Study of Ultimate Load Capacity at Riveted Nodes of Holding Pole
摘要
The ultimate load carrying capacity of the holding pole nodes is one of the decisive factors to measure the load carrying performance of the holding pole. In order to study the ultimate load carrying capacity of riveted connection nodes of holding pole, the overall forces of holding pole under different working conditions were calculated and analysed based on the finite element method, so that the real force information of the nodes were extracted, and the force forms and regulations of the nodes were investigated. Based on this, the simulation of the node force characteristics was carried out, and the node ultimate load capacity test was carried out using a five-axis linkage hydraulic loading device, and the reliability of the numerical model was verified through the comparative analysis of the test and simulation results. By adjusting the riveting layout, the design of riveted joint nodes was optimised, the ultimate load capacity of the riveted nodes of the holding pole was increased up to 10.9%.
