摘要
为解决大功率自由锻造油压机高能耗的问题,设计了一种开式变量泵控油压机系统。采用ADAMS和AMESim建立了开式变量泵控油压机系统联合仿真平台,对其常锻工况和快锻工况的控制特性进行了仿真研究。基于600kN锻造油压机实验平台,对其常锻工况和快锻工况的控制特性进行了验证,并将验证结果与仿真结果进行了对比。研究结果表明:开式变量泵控油压机系统能够满足技术要求,即常锻时操控性好,卸压无冲击,运行平稳;快锻(锻造频次80次/min)时,位置控制精度小于1mm。
In order to solve the problems of high energy consumption for huge free forging hy- draulic press, an open variable pump-controlled hydraulic system for oil hydraulic press was proposed. Firstly, combined with ADAMS and AMESim, a co-simulation platform of open variable pump-con- trolled hydraulic press system was built, and aiming at typical work modes, regular forging and fast forging, the control characteristics were studied by simulations. Secondly, based on 600kN forging hydraulic press experimental platform, control characteristics for the open variable pump-controlled hydraulic press with regular forging and fast forging was verified respectively by experiments, and compared with the simulation results. The simulation and experimental results approve that the open variable pump-controlled hydraulic press system can meet the technical requirements. For regular forging, it has a good performance about manipulation, low impact and stability. For fast forging, when the forging frequency is up to 80 times oer minute, the oosition control accuracy is less than 1 mm
