Abstract

This paper discusses an approach for the design of compression closely c:oild helical springs subjected to axial load. With the presented proposed method, one can specify the significant characteristics of the spring that contains the least possible volume of material while still providing suff-icient strength and stiffness. To do so, the classic design equations are developed so that they can be graphically represented in a (weight-diame-ter)-plane from which the global optimum design point can be determined. Also, a computation flow chart is given, as an alternative way to the graphical method. Based on the computation flow chart, a digital computer program can be written for the optimum design problem.
