Abstract:
An active vibration absorber assembly for use with a base, said active vibration absorber comprising:(a) a casing providing a primary tuning mass, said casing including a first housing and a second housing,(b) a first tuning mass flexibly supported relative to said first housing,(c) a first active force generator which is actively vibratable to vibrate said first tuning mass in a first direction,(d) a second tuning mass flexibly supported relative to said second housing,(e) a second active force generator which is actively vibratable to vibrate said second tuning mass in a second direction which is generally orthogonal to said first direction, and(f) a flexible member adapted to flexibly suspend said casing from the base such that vibration of said casing is constrained substantially solely by said flexible member,(g) wherein said first and second housings are rigidly connected.
