Vibration Introduction OSH Answers

Vibration is the mechanical oscillations of an object about an equilibrium point. The oscillations may be regular such as the motion of a pendulum or random such as the movement of a tire on a gravel road. The study of health effects of vibration require measures of the overall "pressure waves" (vibration energy) generated by the vibrating

Vibration Isolation an overview ScienceDirect Topics

Table 10.5.1 depicts three vibration isolation problems that are defined according to vibration sources, namely, external excitation, base excitation, and rotating unbalance. The isolators in these problems are modeled as a pair of spring and damper. The steadystate response and transmissibilities in these problems have been given in Sections 10.5.1 to 10.5.3.

Stability Revisited Introduction to Digital Filters

Stability Revisited As defined earlier in §5.6 (page ), a filter is said to be stable if its impulse response decays to 0 as goes to infinity. In terms of poles and zeros, an irreducible filter transfer function is stable if and only if all its poles are inside the unit circle in the plane (as first discussed in §6.8.6).This is because the transfer function is the z transform of the impulse
