ABSTRACT:
It is known that a sectional shape of a spring wire can be formed into an oval made by a semicircle and a semiellipse. However, it has been found that such a shape is not the best obtainable, and that stress distribution can be improved by increasing the diameter of the spring wire slightly in a portion where the stress is greatest, along the semielliptical surface. Parameters are disclosed for determining dimensions that result in increased energy efficiency.
