Research on Optimal Design of Drive Mechanism in Stirling Engine

提出了热气机工质的一种循环压力改进计算方法,以理论输出功最大为目标建立了一种传动机构即Ericsson机构的尺度综合优化模型,确定了该机构的最佳几何参数。优化结果表明该方法对于优化该机构的几何参数、提高热气机的理论输出功率具有明显的效果。

A new calculation method for cycle pressure of the work media in Stirling Engine （SE） is proposed. The optimal model for the dimensional synthesis of the drive mechanism （DM） is established in order to maximize the theoretical output power. The optimal parameters of DM-Ericsson mechanism in SE are obtained by optimal method. The results of the optimization indicate that this method has the apparent effect upon optimizing geometric parameters and improving the theoretical output power of Stirling engine.
