摘要
曲轴是往复压缩机的主要部件,压缩机运行过程中曲轴承受复杂的交变载荷的作用,易产生扭转振动,所以对6列曲轴必须进行扭振分析。基于往复压缩机向大功率、高速化发展的趋势,使用Pro/E建立不同结构的曲轴轴系模型,运用ANSYS对不同结构曲轴轴系进行静力和动力学分析,通过对比得出曲轴结构的变化对扭转振动的影响趋势,为高转速曲轴的设计提供理论上的支持。
Crankshaft is the main part of the reciprocating air compressor, and the crankshaft is easy to produce torsional vibration, since it is subjected to complex alternating load in the process of operation. Therefore, torsional vibration analysis must be carried out on the six columns of the crankshaft. To high-power, high-speed development trend, the crankshaft system models with different structure are established using Pro/E, and using ANSYS for static and dynamic analysis of the crankshaft. The influence of the change of the crankshaft structure on the torsional vibration can be obtained by the comparison of the results. It also can provide theoretical support for the design of high speed crankshaft.
