[0056] Example: The width of a certain end-contact type few-piece parabolic variable-section primary and secondary springs is b=60mm, the modulus of elasticity E=200GPa, and half of the installation distance l 3 =55mm; Among them, the number of main reeds m=2, half the length L of each main spring M =575mm, the thickness h of the straight section at the root of the main spring 2M =11mm, the distance l from the root of the parabolic segment of the main spring to the end point of the main spring 2M = L M -l 3 =520mm; Thickness h of the straight section at the end of the first main spring 11 =7mm, the thickness ratio of the parabolic segment of the first main spring to β 1 = h 11 / h 2M =0.64; the thickness h of the straight section at the end of the second main spring 12 = 6mm, the thickness ratio of the parabolic segment of the second main spring to β 2 = h 12 / h 2M = 0.55. Number of secondary reeds n=1, half length L of secondary reeds A =525mm, width b=60mm, half o...
