Rollover Testing Methods

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J2926_201707
  • Current
Published 2017-07-28 by SAE International in United States
The scope of this document is to provide an overview of the techniques found in the published literature for rollover testing and rollover crashworthiness evaluation at the vehicle and component levels. It is not a comprehensive literature review, but rather illustrates the techniques that are in use or have been used to evaluate rollover crashworthiness-related issues.

Linear Impactor Calibration Procedure

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J3095_201606
  • Current
Published 2016-06-17 by SAE International in United States
This recommended practice provides a procedure for measuring quantitatively the physical characteristics of linear impactors that are believed to effect impact test accuracy, repeatability, and reproducibility. Suggested values and tolerance are also provided for specific applications of linear impactor testing (i.e. Ejection Mitigation tests, Head form Impact tests, Body Block tests). Two functional groups of linear impactors are considered, those whose function is related primarily to displacement and those related to measuring acceleration or force.

Linear Impact Procedure for Occupant Ejection Protection

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J2937_201604
  • Current
Published 2016-04-28 by SAE International in United States
The objective of this document is to enhance the test procedure that is used for ejection mitigation testing per the NHTSA guidelines as mentioned in the FMVSS226 Final Rule document (NHTSA Docket No. NHTSA-2011-0004). The countermeasure for occupant ejection testing is to be tested with an 18kg mass on a guided linear impactor using the featureless headform specifically designed for ejection mitigation testing. SAE does not endorse any particular countermeasure for ejection mitigation testing. However, the document reflects guidelines that should be followed to maintain consistency in the test results. Examples of currently used countermeasures include the Inflatable Curtain airbags and Laminated Glass. The testing procedure is as follows: 1 Determine the daylight opening 2 Identify target locations per the FMVSS226 Final Rule §5.2 a Target locations for all windows and daylight openings b Perform the target elimination process c Reconstitute the targets 3 Determine the zero-plane 4 In case of advanced glazing, determine if the glazing has to be part of the test and pre-brake it at a 75mm offset a If yes, than…

Electric Vehicle (E-Vehicle) Crash Test Lab Safety Guidelines

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J3040_201512
  • Current
Published 2015-12-17 by SAE International in United States
The special risks associated with conducting crash tests on E-Vehicles can be divided into two main categories; 1) thermal activity inside the battery (resulting from electrical or mechanical abuse) may lead to energetic emission of harmful and/or flammable gases, thermal runaway, and potentially fire, and 2) the risk of electrocution. Procedures to ensure protection from all types of risk must be integrated into the entire crash test process. This informational report is intended to provide guidance in this endeavor using current best practices at the time of this publication. As both battery technology and battery management system technology is in a phase of expansion, the contents of this report must then be gaged against current technology of the time, and updated periodically to retain its applicability and usefulness. The scope of this document is to provide an understanding of the risks and an overview of the techniques established to reduce the likelihood that an event would cause harm to laboratory personnel and/or property. A laboratory considering E-Vehicle crash testing should work closely with the E-Vehicle…

Fixed Rigid Barrier Collision Tests

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J850_201504
  • Current
Published 2015-04-09 by SAE International in United States
Fixed rigid barrier collisions can represent severe automotive impacts. Barrier collision tests are conducted on automotive vehicles to obtain information of value in reducing occupant injuries and in evaluating structural integrity. The purpose of this SAE Recommended Practice is to establish sufficient standardization of barrier collision methods so that results of similar tests conducted at different facilities can be compared. The barrier device may be of almost any configuration, such as flat, round, offset, etc.

Moving Rigid Barrier Collision Tests

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J972_201503
  • Current
Published 2015-03-13 by SAE International in United States
Collision tests are conducted on automotive vehicles to obtain information of value in evaluation of structural integrity and in reducing the risk of occupant injuries. The deformation resulting from a moving rigid barrier impact is more severe at a given speed than that produced by using an actual vehicle, but is more readily reproducible than that occurring during vehicle to vehicle impacts. The purpose of this SAE Recommended Practice is to establish sufficient standardization of such moving barriers and moving barrier collision methods so that results of tests conducted at different facilities may be compared.

Vehicle Roof Strength Test Procedure

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J374_201503
  • Current
Published 2015-03-13 by SAE International in United States
This SAE Recommended Practice establishes a uniform laboratory test method to evaluate the strength characteristics of roof systems. The test procedure is intended to provide reliable and repeatable results and to permit numerical comparisons. A test is conducted in which the vehicle roof system is loaded under controlled laboratory conditions. Structural strength measurements are obtained under load application angles chosen to concentrate forces on the forward portions of the roof panel and roof supporting structure.

Dynamic Simulation Sled Testing

Impact and Rollover Test Proced Stds Comm
  • Ground Vehicle Standard
  • J2481_201310
  • Current
Published 2013-10-29 by SAE International in United States
Dynamic simulation sled testing can represent various automotive collision conditions. Acceleration conditions during sled testing are readily reproducible and can be tuned to simulate collision events that occur during vehicle impacts with a fixed barrier or vehicle. Sled tests are conducted on automotive vehicle bodies or other structures to obtain valuable information. This information can be used to evaluate the dynamic performance of, but not limited to, vehicle restraint systems, vehicle seating systems, and body closure systems.

  • Current
Published 2011-02-21 by SAE International in United States
This SAE Recommended Practice describes the test procedure for conducting a rollover test using a dolly fixture designed to laterally trip a vehicle into a roll. Its purpose is to establish a recommended test procedure which will standardize the procedure between different test facilities. A description of the test procedure, test instrumentation, photographic/video coverage, and the rollover fixture is included.
