vibration isolation theory and practice

Vibration isolation

Vibration isolation is the process of isolating an object such as a piece of equipment from the source of vibrations Vibration is undesirable in many domains primarily engineered systems and habitable spaces and methods have been developed to prevent the transfer of vibration to such systems

Recent Advances in Shock Vibration Isolation: An Overview

Mechanical shock is a common problem that is present in many situations such as ground motion blast explosions crash and impact The development of passive active or adaptive control and isolation strategies for shock-induced vibration has experienced recent interest typically due to the increasing demand in improved isolation requirements for sensitive equipment subjected to harsh

Theory of Vibration Protection

The passive vibration protection is based on vibration isolation vibration damping and dynamic absorbers Parametric vibration protection theory is based on the Shchipanov-Luzin invariance principle Optimal active vibration protection theory is based on the

What is the Theory of Vibration Isolation and

Vibration Isolation Theory: Unfortunately (but fortunately for noise control consultants) this is not always possible A typical problem is a rotating machine (such as a pump AC compressor blower engine etc) mounted on a roof or on a floor above the ground floor The problem is usually most apparent in the immediate vicinity of the vibration source

Vibration isolation theory and practice

Vibration isolation theory and practice - The need for vibration isolation is growing because of increasing vibrations and the requirement for higher spatial resolution Ingenious mechanical design allows passive systems to work with frequencies of the order of 1 Hz Modern accelerometers detect absolute motion and allow disconnection from the vibrations of the floor
