Problem

10-3

A helical compression spring is wound using 2.5-

mm

-diameter music wire. The spring has an outside diameter of 31

mm with plain ground ends, and 14 total coils.

(a) Estimate the spring rate.

(b) What force is needed to compress this spring to closure?

(c) What should the free length be to ensure that when the spring is compressed solid the torsional stress does not

exceed the yield strength?

(d) Is there a possibility that the spring might buckle in service?

Expert Solution

Solution:- The given problem has been solved using the standard formulas and principles used in the design of helical compression springs. Standard data for spring wire material i.e. music wire has been taken from standard textbooks.

An as-wound helical-coil compression spring with infinite fatigue life is needed to resist a dynamic load that varies from 8.0 to 24.0 lbf at 45.0 Hz over a dynamic deflection of 0.3 in. Because of assembly considerations, the solid length of the spring cannot be more than 1.2 in. The spring should have squared and ground ends and is to be made from peened music wire. Upon closure, use a design factor of 1.2 guarding against yielding and a fractional...
