The rule of thumb “no active-on-active” states that a machine incorporating active vibration isolation (internally) cannot be mounted on a platform using active vibration control. This rule is ...
Disruption of a payload can be caused by three of the primary sources of vibration (or noise): ground vibration, acoustic noise, and direct force disturbances. Ground, or seismic vibration, is present ...
In order to demonstrate the generation mechanism of "combustion noise" separately from "mechanical noise," the process of transfer in which vibration travels to each engine portion was analyzed ...
