摘　　要：以某大型4列往复压缩机曲轴系为研究对象,用Ansys有限元建模的方式,对曲轴进行模态分析和谐响应分析。分析发现原曲轴系存在扭转振动隐患,通过调整设计参数,改善了曲轴系扭振状况,改进了曲轴动力学特性。Aiming at the crankshafts of a large-scale 4-column reciprocating compressor, the modal analysis and transient responseanalysis on the crankshaft were analyzed by Ansys finite element modeling. The hidden trouble of torsional vibration on the originalcrankshaft system was discovered. By adjusting the design parameters, the torsional vibration condition of crankshaft system was im-proved, and the dynamic characteristics of crankshaft were optimized.
