Fully Pneumatic Semi-Active Vibration Isolator Design And Analysis, Hans William Schaeffer

Graduate Theses and Dissertations

The research presented in this thesis provides a methodology of designing, modeling and controlling a fully pneumatic semi-active vibration isolator system. The prototype vibration isolator system has the ability to adjust the damping and natural frequency characteristics of the system. It consists of an air spring, a variable orifice valve, and an accumulator. In this conguration, the spring characteristics are provided by the air spring and accumulator, while the variable orifice valve provides the damping characteristics. The valve is computer regulated according to the innovative control laws that were developed for the pneumatic system. The

vibration isolator system is designed ...
