Lateral Compression of Helical Spring Model

抄録

Considering the scarceness of papers treating of the lateral behaviour of the helical spring of textile materials, in this paper is studied its lateral compressive behaviour when the helical spring is made of heat-set nylon gut.
It has been revealed that the lateral compressive force P per one pitch of the helix can be expressed as follows: P=2(P₁+P₂-P₀) where P₁ is the force due to the bending deformation, P₂ the force due to the torsional deformation and P₀ the negative force due to the original curvature.
