p.535 Prediction of the Fatigue Life for Large Wind Turbine Gearbox. p.539 Artificial Immune Systems Applied to the Analysis of Structural Integrity of a Building. HomeApplied Mechanics and MaterialsApplied Mechanics and Materials Vol. 472Prediction of the Fatigue Life for Large Wind... Wind turbine gearbox is the key component. In this paper, obtaining the stress time histories through multi-body dynamics simulation, then base on the simulation data, statistical processing load time histories by used rain flow counting method, the last is that estimating fatigue life of components, combined with P-S-N curves of parts material and linear cumulative damage law. The fatigue life prediction of each component in gearbox would be implemented by matlab programming. Through the fatigue analysis of a megawatt-class wind turbine gearbox transmission chain, the design was verified feasibility, but not economic, and it show that this method has certain reference value and potential for improvement.

World leading FEA and CFD Simulation Services Engineering Company for CFD and FEA and Engineering Simulation. # Fatigue Analysis: Stress-Life Method for Wind Turbines. | What you will learn in this article In this blog post, you can discover the origins of engineering fatigue assessment and learn, based on a real simulation problem, how to apply S–N curves to assess high-cycle fatigue. The results of his investigations are still illustrated today by the S-N Curve (also known as the Wöhler Curve), one of the fundamental tools used to assess fatigue in engineering. In this use case, we demonstrate this concept by simulating the fatigue behavior of an aluminum wind turbine blade, illustrating why such a design would not be practical. It describes the relationship between the stress amplitude S and the number of cycles to failure N for a specific material.
