ANSYS1000T起重船扒杆强度分析

摘要本文根据《船舶与海上设施起重设备规范》（2007），采用 ANSYS workbench 软件建立 1000T 起重船扒杆结构的有限元模型，对扒杆结构在受重力载荷，风载等载荷并受船舶横倾和纵倾时的强度进行了分析计算，检查校验了起重船扒杆结构强度是否满足规范要求。介绍了如何建立有限元模型并针对各种工况对模型施加不同的载荷，最后进行分析计算。校验了起重船钢索绳部分和扒杆桁架结构的许用应力，计算了扒杆在不同倾角时的允许吊重。结果表明该起重船扒杆结构的各主要部件均满足规范中的强度和稳定性要求，并在软件结果分析中显示了扒杆结构的受力特点和最大应力分布区，为起重船扒杆结构的优化改进提供数据支撑，可针对性地对扒杆结构进行部分加固。79117

Abstract According to the "Code for ship and offshore installation lifting equipment" (2007), using workbench ANSYS software to establish the finite element model of the derrick mast structure of 1000T crane ship, analyze and calculate the strength of the derrick mast structure under the load of gravity load, wind load and the transverse and longitudinal dip of the ship, check whether the structural strength of the derrick is satisfied with the specification requirements。 This paper introduces how to establish the finite element model and to apply different load to the model under different working conditions, finally carries on the analysis computation。 Check the allowable stress of the wire rope and crane ship derrick mast structure and the allowable lifting weight of the derrick mast at different inclined angles is calculated。 The results show that the main parts of the derrick mast structure meet the requirements of strength and stability in the specification, the stress characteristics and the maximum stress distribution of the pole structure are also shown in the results of the software, provide data support for the optimization and improvement of the derrick mast structure, make the structure of the derrick mast can be partially strengthened。
