Abstract

Side pole impact is a common form of road traffic accident. Due to the narrow side energy absorption space, the development of the vehicle side restraint system has put forward strict requirements. However, the reappearance accuracy of side pole impact sled in the industry is always at a low level, and enterprises can only choose expensive real vehicle tests or CAE methods for development. In this paper, a multi-cylinder intrusive side pole sled impact test method is proposed. Through the coupling and decoupling of the pulses between the main sled and the side impact sled, the interaction process between the door and the dummy in the real vehicle impact test is well simulated, and the V-type intrusion is realized. The data after the test is analyzed in detail. The chest ribs and abdominal ribs of the dummy show good consistency, and the deviation can be controlled within 15%, which greatly reduces the development cost of the side pole impact. At the same time, there are also deviations in the compression amount of the upper rib and the force of the pubic symphysis force, which can be continuously optimized in the follow-up work. This research provides a new idea and solution for the development of the side restraint system.
