Modelling of behaviour of spiral weld of high-pressure gas pipelines
Jíra, J. ; Jírová, Jitka ; Micka, Michal
The local effect of notches in the form of long cuttingson the development of deformations in the wall of a spiralwelded pipeline were modelled in the course of the hydraulicstrength test of hp gas pipelines. The influence of notchesand the spiral weld on the pipe state of stress wereinvestigated experimentally together with the numericalsimulation of the behaviour of pipes with defects bymeans of the application of the ANSYS programme.
Nd:YAG pulsed laser cutting of metals
Chmelíčková, Hana ; Polák, Marek
Pulsed Nd:YAG laser KLS 246-102 with average power 150W was developed for cutting, drilling and welding of metal and non-metal materials with thickness up to 2 mm. We chose an usually used kind of metal, steel (class 11) to test the optimal cutting conditions on various thickness from 0.1 to 1 mm.
Application of moiré topography for inspection of shape of pump blades
Rössler, Tomáš ; Hrabovský, Miroslav ; Keprt, Jiří ; Bartoněk, L.
The measurement of shape - the topography - of pump blade with the help of projection moiré is described here. The article contains theoretical basics of projection moiré the description of used experimental set-up and several representative experimental results.
Algorithm for automatic manufacturing control of general hydraulic surface
Rössler, Tomáš ; Hrabovský, Miroslav
During the manufacturing control the results of measurement of a surface have to be compared with a model (reference surface) given by the technical drawing to obtain the inaccuracy of manufacturing. Surfaces are generally rotated nad translated each to other.
