Abstract

In order to analyze the influence of flexural stiffness on the frequency of short boom, the calculation accuracy of natural vibration frequency of short boom cable force is low. Based on the existing formula for calculating natural vibration frequency of the cable with fixed supports at both ends and considering the non-linear vibration of the cable, the finite element model considering the flexural stiffness of the derrick is established in combination with the finite element software in a practical project, and the influence of the flexural stiffness on the cable force of the derrick of different lengths is analyzed. The modified formula of theoretical frequency is fitted. The analysis shows that the flexural stiffness has a great influence on the recognition of the natural vibration frequency of the short boom, which leads to the low recognition accuracy in the short boom, and cannot be directly used to identify and judge the frequency of the short boom. According to different boom lengths, the theoretical frequency is fitted with the measured natural vibration frequency, and the correction formula of the first order natural vibration frequency is obtained. Compared with the traditional boom frequency calculation formula, the error of natural vibration frequency identification can be controlled within plus or minus 5% by using the revised formula.
