Abstract:

In this study, the freedom of vibration of the variable cut isotropic curve was studied. Since the chosen curve width is superior variable, the managerial equations have been reduced to adjacent differential equations for similar cutting geometers in space coordinates. Initial vibration analytical solutions are calculated separately for all boundary conditions, including anchor, simple mesnet and free-end. Mod shapes and natural frequencies are found for each limit condition. The results show that the change in the curve cut affects mode shapes and natural frequencies. The frequency of the vibration increases in the cuts that are shrinking, while the cuts that are shrinking are reduced.
