摘　　要：在理论分析的基础上选择了数学模型,基于MATLAB/SIMULINK建立了仿真模型,并利用DZ270双缸柴油转子发动机的实验数据进行校准,通过仿真计算比较,三种工况下缸内压力的预测值和试验值的平均误差均在2%以内,满足工程应用要求;本模型易用于其它机型的仿真。A mathematics model is chosen based on theoretic analysis, and a simulation model is created by using MATLAB/SIMULINK. The simulation model is adjusted by experimentation data of DZ270 diesel dual-cyhnder rotary combusfon engihe. The simulation calculation shows that compare the mean error of pressure in cylinder in the three different work conditions can be limited in 2%. It can be easily apphed on other similar type of rotary combustion engine as well.
