为研究可变容积气室在AMESim气动模型中的应用，在分析引入可变容积气室的建模方法的机理的基础上，建立了CCB II制动机电空控制单元中均衡风缸控制模块的两个气动模型。通过仿真对比分析引入可变容积气室后均衡风缸内气体压力、三通阀阀芯位移、可变容积气室体积的变化。仿真结果表明引入可变容积气室来反映阀内腔体等气体容积变化的实际情况，使建立的仿真模型更加科学，而引入可变容积气室的建模方法是可行的。

In order to study the application of variable volume pneumatic chamber in AMESim pneumatic model, two models of Equalizing Reservoir Control Portion, which are one of the pneumatic components of Electro-Pneumatic Control Unit of CCB II brake control system, are established based on the analysis of the mechanism of modeling method of applying variable volume pneumatic chamber. Through simu-lation of the two models, the air pressure in equalizing reservoir, the displacement of valve core in triple valve and the change of variable vol-ume pneumatic chamber's volume can be compared. The results show that by the application of variable volume pneumatic chamber, the ac-tual situation of pneumatic volume's change of the valve cavity can be correctly reflect, and the model built more scientific. Thus, the model-ing method of applying variable volume pneumatic chamber is feasible.
