This paper presents a comprehensive study on the working principle and design concepts, of an inertial vibration absorber incorporating a flywheel seismic mass. The unit is formed by a seismic flywheel element, which is mounted on the base via a coupled liner-torsional suspension spring that couples the axial and rotational motions of the flywheel. In this way the axial inertia effect generated by the linear vibration of the flywheel is augmented by its rotational inertia produced by the coupled rotational vibration. The advantage of such design is twofold. Firstly, the inertia effect of the absorber can be increased without increasing the total weight of the unit. Secondly, the characteristic dimension of the device can be miniaturised. This work presents the working principles and the designs and manufacturing process based on additive 3D printing of different solutions. The paper shows that indeed the rotational inertia effect increments the vibration control performance of the absorber with now weight cost.

Abstract
This paper presents a comprehensive study on the working principle and design concepts, of an inertial vibration absorber incorporating a flywheel seismic mass. The unit is formed by a seismic flywheel element, which is mounted on the base via a coupled liner-torsional suspension spring that couples the axial and rotational motions of the flywheel. In this way the axial inertia effect generated by the linear vibration of the flywheel is augmented by its rotational inertia produced by the coupled rotational vibration. The advantage of such design is twofold. Firstly, the inertia effect of the absorber can be increased without increasing the total weight of the unit. Secondly, the characteristic dimension of the device can be miniaturised. This work presents the working principles and the designs and manufacturing process based on additive 3D printing of different solutions. The paper shows that indeed the rotational inertia effect increments the vibration control performance of the absorber with now weight cost.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
