V-type torsion spring manufacturing.
V-type torsion spring manufacturing reading guide: JA4i2Ku know d = 4mm to meet the strength conditions. (3) Calculate the number of effective working cycles n. From the trial calculation (2), λmax=16.7mm, G=79000N/mm2 is obtained by the formula n=6.11, taking n=6.5 turns, and still refer to both ends and tightly one turn, n1=n+2=8.5. This calculation result satisfies the strength and stiffness constraints. From the aspect of size and weight, it is a better solution. This solution can be initially determined. The other dimensions are calculated and checked for stability.
