Abstract

This paper presents the results of a study in which a semi- active vibration suppression system is used to control vibrations in a machine excited by impulsive forces. The problem involves a machine, which is mounted to a flexible foundation, that sees an impulse excitation force. Given the flexibility of the foundation, the excitation causes significant vibrations in the machine. If the foundation could be sufficiently stiffened, the vibrations could be reduced to acceptable levels. However, such changes to the foundation are not possible for this application. Therefore the system is being redesigned to include a vibration suppression system. Because of the high forces and strokes involved, a semi-active system is studied and compared to a fully active optimal control approach to determine its limitations and feasibility for this application.
