摘　　要：为了减小整体旋转式斯特林制冷机运行过程中曲柄连杆机构产生的不平衡惯性力,建立了制冷机三维模型。对制冷机机构进行分析;运用CAE软件对制冷机工作时的运动进行动力学仿真。计算出制冷机运行过程中产生的不平衡力,通过设计优化平衡块的质量减小曲柄连杆运动过程中产生的不平衡惯性力,并为制冷机设计优化方法。An optimal 3D- model of integral rotary Stirling cryocooler was applied to study how to reduce the unbalanced inertia force which occured to the circumnutation of crank- connecting rod mechanism. The whole mechanism of cryocooler was studied and CAE software was introduced to simulate the dynamics motion process of the cooler operation. Since the value of the unbalance inertia force was calculated,the balance weight could be optimal to reduce the unbalanced inertia force. The proposed method was available for design and optimization of integral rotary Striling cryocooler.
