In this paper, a testing method to determine the modulus of elasticity of the wirerope based on random vibration is proposed. The wirerope and the hanging weight are simplified as a mass-spring of a single degree of freedom, the natural frequency of which is measured by the random vibration hammer testing method. Then the modulus of elasticity of the wirerope can be calculated according to the frequency. At the same time, the natural frequency can also be calculated by the longitudinal wave theory of elasto...
