The book "Active Isolation and Control of Vibrations" offers a comprehensive examination of solutions for the active isolation and control of vibrations in mechanical systems. It addresses applications in both terrestrial and space contexts and highlights the challenges posed by vibrations that can penetrate sensitive systems. These vibrations can impair performance and lead to various issues. The proposed solution is based on a six-axis active hexapod, which is built on the Stewart platform configuration. The stiffness of the legs of this hexapod determines the specific application, with rigid hexapods used for active damping and precise alignment applications, while softer hexapods are designed for the active isolation of vibrations. The book analyzes and tests various techniques for vibration isolation and provides valuable insights into the development of a six-axis isolator designed for the active isolation of sensitive loads.
