The invention discloses a debugging method of an inclined quasi-zero stiffness vibration
isolator with a
single pair of
diagonal rods and compression springs. A reference compression spring is obliquely arranged in the longitudinal vertical direction, two
diagonal rods are symmetrically arranged on the two sides of the reference compression spring, the top ends of the
diagonal rods are hinged, the bottom ends of the diagonal rods are hinged to a sliding block, and the inclined compression springs are connected between the sliding block and a support. The sliding block is limited to do low-friction reciprocating rectilinear motion in an inclined plane which forms an included angle with the horizontal plane; the oblique compression spring and the oblique rod generate
negative stiffness and are connected with the positive stiffness of the reference compression spring in parallel to generate the quasi-zero stiffness characteristic in the oblique movement direction; determining an initial state,...,; constructing a dimensionless formula, adjusting according to parameter conditions of the quasi-zero stiffness characteristics to obtain nonlinear quasi-zero stiffness characteristics, constant-value zero stiffness characteristics and constant-value quasi-zero stiffness characteristics; a
force displacement curve is drawn, the applied force is located at a static balance position, the force is divided by the
gravitational acceleration to be equal to the borne
vibration isolation mass, and whether the design requirements of the borne
mass and the
vibration isolation frequency band are met or not is judged.
