Active Isolation and Control of Vibrations. Edition No. 1
VDM Publishing House, March 2009, Pages: 160
This book investigates a solution for the
six-degree-of-freedom vibration isolation and
suppression. Both ground and space applications have
been taken into account. Vibrations propagating into
the mechanical systems can cause many problems at
different levels causing performance degradation for
sensitive systems. The proposed solution in this work
is to use a six-axis active hexapod based on Stewart
platform configuration. The rigidity of the legs of
this hexapod determines the application to be used
for; a stiff hexapod, for example, is used as a rigid
interface for active damping and precision pointing
applications while a soft hexapod is used, in
general, for the purpose of active isolation of
vibrations. Active vibration isolation and damping of
sensitive equipment is investigated here where
several single-axis isolation techniques are analyzed
and tested. The study of single-axis systems has been
developed and used to build a six-axis isolator. A
six degrees of freedom active isolator based on
Stewart platform has been designed, manufactured and
tested for the purpose of active vibration isolation
of sensitive payloads.
