摘　　要：以商用车辆弹簧制动气室为研究对象,通过对其工作原理进行分析,利用Solid Works软件绘制出弹簧制动气室的三维结构实物图。基于该制动气室的数学模型,在多领域系统仿真分析软件AMESim中运用PCD气压元件设计库、气压库及机械库元件搭建详细的仿真模型。对各组分的参数进行设定,仿真得出弹簧制动气室在不同气源压力下动态响应及推杆行程变化曲线。仿真结果表明,仿真曲线符合工程实际要求,从而证明所建AMESim模型的正确性,也为车辆制动系统的进一步改进提供一定理论依据。Selecting spring brake chamber of commercial vehicles as the research object, SolidWorks are used for the rendering three-dimensional structure of spring brake chamber by analyzing the structure and working principle of its spring brake chamber. A detailed simulation sketch model is built using the PCD pneumatic component de- sign library, pneumatic library, mechanical library of multi-domain system simulation software-AMESim based on the mathematical model of the spring brake chamber. Set the simulation parameters of the sub models, the dynam- ic response curve and push rod stroke curve are acquired in simulation models under different conditions of air pressure. The simulation indicates that the simulation model is considered to be correct and meets actual require- ments. The result can provide a basis of further improve the barking system.
