Method for calculating vertical rigidity of rectangular-section wire-diameter truncated-cone-shaped spiral spring

The invention belongs to the technical field of calculation of vertical rigidity of rectangular-section wire-diameter truncated-cone-shaped spiral springs, and particularly relates to a method for calculating the vertical rigidity of a rectangular-section wire-diameter truncated-cone-shaped spiral spring, and the vertical rigidity of the rectangular-section wire-diameter truncated-cone-shaped spiral spring can be calculated according to structural parameters and material characteristic parameters of the rectangular-section wire-diameter truncated-cone-shaped spiral spring, namely according to the number of effective turns of the spiral spring. The vertical rigidity of the rectangular-section wire-diameter truncated-cone-shaped spiral spring is calculated according to the parameters of the spiral spring, the effective height, the pitch diameters of the head end and the tail end of the spiral spring, the width and the thickness of the wire-diameter rectangular section, the elastic modulus, the Poisson's ratio a
