摘要: The objective of this research task is to implement a model make it possible simulate the fatigue behavior helicopter blade by modal analysis. A study aerodynamics helicopters was made though determination loads applied main and extract their frequencies eigen modes with crack without crack. expressions different energies virtual work from elements are developed. finite element defined in order vibratory phenomena. This makes Eigen shapes blade, calculate stresses which act on structure.
