High-end software for propulsion shaft calculation

  Yuriy A. Batrak PhD, Intellectual Maritime Technology Martin van Leest, Machine Support B.V. ABSTRACT There are three main problems for engineers specializing in propulsion train calculation. The first problem is a lack of a single shaft model to perform all types of shaft related calculations, the second is the inability to analyze different operation …

Computer application for shaft alignment design

Computer application for shaft alignment design

  Yu. Batrak, R. Batrak, D. Berin, Intellectual Maritime Technologies, UKRAINE SUMMARY The propulsion shafting operates at the junction of different media where the interacting conditions change constantly depending on the ship draught, engine speed, ambient and machinery temperature. Once installed on the flexible hull structures it is exposed to hydrodynamic propeller loads, variable contact …
