SIMPLIFIED MODELS OF PNEUMATIC LONG LINE
Peszyński K.
pages 180 - +13p., full text

Pneumatic long line is a research object with complex parameters, described by a partial differential equation. Complexity of problems connected with an analysis of this type of objects leads to seeking different approximate ways of analyses. A partial differential equation can also be approximated by: system of difference equations, system of ordinary differential equations, and ordinary differential equation. This last procedure must be used of carefully, because we knowingly accept inaccuracy of the obtained model. Inaccuracy evaluation criterion of the simplified model is experimental comparison of responses obtained during the object testing with its model for a given case.
