The invention relates to an apparatus for mounting an object to a structure. The apparatus includes an elastic arrangement including at least two elastic partial arrangements. The two elastic partial arrangements are arranged at a distance in the direction of a main axis, and the two elastic partial arrangements are soft in the direction of the main axis and stiff in all directions orthogonal to the main axis. Each of the two elastic partial arrangements comprises an inner connection area close to the main axis and an outer connection area farther away from the main axis, and each of the two elastic partial arrangements comprises at least two leaf springs which extend between the inner connection area and the outer connection area and which are spirally wound into each other within a common leaf plane.

Apparatus for mounting an object to a structure in a vibration-free manner

The invention relates to a device for mounting an object to a structure in a vibration-free manner. The device has an elastic arrangement that supports the object at the structure in a stiff manner in the directions of at least two of the total of six translational and rotational degrees of freedom and in a soft manner in the directions of at least one of the total of six translational and rotational degrees of freedom. Main modes of motion of the object in the directions of the rigid support have natural frequencies that are higher than any main mode of motion of the object in any direction of the soft support at least by a factor of ten. The soft support is undamped, and a damping device is provided for any main mode of motion of the object in any direction of the soft support.
