Abstract: The free vibration along the horizontal direction of the vertical hanging spring-mass system has been studied with experimen-tal method.It is observed that the period decreases with the increasing of vibration amplitude and the height of spring suspension point. Data analysis reveals that the result of the theoretical calculation of nonlinear vibration model using the equivalent mass approximation is in accordance with the experimental data.It is found that the equivalent mass coefficient of this vertical hanging spring-mass system is smaller than that of the same spring-mass system processing simple harmonic vibration and this coefficient is related to the maximum tensile length of spring.
