Abstract (en)
The damper consists of a complex pendulum of reduced height, being some 40 per cent lower than a simple pendulum of the same frequency, made by raising its imaginary centre of rotation. It consists of a secondary weight (m1) connected to a spring (L1) of stiffness (k), to which a pendulum of length (L2) supporting a weight (m2) is attached. The spring (L1) can be in the form of a steel strip fixed at its lower end and equipped at its upper end with an articulated joint. The movement of the weight (m1) on its spring allows the imaginary centre of rotation about which weight (m2) is balanced to be raised, while the period of the pendulum is easily adjusted by modifying the stiffness of the spring.
