Abstract
(EN)
Disclosed are a multi-dimensional magnetic negative-stiffness mechanism and a multi-dimensional magnetic negative-stiffness damping system composed thereof. The multi-dimensional damping system is composed of a positive-stiffness mechanism (2), a multi-dimensional negative-stiffness mechanism, a floating frame (4), a body to be damped (3) and a mounting base (1), wherein the positive-stiffness mechanism (2) is a traditional elastic element, same is connected to the body to be damped (3) and the mounting base (1), and provides supporting forces in an X direction, a Y direction and a Z direction, and a basic damping function. The multi-dimensional negative-stiffness mechanism is composed of at least two negative-stiffness magnetic groups (6). Each of the negative-stiffness magnetic groups (6) can provide one-dimensional or two-dimensional negative stiffness. By means of a series connection of the at least two negative-stiffness magnetic groups (6), a two-dimensional or three-dimensional negative-stiffness effect can be achieved, and the damping performance of the system in multiple dimensions can be improved. By using the multi-dimensional magnetic negative-stiffness mechanism, a large force for bearing the body to be damped (3) is realized, and the function of multi-dimensional high-performance damping is also realized.

L'invention concerne un mécanisme magnétique multidimensionnel à rigidité négative et un système d'amortissement magnétique multidimensionnel à rigidité négative doté dudit mécanisme. Le système d'amortissement multidimensionnel est composé d'un mécanisme à rigidité positive (2), d'un mécanisme multidimensionnel à rigidité négative, d'un cadre flottant (4), d'un corps à amortir (3) et d'une base de montage (1). Le mécanisme à rigidité positive (2) est un élément élastique traditionnel, il est relié au corps à amortir (3) et à la base de montage (1), et assure des forces de support dans une direction X, une direction Y et une direction Z, et une fonction d'amortissement de base. Le mécanisme multidimensionnel à rigidité négative est composé d'au moins deux groupes magnétiques à rigidité négative (6). Chaque groupe magnétique à rigidité négative (6) peut assurer une rigidité négative unidimensionnelle ou bidimensionnelle. Une liaison en série des deux groupes magnétiques à rigidité négative ou plus (6) permet d'obtenir un effet de rigidité négative bidimensionnel ou tridimensionnel, et l'efficacité d'amortissement du système dans de multiples dimensions peut être améliorée. L'utilisation du mécanisme magnétique multidimensionnel à rigidité négative permet d'obtenir une force importante pour porter le corps à amortir (3), et une fonction d'amortissement multidimensionnel à haute efficacité est également obtenue.
