  • Dynamic Roof Crush Tests of Ten 2005-07Passenger Vehicles
    The purpose of this program was to alert the public to the dramatic difference in structural roof performance and rollover safety of the vehicles they buy; and to show the inadequacies in the recently amended roof crush resistance standard, FMVSS 216, issued by the National Highway Traffic Safety Administration (NHTSA)
  • Roof strength - IIHS-HLDI
    We evaluated roof strength because it is crucial for maintaining occupant survival space during a rollover Stronger roofs crush less, reducing the risk that people will be injured by contact with the roof itself
  • 32 rollover and roof crush investigation - autosafetyexpert. com
    tests of 150 to 200 vehicles each year While commendable, the key will be how rapidly and effectively the test knowledge is transferred into GM’s mass-produced vehicles with stronger roof structures, more effective side-curtain airbags, safer side-window glazing, more effective seatbelt restraint
  • ESV M216-JRS paper Final
    The study is ongoing with very preliminary results shown in Table 1, comparing the dynamic crush and crush speed results of 5 and 10 degree tests for two SUVs and a passenger car
  • Passenger Vehicle Roof Strength - Department of Transportation
    Subsequent to issuance of the NPRM, the agency conducted extensive testing of current production vehicles to, among other things, determine the effects of two-sided testing and to assess the roof strengths of vehicles currently on the market These test results were released in the SNPRM
  • Table of Contents Outline for FMVSS 216 NPRM - NHTSA
    Reports on these tests explain the procedure and type of fixture used to assess headroom reduction (As explained elsewhere in this document, these test reports are being made available to the public through the agency’s internet vehicle crash test database )
  • Innovative Roof Crush Test Proves You Can Buy Vehicles That Can Protect . . .
    – The Center for Auto Safety and Public Citizen today unveiled the innovative Jordan Rollover System (JRS), a superior test device for analyzing vehicle roof strength and rollover crash protection under real-world conditions, in a press conference at the George Washington University
  • (PDF) Quasi-Static and Dynamic Roof Crush Testing - Academia. edu
    Nine vehicles tested revealed differences in roof strength and performance; Dodge Colt ranked poorly by absolute strength but well by normalized energy Dynamic energy absorption slopes ranged from 1 1 to 1 6 times static slopes, necessitating careful correlation for FMVSS updates
  • Roof Crush - centerforinjuryresearch. org
    JRS Testing - Click on vehicle below for description and test
  • QUASI-STATIC AND DYNAMIC ROOF CRUSH TESTING - TRID
    A study was conducted at the Vehicle Research and Test Center to investigate roof crush resistance in passenger vehicles The objective was to determine the correlation between roof crush performance measured quasi-statically and dynamically
