摘要: 为有效预防汽车产品缺陷的产生,分析缺陷风险的变化过程,首先采用风险传递理论和系统动力学方法,利用汽车制动系统工作原理,分析缺陷风险的变化特征;其次综合考虑缺陷因素和人、机、环、管等影响因素与激发因素对风险的作用,分析从出现风险到导致事故和伤害过程的风险传递和演变机制,建立制动系统缺陷的风险传递动力学模型;最后利用仿真软件验证该模型。仿真结果表明:零部件缺陷风险在制动系统中按一定方向传递和演变;在影响因素和激发因素的催化作用下,风险按能量逐渐增大的方向传递;应根据风险传递特点,在传递过程中采取措施,阻断风险的正常传递。

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.

Key words: automotive brake system, defects in parts and components, risk transmission, system dynamics, analogue simulation
