HPM II H-Point Machine SAE Product Code: EA-3.01 The H-point is used as a key reference point in seated occupant location, seating package configurations, EPA volumes and crash test positioning. The HPM II H-point machine provides the physical representation of this reference point and is a vital element for design, auditing and benchmarking of seating and interior packages. The HPM II machine is used in conjunction with J 4002 rev. Jan. 2010, which includes many design changes and enhancements over the OSCAR H-Point machine. This new design includes; reformed shells for a consistent and reliable fit in bucket seats, articulating back for lumber support measurement, ability to measure H-point without use of leg and better design for ease of installation. Since the HPM II is not yet reference in the FMVSS or ISO standards it is primarily used in advance design applications. SAE provides comprehensive support for the HPM II machine including, calibration, spare parts and maintenance.

Fundamentals of Crash Sensing in Automotive Air Bag Systems provides a sound introduction for engineers designing air bag systems, accident reconstructionists, litigation professionals, managers, government employees, and anyone involved with automotive safety. Drawing upon the wisdom of many pioneers in the field, Chan presents a clear explanation of automotive air bag sensors using easy-to-read charts, tables, and figures. The book also includes a glossary of terms, and exercises for further study.

Collisions with young pedestrians often have serious traumatic and financial consequences. Allegations of negligence are frequently made against the drivers of involved vehicles, on the basis that they failed to take evasive action. A key element in determining the time available to the driver to avoid a collision is the speed of the pedestrian. In some instances, the young pedestrian is initially stationary in full view of the driver and then runs into the path of the vehicle. When this occurs, the acceleration of the pedestrian is an important element in determining the available time. This paper reports on accelerations from a standing start and associated walking, jogging and running speeds of pedestrians 5 – 17 years of age. Because children can vary considerably in height and weight for a given age, the effects of height and weight on acceleration and speed are also reported.

The time/distance relationship for a heavy truck starting from a stopped position is often needed to accurately assess the events leading up to a collision. A series of tests were conducted to document the low speed acceleration performance of a Freightliner FLD-120 tractor-truck. The tests including several load configurations and acceleration rates. The vehicle was instrumented with a DATRON speed sensor and the engine RPM was also documented. This paper presents data from these tests and discusses low speed acceleration profiles of heavy trucks

A simple two-dimensional particle model was previously developed to calculate occupant ejection trajectories in rollover crashes. Model parameters were optimized using data from a dolly rollover test of a 1998 Ford Expedition in which five unbelted anthropomorphic test devices (ATDs) were completely ejected. In the present study, the model was further validated against a dolly rollover test of a 2004 Volvo XC90 in which three unbelted ATDs were completely ejected. The findings from the experimental testing were then compared to two real world rollover crashes with occupant ejections that were captured on video. The crashes were reconstructed by analyzing the video footage and aerial images of the crash sites. In both cases, the model was able to accurately match the observed trajectories of the ejected occupants, and the optimized model parameters were similar to the values obtained from the dolly rollover testing.

A simple two-dimensional particle model was developed to predict the airborne trajectory, landing point, tumbling distance, and rest position of an occupant ejected in a rollover crash. The ejected occupant was modeled as a projectile that was launched tangentially at a given radius from the center of gravity of the vehicle. The landing and tumbling phases of the ejection were modeled assuming a constant coefficient of friction between the occupant and the ground. Model parameters were optimized based on a dolly rollover test of a 1998 Ford Expedition in which five unbelted anthropomorphic test devices (ATDs) were completely ejected. A generalized vehicle dynamics model was also created assuming a constant translational deceleration and a prescribed roll rate function. Predictions using the generalized model were validated against the results of the full-scale rollover test to estimate the expected error when using the model in a real world situation.
