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
Engineering industry reacts to Reeves' budget
I´d have to say - ´help´ - in the longer term. It is well recognised that productivity in the UK lags well behind our major industrial competitors and...
