GB/T 14172-2009 stipulates the test method of the vehicle static rollover Stability bench. The standard specifies the details of the preparation of the test vehicle, including the vehicle state, load distribution, etc. The requirements of the bench test equipment are detailed, such as the specifications of the tilt device, the accuracy of the measuring instrument, etc. During the operation, the fixed mode of the vehicle on the bench, the rate of change of the tilt angle and the Measurement parameters are standardized. According to this standard test, the ability of the car to resist rollover under static conditions can be accurately evaluated. It provides a key basis for the research and development of automobile safety performance and mass testing, and helps car companies to improve product safety and ensure the safety of drivers and passengers.
