| 中文摘要 | 空调内部的管道既是在运输和运行过程中最容易遭受破坏也是直接影响空调性能的必要组件。针对运输情形,本文首先利用ABAQUSE软件分析了管路的固有频率,进而通过增加管道约束的手段达到避免共振的目的。接着在压缩机出口处通过施加外部激励来模拟运行情形下的受迫振动情况,其位移结果与试验结果相符。通过进一步优化局部管道结构,成功降低了应力集中区的应力约15%。; In air conditioner,the pipes are not only the part that most probably damaged,but also the key part for well running. In this paper,the software Abaquse was used to study the vibrational status of the air conditioner. With modal analysis,the constraints of the pipes were improved to increase the intrinsic frequency that we can avoid resonating in transport.The external loading was applied on the endpoints of the pipes to simulate the effect of the compressor when operating. The results agree well with the experimental results. By optimizing the local pipe structure,the maximum Mises stress can be decreased by nearly 15%. |
