The low-cost and easy-to-operate method for measuring the dynamic collapse velocity of steering column is realized, and the problem that the dynamic collapse displacement of steering column can not be measured in the vehicle crash test is solved. In other words, an acceleration sensor is installed on the upper and lower cylinder of the steering column to measure the collapse acceleration of the steering column when the dummy impacts the steering system. By modifying the measured acceleration and integrating the acceleration, the collapse velocity and the collapse time of steering column are obtained. Finally, the measurement results are validated by the sled test and high-speed video analysis. It is confirmed that this method can be used to measure the collapse parameters of steering column in the vehicle collision test.
