摘要
曲轴是活塞式压缩机的关键零部件之一,对压缩机曲轴的疲劳强度进行准确的分析可以极大地提高压缩机的运行可靠性。以ZW-0.8/10-16风冷立式双缸单作用液化石油气压缩机为例,首先利用Solidworks软件建立了曲轴的三维模型,接着通过对压缩机曲轴的有限元分析,得到了曲轴疲劳破坏的危险点。最后利用ANSYS软件建立优化模型并对优化后的曲轴强度进行了验证。结果表明,有限元法可以较准确地对曲轴进行疲劳分析,进而对曲轴的设计和改进提供理论依据。
The crankshaft is one of the key parts of piston compressor; accurate analysis of fatigue strength in compressor crankshaft greatly improves operation reliability of compressor. Taking ZW -0. 8/10 - 16 air - cooled vertical two- cylinder single -acting liquefied petroleum gas compressor as an example, the compressor crank- shaft finite element analysis was conducted on the basis of three - dimensional model of the crankshaft established with the Solidworks software, and the risk point of fatigue failure of the crankshaft was obtained. The optimization model was established by ANSYS software to verify the optimized crankshaft strength. The results showed that the crankshaft fatigue analysis is more accurate with the finite element method, which provides a theoretical basis for design and improvement of the crankshaft .
