摘　　要：某步进式冷床升降油缸的同步由同步马达来控制,但在使用过程中经常会出现严重不同步情况。在对液压原理分析的基础上,利用AMESim对其液压系统进行模拟,发现原设计存在缺陷。在负值负载的工况下同步马达接在进油侧同步效果会很差,尤其是载荷比较大且存在偏载的情况。根据分析结果对原理进行了修改,并做了模拟。按照新原理对冷床液压系统进行改造,实际同步情况良好,问题得到了解决。A step type tilting cooling bed lifting cylinders synchronization is controlled by hydraulic synchronous motor, but in the use process it often appears serious out of sync. Based on the analysis of the hydraulic principle using AMESim software we find the defect of the original design. In the case of negative load and synchronous motor in the feed side synchronous effect will be very poor, especially the load is bigger and the partial load exists. The principle is changed according to the results of the analysis. According to the new principle the hydraulic system is modified, and the actual synchronization is in good condition.
