There are natural frequencies in all equipment that have components. Generally, they exist in the 8 to 200 Hz environmental spectrum. Figure 46.1 demonstrates the transmissibility and resonant ...

All complex and intricate assemblies include components with natural frequencies that are critical because they exist in the generalized 8 to 200 Hz environmental spectrum. This can be demonstrated by ...

At light loads an externally pressurized sleeve bearing tends to be stiffest, followed by rolling-element bearings and self-acting sleeve bearings. As loads increase, the rolling-element bearing ...

• Most problems are nonlinear from the get-go. • Simplified load-deflection cases can help explain nonlinear (structural) FEA. Which designers need nonlinear FEA and why? Actually, projects ranging ...

Spindles designed for machine tool applications, such as milling, grinding and turning, require the bearings to be set in preload to meet speed, stiffness and accuracy requirements. More importantly, ...
