Abstract

Vibration control systems are described which provide for the variation in stiffness and damping in a structure. The systems are based on the use of rheological fluid, with examples provided of magnetorheological fluid flex actuators and semi-active damping systems. An adaptive vibration control system is also described incorporating sensors, a signal processor and a power supply together with the fluid flex actuators and semi-active damping systems. Embodiments are described for use in and with skis.
