Experimental verification of stability of optimal compression helical springs

Jacek Krużelecki
In the paper, the experimental verification of stability of the optimal compression springs is presented. The optimal cylindrical spring is simply supported at both ends and the distribution of helix angle (variable pitch) ensures the maximal critical force. The theoretical results of optimization presented by Kruzelecki (1995), (1996) are compared with the experimental ones and buckling experiments confirm the theory presented.
