This section will show the wear morphology of the alloy. Figure 8 shows the morphologies of the Mn-Cu alloy with different weaving parameters in which the normal force is 2 N, the sample thickness is 0.3 μm, …
Web2 de mar. de 2024 · However, the stiffness and damping of the air film are frequency-dependent, making the commonly used approach of taking static stiffness or fixed value as the spring coefficient no longer applicable for a bearing subject to a complex external force containing different frequencies. WebIt was found that the dynamic stiffness of dry joints is independent of frequency and no energy dissipation is measurable. The stiffness is primarily a function of pre-load and surface finish, with apparent joint area becoming important only for …
WebAs previously shown, stifness and damping are not identical for each amplitude and are therefore largely dependent upon the vibrational behaviour of the system. That means stiffness and damping can only be given exactly for one excitation frequency with use of the PELAS or PBUSH card. Web1 de mar. de 2000 · Dynamic stiffness and damping in the context of flat joints are also discussed in this chapter. However, as in other parts of the book, inertia effects are typically ignored even for dynamic cases giving one the impression that static considerations alone are sufficient for design purposes.
