Establishment of a Spring Design Formula for Low Temperature Use of Spring

Abstract

Normally the springs are designed for room temperature conditions and the equations of elasticity are used to correlate the spring parameters. However, when the spring are required for use at low temperatures, these equations do not hold fairly good for design purpose. In this paper the establishment of new formula, that can be used for designing the springs for use at low temperature conditions has been discussed. Tests have been carried out at 20 degree calcius and -40 degree calcius to check the reliability of this formula. The formula has given satisfactory results.
