Pred začetkom trženja izdelka je potrebno poznati njegovo obnašanje tekom celotnega življenjskega cikla. V ta namen se izvede množica testov, s katerimi zajamemo širok spekter obremenitvenih in okoljskih scenarijev. Na njihovi podlagi se določi zanesljivost izdelka. Delo obravnava proces utrujanja kolesnega elektromotorja, kjer so obremenitve določene na podlagi mednarodnega standarda SAE - J328/2016-3. Obravnavan je mehanski odziv njegove konstrukcije na zaporedje različnih obremenitev. Za združitev preučevanj utrujanja in mehanskega odziva, je bil razvit namenski testni postopek. Rezultati so podani v dveh delih. Prvi del predstavlja rezultat utrujanja, kjer konstrukcijo vrednotimo na podlagi razlik pomikov v zračni reži pred in po testiranju. Drugi del prikazuje velikosti pomikov v zračni reži v odvisnosti od aplicirane obremenitve. When marketing a product, it is essential to know its behaviour during the entire life cycle. For this purpose, a series of tests that cover a large spectrum of load and environmental stress scenarios are performed. Testing in such scenarios helps us to determine the reliability of the product during operation. The thesis considers the fatigue of an in-wheel motor, for which the loads are defined according to the international standard SAE - J328/2016-3. A new testing procedure was developed in order to combine the research of fatigue and mechanical response of the construction to a series of different loads. The results are separated into two parts. The first part represents the result of the fatigue testing, where the construction is evaluated according to the movements in the air gap before and after the test, while the second part shows the values of movements in the air gap and their dependence on the applied load. |
