Sažetak
The paper considers the surge of a helical spring, retained at one end and controlled by a cam at the other end. The periodic lift function of the cam was approximately replaced by the Fourier polynom. The forced displacement amplitudes were determined for each harmonic of this polynom. The theory of forced longitudinal vibrations of a bar with continuously distributed mass, elasticity and damping was applied to simulate the motion of spring coils. It was found out that two or more modes may consist concurrently in the spring. This was obtained by analysing mathematical formulas and by comparing computed and published measured results. The line spectrum of the Fourier series was introduced as a useful tool for estimating the influence of the high order harmonics on the spring surge.
