Commercial Vehicle Crash Investigation - Level II  

SECOND IN THE COMMERCIAL VEHICLE CRASH INVESTIGATION SERIES

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.

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.

Topics Include

  • Tractor-trailer ABS air brake system
  • Hydraulic brake systems in commercial vehicles and how fluid pressures are boosted
  • Quasi-static and dynamic rollover propensities and liquid loads
  • Axle weight analysis and load reconstruction
  • Trailer coupling devices - fifth wheels
  • Off-tracking
  • Speed from gear ratio
  • Rotational mechanics
  • Skid mark measurements and speed analysis
  • Field inspection

Audience

Law enforcement and private traffic crash investigators, claims adjusters, engineers, attorneys, safety officers, military investigative personnel, animators and graphic designers
