SECOND IN THE COMMERCIAL VEHICLE CRASH INVESTIGATION SERIES
Designed to further enhance the knowledge and skills you acquired in IPTM’s Commercial Vehicle Crash Investigation–Level I course, this class focuses on a detailed analysis of commercial vehicle systems and dynamics along with the application of your findings to the crash reconstruction.
We will begin by analyzing the ABS air brake system on commercial motor vehicle (CMV) truck-tractors and trailers by conducting tests to determine average air brake chamber pressure. You will participate in a “hands-on” field inspection as we conduct brake tests with a CMV.
We’ll teach you how to construct free-body diagrams and formulate equilibrium equations to determine the range of weight distribution on the axles. We will also examine quasi-static and dynamic rollover propensities and conduct an analysis of suspension spring rates.
After a review of high and low speed off-tracking, we will show you how to derive the equations for establishing maximum off-track distance. You will also learn how to interpret and analyze rotational motion that may be present in a CMV crash.
Finally, we will discuss the different types of transmissions used in today’s commercial motor vehicles and teach you how to obtain the range of speeds for the vehicle based upon the gear position at the time of the crash.
