中文摘要：

针对碟螺离心机这种具有3个转子、两个转速、多种连接方式和支承形式的复杂转子系统,采用ANSYS参数化设计语言APDL编程进行参数化建模和动力特性仿真计算。建立有限元模型时用AN-SYS11.0新推出的Combin214单元耦合多个同心转子,该法方便可靠。

英文摘要：

APDL program was used to carry out the parameter model building and simulation calculation of power characteristics for a complex rotor system disc decanter, which has three rotors, two rotary speeds, many contact joints, and supports. Many concentric rotors were coupled by Combin214 unit that was newly derived from ANSYS11.0 when founding the finite element. The method is easy and reliable.
