Simulation Analysis about Dynamic Characteristics of Crane's Jib System Based on the Lifting Loads

Abstract:

Given the importance of the jib system which has direct impact on the comprehensive performance of portal crane, this article regards the Jib system as a whole. Detailed finite element model of the jib system was established and vibration modes were calculated based on the finite element method. This paper conducted a transient dynamic simulation and obtained dynamic response to the boom structure in the process of lifting rated weight at the maximum amplitude position. This research approach is not only very useful to obtain dynamic response and assess the fatigue life of the jib system in the design phase, but also to provide a theoretical basis for the design of portal crane.
