- W2068124520 abstract "The optimum design of rotating laminated blade subject to dynamic behavior constraint is investigated. The dynamic behavior constraints consist of restrictions on multiple natural frequencies as well as on maximum dynamic deflections of rotating laminated blade. The harmonic excitations are considered to simulate the aerodynamic forces acting on the blade. The optimization techniques of optimality criterion method and modified method of feasible directions have been successfully developed and applied to minimize the weight of rotating laminated blade. The effect of setting angles and rotating speed on the system dynamic behaviors as well as on the optimum design are also studied. The dynamic analysis shows that most of the bending modes can be significantly affected by rotating speed, setting angle, and the radius of disc. The results also indicate that the optimum weight will decrease with the increase of rotating speed for the multiple frequency constraints. The similar phenomena is also obtained for the dynamic response constraints. Moreover, the optimum weight of the dynamic response constraints case is higher than that of multiple frequency constraints case. This study presents that the weight of rotating laminated blade can be greatly reduced at optimum stage." @default.
