The invention relates to a novel quasi-zero stiffness vibration isolator and a design method, and belongs to the technical field of vibration isolators. The novel quasi-zero stiffness vibration isolator comprises a bottom flange seat, a top mounting flange is arranged vertically above the bottom flange seat, a middle flange is arranged between the top mounting flange and the bottom flange seat, and the middle flange is connected with the bottom flange seat through a plurality of supporting stand columns. The middle flange is connected with the top mounting flange through a plurality of Euler beams, a limiting sleeve is arranged in the middle of the bottom flange seat, a compression spring assembly is arranged in the limiting sleeve, and a top block connected with the top mounting flange is arranged at the top of the compression spring assembly. The quasi-zero stiffness vibration isolator has the beneficial effects that the quasi-zero stiffness vibration isolator can obviously reduce the vibration amplitude and the vibration attenuation time of an antenna and a feed source in a low-frequency band under the condition of meeting self mass and volume constraints, and vibration caused by flexible accessories in a spaceborne radar is effectively blocked.
