八缸制冷压缩机的最佳气缸排列

The Optimum Cylinder Arrangment for Eight Cylinders Refrigeration Compressor………

本文以曲轴在危险工况下最危险截面上的复合应力和疲劳安全系数为目标函数,通过强度计算和分析对八缸制冷压缩机的气缸排列进行优化,确定了在皮带传动和直联两种情况下气缸排列的最佳方案,从而提高了制冷压缩机的可靠性和耐久性。

This paper chose complex stress and fatigue safety factor on the most dangerous section of crank shaft as aim function under dangerous condition. By strength calculation and analysis of the optimum cylinder arrangement for eight cylinders refrigeration compressor, the optimum option was determined in the both case of belt driven and direct driven. Therefore the riliability and durability of refrigeration
