为了保障多轮盘转子系统的稳定性,针对多轮盘转子临界转速的确定问题,分别采用了邓柯莱法,传递矩阵法和基于ANSYS的有限元法进行求解,并对所得结果进行了分析和比较。结果表明三种方法的适用范围不同,其中基于ANSYS的限元法对转子系统的临界转速的求解准确度高,计算简便,为工程上其它转子系统的临界转速的求解提供了可靠的依据。
In order to ensure the stability of the many roulette rotor system,for the determination of the rotor system critical speed, DengKe lai method was adopted, and using matrix method and the finite el- ement method to calculate based on ANSYS respectively for the critical speed,and the results were com- pared and analyzed.The results show that the three methods are of different range ,in which the limited ele- ment method based on ANSYS/s in high accuracy,with simple calculation,providing for other engineering of the rotor system solution of the critical speed a reliable basis.
