基于 ADAMS 的动力猫道扶持臂变幅机构优化设计

摘要

To make a study of supportive arm of one float power catwalk,the dynamic model of the amplitude variation mechanism of supportive arm is built by using ADAMS software,and the sim-ulation of supportive arm is done under the effect of 762 mm (30 inches)casing pipe.The force in the amplitude variation cylinder is obtained.With the aim of the least of the average load in simulation,the optimized position of the three pin-connected joints of the amplitude variation cyl-inder is obtained.The result indicates that average load of the amplitude variation cylinder has a obvious decrease in simulation with the optimized pin-connected joints,at the same time,the press concussion on the hydraulic system is reduced.This technique can be used in the optimization for the other petroleum machinery.%以某型号浮式平台动力猫道的扶持臂为研究对象，在 ADAMS 软件中创建扶持臂变幅机构的动力学模型，在762 mm（30英寸）套管的作用下对扶持臂进行仿真分析，得到变幅油缸受力曲线。在仿真过程中，以变幅油缸受力平均值最小为优化目标，求取变幅机构3个铰接点的最优位置坐标。分析结果表明：优化后的铰接点在仿真过程中明显降低了变幅油缸的受力，同时减小了对液压系统的冲击，此方法可用于其他石油机械的优化设计中。
