摘要
为了提高旋转型行波超声电机定子端面质点的振幅值,设计了一种法兰状定子超声电机,并基于ANSYS软件建立了参数化有限元仿真模型,对其进行了动力学仿真分析。以定子端面振幅值最大为目标函数,基于Workbench对定子4个尺寸参数进行了优化设计,优化后的定子端面振幅值得到了很大的提高。此研究结果将提高法兰状定子超声电机的输出性能。
In order to improve the amplitude of the point on the end face of the rotating traveling wave ultrasonic motor stator,a flange-shaped stator ultrasonic motor is designed.The parametric finite element simulation model of the stator is established and the dynamics analysis is simulated using software ANSYS.When the maximum amplitude value on the stator end face is set as the objective function,the four geometric parameters of the stator are optimized using Workbench.As result the amplitude value on the optimized stator end face increases greatly which will improve the performance of flange-shaped ultrasonic motors.
