Abstract

The changing process of defect risks are analyzed in order to effectively prevent defective automotive products. Firstly, the changing characteristics of defect risks were analyzed by using the risk transfer theory, system dynamics method and working principles of automobile brake system. Secondly, the risk transfer and evolution mechanism from risk occurrence to accident and injury process was analyzed and a risk transfer dynamics model of brake system defect was established with defect factors, influence factors like human, machine, ring and tube and the triggering factors being considered. Finally, the simulation software was used to verify the model. The simulation results show that the risk of component defects is transmitted and evolved in a certain direction in the brake system. Under the catalysis of influence factors and triggering factors, the risk is transmitted in the direction of increasing energy. Measures should be taken to block the normal transmission of risk according to its transmission characteristics. © 2019 China Safety Science Journal
