Analysis of Production Parameters of a Hydraulic Drive Designated to Work in Low Temperatures

When designing technical systems, one of the most important tasks is to determine their operating parameters in target conditions. Most often, these are model activities aimed at conducting tests on model systems or prototypes of the analyzed systems. Conducting such research also involves their proper analysis. This publication presents a solution proposed for such situations. The publication presents an example of testing a hydraulic system at low temperatures, as well as an analysis of test results and a determination of the scope of objectives based on the weighted Ishikawa diagram. The system was tested at −50 ℃ and problems were identified at this temperature. Operational problems at such a low temperature were then analyzed using a 10M fishbone diagram. The obtained results allow both to define further research procedures and to set further research directions. They also allow for the assessment of interactions between identified problems.
