... increasingly frequent. LS allows the components to be designed with tunable stiffness, which can unlock the control of natural frequencies. However, crucial challenges must be faced to integrate LS into the typical design process. In this work, an experimental and numerical study of LS-enabled tuning...

... and surface roughness on the contact model and dynamic characteristics of the rotor is analyzed. Moreover, the experimental tests of natural frequencies and mode shapes are carried out. The results show that the proposed semi-analytical contact model is effective and more accurate compared to other elastic...

... between eigenfrequencies and experimental natural frequencies. In other words, while in the previous approach the disk was considered rigidly coupled with the shaft, in this case an additional node j , for a suitable graphical representation belonging to the plane orthogonal at the rotational axis...
