Training / Education Classroom Seminars
Car companies and suppliers continue to develop new technologies that make vehicles safer and regulatory agencies continue to update safety regulations based on new research studies, making vehicle safety design more and more complex. This seminar covers the mechanics of frontal crashes and how vehicle structures, vehicle restraint systems, and vehicle interiors affect occupant safety. It also describes details of how CAE tools work in the simulation of frontal crashes. The goal of the course is to familiarize participants with engineering principles behind vehicle and restraint designs for occupant safety.

Every year, the U.S. experiences more than 32,000 traffic deaths and over 3.8 million crash injuries. While the trend in traffic deaths has been downward for the past decade, most of this reduction has been the result of optimizing passive occupant crash protection systems such as seatbelts and airbags. Advanced driver assistance systems (ADAS) now offer the potential to significantly reduce or eliminate most vehicle crashes by perceiving a dangerous situation before the crash has occurred and taking action to avoid or mitigate the crash.

Motivation – Achieving functional safety in mechatronic systems with growing product functionality is a major challenge in systems engineering. Following the current discussion, this challenge is mostly allocated to electronics and software development. For most of the scenarios this focus is feasible. Product design – the construction of the product – defines the properties and the appearance of the product by shape, material and assembly. So, the product design is often not under control of the safety management system. A hazardous deviation of part shape can be easily identified after the parts product or at least at its mounting. A wrong assembly is controlled by assembly documentation or data (e.g. screw torques) and identified at end of assembly line checks. The identification of a hazardous material choice depend on the product material class. Product materials can be separated into two classes: passive or active materials.

In this paper, the capability of three methods of modelling detonation of high explosives (HE) buried in soil viz., (1) coupled discrete element & particle gas methods (DEM-PGM) (2) Structured - Arbitrary Lagrangian-Eulerian (S-ALE), and (3) Arbitrary Lagrangian-Eulerian (ALE),are investigated. The ALE method of modeling the effects of buried charges in soil is well known and widely used in blast simulations today Due to high computational costs, inconsistent robustness and long run times, alternate modeling methods such as Smoothed Particle Hydrodynamics (SPH) and DEM are gaining more traction. In all these methods, accuracy of the analysis relies not only on the fidelity of the soil and high explosive models but also on the robustness of fluid-structure interaction. These high-fidelity models are also useful in generating fast running models (FRM) useful for rapid generation of blast simulation results of acceptable accuracy.

In motor-vehicle frontal crashes, occupants often suffer from the abdominal injuries when the lap belt excurses over the pelvic bone, commonly referred to as submarining. Especially, it is well known that the obese occupants frequently get injured caused by submarining due to out-of-position belt fittings. This paper aims to investigate the interaction between the pelvis and the lap belt during a frontal crash event. For this purpose, twelve sled tests on four obese female Post-Mortem Human Subjects (PMHS) and four sled tests on the Hybrid III 50th dummy were carried out. In each test, a 3D motion capture system was installed to track the movement of the pelvis and the lap belt. Moreover, the validated subject specific FE model scaled from the 50th percentile male GHBMC model to fit to obese female PMHS in prior study was also simulated.

When the steer axle of a vehicle with protruding wheel studs makes contact with another vehicle or object in a sideswipe configuration, the tires and wheel studs of the vehicle can deposit distinct geometrical patterns onto the surfaces it contacts. Prior research has demonstrated how relative speeds between the two vehicles and surfaces can be calculated through analysis of the distinct patterns. This paper presents a methodology for performing this analysis by visually modeling the interaction between wheel studs and various surfaces, and presents a method for automating the calculations of relative speed between vehicles. This methodology also augments prior research by demonstrating how the visual modeling and simulation of the wheel stud contact can extend to almost any surface interaction that may not have any previous prior published tests, or test methods that would be difficult to setup in real life.

Out-of-position (OOP) driver tests were designed to address concerns about airbag introduced injury in situations while the occupant is nearer to the airbag module than in a normal seated position. The 5th percentile female has instrumentation for measuring ATD sternum displacement (potentiometer) and acceleration (accelerometers) which can be used to compute compression rate. This paper documents a study investigating the capability of the chest accelerometers to accurately assess non-distributed loading of the chest during this test configuration. The study included ATD mechanical loading and instrumentation review. Finite element analysis was conducted using a Hybrid 3 - 5th percentile female ATD correlated to testing. The correlated restraint model was utilized with a Hybrid 3 – 50th percentile male ATD. A 50th percentile male Global Human Body Model was then applied for enhanced anatomical review.
