摘　　要：以某小型锚艇为例,利用有限元软件,参照《船舶及海上设施起重设备规范》(2007)的有关要求,在有风起锚、无风起锚和试验三种工况下,对其支撑结构及羊角的强度进行仿真计算,并提出了一种校核旋转稍直径的方法。在此基础上,对羊角结构的板厚进行优化,并对比了优化前、后模型的应力情况。计算结果表明:羊角优化后的模型强度依然满足要求,经优化后的羊角能有效地减少了钢材建造用量。Taking a small anchor boat as an example,using finite element software and referring to the relevant requirements of the Code for Lifting Equipment of Ships and Offshore Installations(2007),under the three working conditions of wind anchoring,non-wind anchoring and test,the strength of its supporting structure and sheep's horn are simulated and calculated,and a method to check the slightly diameter of rotation is put forward.On this basis,the thickness of the sheep horn structure is optimized,and the stress of the model before and after optimization is compared.The calculation results show that the strength of the optimized sheep horn model still meets the requirements,and the optimized sheep horn can effectively reduce the amount of steel construction.
