Abstract
A theory of order reduction is applied to the optimized finite element model of pipeline dynamics. Depending on the number of elements of the model, the order of the model can become very large. A technique to reduce the order of the finite element model is investigated while the reduced-order model still holds accuracy. Balanced realization and state elimination based on Hankel singular value are applied as the order reduction theory. As a result of order reduction, the number of order has been much decreased. The reduced-order model shows a good agreement with experimental results. Real-time simulation is possible by the reduced-order finite element model.
