Ultrasonic motors, used in cameras and other applications, present unique modelling challenges. The phenomena created in which ultrasonic waves with high frequencies are produced are difficult to capture in a model. The model must be accurate and execute quickly to be useful for controller design. Current modeling techniques have drawbacks. However, the use of a Reduced Order Model created by Model Order Reduction of a Finite Element Model has shown great benefits. With help from Maple’s advanced calculation capabilities:
the complex modeling challenges were alleviated
an accurate model of a USM was created
the model was created within a fraction of the time previously required with other modeling techniques
Poll: Should the UK’s railways be renationalised?
The term innovation is bandied about in relation to rail almost as a mantra. Everything has to be innovative. There is precious little evidence of...
