Conception and practical application of a measuring device for energetic parameters measurement of a mechatronic object

摘要

In the article, assumptions of the developed non-invasive method of evaluation the technical condition of selected structural elements of the ship's diesel-electric set at limited monitoring susceptibility, when the engine is not equipped with indicator valves, are discussed. The method is based on simultaneous measurements of phase-to-phase voltage of the synchronous generator, exhaust gas pressures in the exhaust manifold, and vibration accelerations of some parts of the set. To the purpose of the accomplishment all measurements of energetic parameters at the same time, it turned out to be necessary to design and construct the measured quantity converter. In the paper the requirements in relation to such a converter, the technical project, and the representative results of measurements conducted on a real object - diesel-electric set type ZE400/52 - are presented.
