollover crashes.

Distinguished from the conventional internal combustion engine vehicles, most of the pure electric vehicles are equipped with only a fixed-ratio reduction gear, because of the wide speed range of the electric motor. For most of the vehicle’s speed and acceleration requirements, they can be satisfied through application of only a fixed-ratio reduction gear. However, within some speed range, the operation efficiency of the electric motor is relatively low, which affects the overall energy efficiency of the electric vehicle. Thus, application of a two-speed gearbox is able to remain the electric motor working within high-efficiency range during the whole operation conditions, which has a good potential to further improve the electric vehicle’s energy economy. Based on the above analysis, in this paper, gear ratios of a two-speed transmission system are optimized for an electric passenger car.

Occupant Kinematics in Distinct Types of Far-side Impacts Objective: Occupant contacts not on a trajectory not in line with a response to the resultant impact vector are seen as the consequence of post-impact vehicle rotation. This analysis evaluates field data for indications the trajectory occupant contacts indicate in far-side impacts is affected by the acceleration of the vehicle. Methods: Using the WinSMASH calculated moment arm a classification scheme was devised. WinSMASH calculates and reports moment arm length and sign. Moment arm length was used to classify impacts as ‘centric’ or ‘eccentric’ relative to the vehicle center of gravity. A query was made for far-side impacts in CIREN. 111 cases were reviewed and WinSMASH re-run. The results were used to classify impacts by the crush profile center-of-damage and principal direction of force. All AIS 2+ injuries were located on whole body and specific anatomic region mannequins.
