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 eects, the axial and shear deformations and cross-sections of dierent shapes having double symmetry have been included in the
Equations of motion are developed for a helical spring, and solved to obtain the frequency and shape of each natural mode by the assumed mode method in which series of shape functions are used to represent the displacements. Computed harmonic solutions yield as many natural frequencies and mode shap
