摘要
以ANSYS软件作为平台,用预应力法求解了转子的临界转速.对计算过程作了定性分析,推导了计算公式.对计算的结果和自编有限元程序得出的结果作了比较,精度较高.对于多跨转子与其每一单跨转子临界转速之间的关系,作了阐述.
The prestress method is used to calculate the critical frequencies of a rotor on ANSYS plate-form. The calculating process is analysed and the formula is obtained. The results are compared with those of the finite elements method. The relations between the critical frequencies of the multi-span ro-tor and those of its single-span rotor are explained.
