摘　　要：目前国内对大型液压设备的工作台面要求越来越大,精度要求越来越高,尤其是四角调平精度,现在只有极少数国家有能力设计制造能够满足要求的液压设备,但费用比较高。文中通过多轴同步控制技术和液压比例伺服控制技术相结合,使YT71S-3500玻璃钢液压机的四角调平精度控制在0.05 mm以内,达到了国际先进水平,结束了高端液压设备完全依靠进口的局面,增强了国产大型液压设备在国际市场的竞争力。At present,the demand for the working table of large hydraulic equipment becomes larger and larger,and the precision requirement is getting higher and higher in China,especially for the precision of four corners leveling.Although only few countries have the ability to design and manufacture the hydraulic equipment that can meet the requirements,the cost is much expensive.By applying multi-axis synchronization technology together with hydraulic proportional servo control technology,the four corners leveling precision of YT71S-3500 FRP hydraulic press is controlled to 0.05 mm or less.This technology reaches the international advanced level,brings it to the end for the situation that high end hydraulic equipment mainly depends on import,and enhances the competitiveness of domestic large hydraulic press in the international market.
