摘　　要：本文介绍了储能技术的应用以及空气储能技术的原理,并以盐穴空气储能透平机组轴系为研究对象,首先对轴系转子进行了模化,然后采用有限元方法计算了轴系的横向弯曲无阻尼临界转速、不平衡量响应和轴系的稳定性情况;同时采用连续质量的传递矩阵法计算了轴系的扭振固有频率,计算结果表面透平机组能满足安全运行要求。This paper introduces the application of energy storage technology and the principle of air energy storage technology, and takes the shafting of salt cavern air energy storage turbine unit as the research object.Firstly,the shafting rotor is modeled,and then the finite element method is used to calculate the undamped critical speed,unbalance response and stability of the shafting in transverse bending.The natural frequencies of torsional vibration of the shafting system are calculated by using the transfer matrix method of continuous mass.The calculated results show that the surface turbine unit can meet the requirements of safe operation.
