Damping due to Creep in a Vibrating Helical Spring,

Abstract

The development of suiable and reliable equipment for measurements of static and vibratory properties of helical auminum springs at high temperatures is described. The results of a tes series of preliminary character and of a test series under improved conditions are given in graphic representations. The orders of magnitude involved for series I and II are (approximate values): temperature, 350 and 560 F;AND DAMPING PER CYCLE, 13 AND 5%, respectively, at spring constants of 2 lb/in., loads up to 1.4 lb, creep rates of 0.001 to 0.1 in./sec, and frequencies of vibrations of 4 c.
