The invention discloses a vibration double-control three-dimensional vibration isolation combined supporting component with a negative Poisson's ratio effect. The vibration double-control three-dimensional vibration isolation combined supporting component comprises a friction pendulum support, an NPR bidirectional damper and a vertical vibration isolation component. When vertical micro-vibration occurs, the vertical vibration isolation effect is achieved under the action of the weak vibration steel spring assembly; when horizontal strong vibration and vertical strong vibration occur, the NPR two-way damper consumes energy through the horizontal reciprocating motion characteristic of the NPR two-way damper, and when displacement is further increased, the variable-diameter part with the radial size increased in the middle moves into the mounting cavity, so that the distance between the mounting cavities is increased, and therefore the strong vibration steel spring assembly enters a working state; the effect of
