The challenge

The US Army needed outside expertise in delivering a vertical impact test system which could simulate the vertical energy associated with IED explosions, originating from underneath a vehicle, in a controlled laboratory environment.

  • The US Army needed outside expertise in delivering a vertical impact test system which could simulate the vertical energy associated with IED explosions, originating from underneath a vehicle, in a controlled laboratory environment.

The solution

  • Lansmont designed the VITS (Vertical Impact Test System), called Crew Seating Blast Effects Simulator (CSBES) by the Army Research Lab.
  • Stationary table impacted by a 1,200 lb bullet fired by a pneumatic piston.
  • Enough energy to drive the table with a 650 anthromorphic dummy 7 meters per second.
  • Three programmed impacts per event:
    1. Initial impact to the feet area
    2. Main shock event to table
    3. Ensuing “after shock” coming from vehicle landing, know as “slam down“.
