摘　　要：为了满足企业对集装箱波纹板焊接的需求,实现焊接时板材的精确定位控制,设计集装箱波纹板四缸同步举升器液压系统。使用AMESim软件构建包含伺服阀与外负载在内的液压系统位置控制系统模型。基于负载敏感性高的特点,采用平滑的惯性环节复合轨迹曲线为期望位移信号,以降低由于信号突变引起的液压缸不同步的影响;并通过合理补偿伺服阀死区来提高控制精度以及降低成本;对其进行仿真分析及实验验证。结果显示:通过采用比例伺服阀控制液压缸的同步方法,并结合积分分离PI及前馈的复合控制策略,动态同步误差可以控制在±0.4 mm以内,稳态同步误差可以控制在±0.3 mm之内,验证了设计的可行性。设计方案能够满足设备的研制要求,为实际生产过程提供了有力的支持。In order to meet the demand for welding corrugated panels for containers and achieve precise positioning control of the panel during welding,a hydraulic system for a four-cylinder synchronized lifting device for container corrugated panels was designed.Using the AMESim software,a hydraulic system position control system model was constructed,including a servo valve and external load.Based on the characteristics of high load sensitivity,the smooth inertial link composite trajectory curve was used as the expected displacement signal to reduce the influence of hydraulic cylinder asynchronous caused by signal mutation,and the dead zone of the servo valve was reasonably compensated to improve the control accuracy and reduce the cost.The simulation analysis and the experimental verification were carried out.The results show that using proportional servo valve to control the synchronization of the hydraulic cylinders,and incorporating a composite control strategy of integral-separate PI and feedforward,the dynamic synchronization error can be controlled within±0.4 mm,and the steady-state synchronization error can be controlled within±0.3 mm,the feasibility of the design is verified.The design scheme can meet the requirements of equipment development,providing strong support for the actual production process.
