Research on the biomechanics friction characteristics based on the typical bus

Abstract

The simulation precision of the vehicle–pedestrian accident is influenced by the numerous pre-impact parameters. Among them, the biomechanics friction characteristics of pedestrian exert direct influence on the reconstruction of vehicle–pedestrian accident. Given the complicacy of human body and the traffic accident, it is difficult to chase down the pedestrian–vehicle and pedestrian–road contact characteristics in the accident merely through experiments. The analysis on biomechanics friction characteristics in vehicle–pedestrian accident based on the design of experiment method are discussed in this article. The reliability of the friction characteristics can be verified by the optimization method. Finally, the method is applied to reconstruct a real typical case of a bus–pedestrian accident. The numerical reconstruction results gained by the method have high accuracy and credibility. The study also provides a new way to analyse the vehicle–pedestrian accident cause.
