INTRODUCTION
This Data Item is the first in a series that deal with the
dynamic characteristics of cylindrical helical springs, comprising
both tension/compression and torsion springs. The assumptions and
limitations that apply to the calculation procedure are defined
together with the prescribed loading conditions assumed to apply to
the spring. The Item provides derivation of the deformation,
stresses and transverse loading on the spring and the form design
of the spring ends which will affect the loading characteristics.
The elastic stability of compression and torsion springs are
discussed and formulae given for ensuring stability.
In engineering practice cylindrical helical springs are used in
three different ways, as
compression springs,
tension springs and
torsion springs.
This Item contains design data for all three kinds of helical
spring as listed above. Provided that the following assumptions and
limitations are observed in the design process, the given methods
of calculation yield very close approximations to the actual
values.
