  • Patent number: 10962082
    Abstract: Provided is an adjusting method for a resonance frequency of a vibration isolator, the vibration isolator including first to n-th elastic member groups and/or an n+1-th elastic member group, the first to n-th elastic member groups and/or the n+1-th elastic member group being located on an xy plane of an xyz coordinate system, and an xy coordinate system of the xyz coordinate system being a coordinate system obtained by, when a tensor of inertia I with respect to an XYZ coordinate system having an origin in a center of gravity of a vibration sensing side structure or a vibration source side structure is represented as I, rotating an XY coordinate system by ?=tan?1(2IXY/(IXX?IYY)) around a Z axis, the adjusting method including, when rigidity Ki of the first to n-th elastic member groups is represented as [ K i ] = [ k i ? _ ? xx 0 0 0 k i ? _ ? yy 0 0 0 k i ? _ ? zz ] , rigidity Kn+1 of the n+1-th elastic member group is represented as [ K n + 1
