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

The invention belongs to the technical field of vertical rigidity calculation of oval-section wire diameter type truncated-cone-shaped spiral springs, and particularly relates to a method for calculating the vertical rigidity of an oval-section wire diameter type truncated-cone-shaped spiral spring. According to the method, the vertical rigidity of the oval-section wire diameter type truncated-cone-shaped spiral spring can be calculated under the condition that the oval-section mass center coordinate offset is considered according to the structure parameters and the material characteristic parameters of the oval-section wire diameter type truncated-cone-shaped spiral spring. ANSYS simulation and test verification of a prototype show that an accurate and reliable calculated value of the vertical stiffness of the oval-section wire-diameter type truncated-cone-shaped spiral spring can be obtained by using the method, the vertical stiffness is ensured to meet the design requirement, a reliable technical foundatio
