Abstract

The transfer matrix method and the complementary functions method have been employed in the free vibration analysis of helical springs of irregular shape. The rotary inertia effects, the axial and shear deformations and cross-sections of different shapes having double symmetry have been included in the analysis. The formulation has yielded the exact free vibration frequencies of non-cylindrical coil springs. (C) 1997 by John Wiley & Sons, Ltd.
