Design of fatigue testing equipment (English)
This report comprises a construction of an fatigue testing equipment for a certain component at Komatsu Forest in Umeå. Testing components fatigue limit can act as compliment to the theoretical calculations. Fatigue testing equipment facilitates redesign by components because it gives fast response on whether changes was good or bad.The component this report deals with is a shaft mounted in a c144 harvester head. The axle is analysed regarding cracks, failure and through calculations with finite element method. The analysis indicates that the axle is exposed to bending forces that ultimately leads to its failure. The analysis and practical restrictions becomes the base for the design of the equipment. The equipment is designed to re-create the axles fatigue breaking through bending. Different designs regarding the equipment is discussed and also their advantages and disadvantages.The report result in complete manufacturing documents with drawings for all components and exploded views of the equipment. How the fatigue tests are done, measured, monitored and evaluated is also included in the report.
