Tiivistelmä
Fatigue testing is a crucial aspect in the process of the engineering design. To acquire the information on the fatigue strength and life, testing equipment have been developed. With the help of such devices, the data on the component or material in-service behaviour is gathered.
For the past years, student of HAMK Riihimäki were developing the fatigue testing unit in the laboratory of Automation engineering. The principle of the machine is based on the servo-hydraulic components operated by the programmable logic controller.
The thesis contains the information on commissioning this fatigue testing unit and process of its development. The work has started in February 2017 and has lasted until the end of May. Primary modifications had been done on the gripping mechanisms, servo-hydraulic and direction control hydraulic valves, PLC unit and its programming.
As the result of the thesis, the testing unit was commissioned and was capable of doing high-cycle axial fatigue tests of thin plate parts. The thesis also provides the information on the possible future system modifications in order to collect test data.
