1. A mounting system for supporting rotating machinery, the mounting system comprising:
a base frame having an upper side for mounting the rotating machinery and a lower side;
a plurality of main supporting members, arranged according to a triangular arrangement and forming a three-point mounting arrangement defining a mounting plane, wherein the mounting plane of the plurality of main supporting members is parallel to a shaftline of the rotating machinery arranged on the base frame; and
a plurality of auxiliary supporting members, having a variable stiffness configured and arranged to generate a reaction force in a direction substantially orthogonal to the base frame,
wherein the plurality of auxiliary supporting members are configured so that when the base frame is subject to an overload exceeding a predetermined load under normal operating conditions and an extra-displacement beyond a predetermined displacement under the normal operating conditions occurs in a direction orthogonal to the base frame, the variable stiffness is increased to support at least a portion of the overload exceeding the predetermined load, and when the displacement of the base frame is equal to or less than the predetermined displacement, the variable stiffness has a stiffness less than the stiffness of the main supporting members, and
wherein the plurality of auxiliary supporting members are arranged in a position different from the position of the three-point mounting arrangement where the plurality of main supporting members are arranged.
