为了提高浮式起重机篱笆式卷筒结构设计的安全性和可靠性,分析了包括筒体压力、端板压力和棘爪力在内的多层钢丝绳缠绕作用下卷筒体的受力情况,利用有限元技术计算了筒体-端板的结构强度和变形。同时给出了目前常用的稳定性计算方法,根据有限元法得到了卷筒在承受径向外压力、横向力作用下的整体稳定性,并对各种计算方法进行了比较。研究工作为结构优化设计提供了分析手段和参考依据。 In order to improve the safety and reliability of the design of the hedge-mounted roll structure of floating cranes, the force of the roll body under the action of multi-layer steel wire rope winding including the cylinder pressure, the end plate pressure and the pawl force is analyzed. Finite element technique calculates the structural strength and deformation of the cylinder-end plate. At the same time, the commonly used method of stability calculation is given. According to the finite element method, the overall stability of the drum subjected to radial external pressure and lateral force is obtained, and various calculation methods are compared. The research work provides the means of analysis and reference for structural optimization design.
