摘　　要：某型号贴面热压机在工作过程中出现液压冲击现象,为此,在不改变液压系统结构的条件下,考虑通过延长阀口的关闭时间来减弱液压冲击。利用AMESim软件建立液压管路仿真模型,保持管路长度不变,设置阀口关闭时间,比较不同时间下液压冲击的变化规律。改变管路长度,设置阀口关闭时间,比较不同管路长度下液压冲击随时间变化的规律。研究结果表明,当管路长度小于10 m时,在10~100倍相长的阀口关闭时间内,液压冲击减弱效果明显,液压冲击下降到相同水平,但长管路需要更长的阀口关闭时间。A lamination hot press experienced the phenomenon of hydraulic impact during operation.For this reason,without changing the structure of the hydraulic system,it is considered to extend the closing time of the valve port to attenuate hydraulic impact.The software AMESim is used to establish a simulation model of the hydraulic pipeline,the length of the pipeline remains unchanged,the closing time of the valve port is set,and the changes of the hydraulic impact under different times are compared.The length of the pipeline is changed,the closing time of the valve port is set,and the changes of the hydraulic impact with time under different pipeline lengths are compared.The research results show that,when the pipeline length is less than 10 m,within a valve port closing time of 10 to 100 times,the hydraulic impact is attenuated obviously and drops to a same level,but long pipelines require a longer valve port closing time.
