| 中文摘要: |
| 曲柄连杆机构的运动学和动力学性能对压缩机工作目标参数具有重要影响。提出基于Solidworks和Adams构建曲柄连杆机构的运动学和动力学耐久性分析模型，预测机构的疲劳寿命，即压缩机连续工作205 d后，机构振动频率逐渐增大；连续工作240 d时，振动频率达到最大，压缩机将失去工作能力。然后通过理论模型与物理模型的疲劳耐久性双重验证，表明其吻合较好，从而为压缩机曲柄连杆机构的优化和创新设计提供参考。 |

| The kinematics and dynamics performance of the crank connecting rod mechanism have important influence on the target parameters of the compressor. Based on Solidworks and Adamas, a kinematic and kinetic durability analysis model of crank connecting rod mechanism is proposed to predict the fatigue life of the mechanism. That is, when the compressor is continuously operating 205 d, the vibration frequency increases gradually. After continuous operation 240 d, the vibration frequency reaches the maximum, and the compressor will lose its working ability. Then, the fatigue durability of the theoretical model and the physical model is verified by double tests, which shows that they are in good agreement. So as to provide reference for the optimization and innovative design of compressor crank connecting rod mechanism. |
