中文摘要:
      为提高高海况下救助打捞成功率与起吊过程安全性,介绍一种基于高海况柔性网具救助打捞系统的方法,提出一种以变幅油缸为执行机构的主被动复合波浪补偿方案,采用模糊自适应PID算法控制器,控制变幅油缸伸缩位移,抑制船舶横摇对伸缩吊臂的影响。根据相似准则对打捞系统进行模型设计并建立波浪补偿系统缩比模型试验,通过液压摇摆台模拟船舶横摇角度,测试变幅油缸的响应时间、运动的平稳性及缩比模型的补偿精度,预测原型样机的波浪补偿效果。实验结果表明:模型试验系统运行稳定可靠,补偿效果良好,打捞吊机跟随模拟平台做-15°~+15°的正弦摇摆,吊臂的波浪补偿运动误差维持在±1°内。该方法原理和试验数据可为原型样机的设计提供参考。
英文摘要:
      In order to improve the success rate of salvage and safety of lifting process in high sea conditions, a method of flexible net salvage system was introduced, and a kind of active and passive composite wave compensation scheme was presented. The fuzzy adaptive PID algorithm was used to control the displacement of hydraulic cylinder, and to suppress the influence of ship rolling on the crane arm. According to the similarity criterion, the model of the salvage system was designed and the scale compensation model of the wave compensation system was established. The hydraulic swing platform was used to simulate the ship roll angle, the wave compensation effect of the prototype was predicted by testing the response time, the motion smoothness and the compensation accuracy of the scale model. The experimental results show that the system is stable and reliable; under the condition of 15° sine swing motion of the swing platform, the wave compensation motion error of the crane boom is maintained within ± 1°. The method theory and test data of the scale model can provide reference for the design of prototype.
