摘要

In order to optimize the system parameters and prevent the glass cutting machine from crawling and a-void speed instability during usage , it designs a principle diagram of the hydraulic transmission system , builds the system main parameters and hydraulic cylinder structures .According to the principle of hydraulic system , it establishes the mathematical model , obtains the simulation model through applications of AMESIM software .The simulation decribes the each stage of work pressure and velocity variation curves .The results show that the glass cutting machine hydraulic system is responsive with the pressure and velocity in each stage of work .This is in a-greement with actual operation results , and meets the requirements of machine tool performance .%为了优化系统参数，防止玻璃切割机在使用过程中发生运动部件爬行、运动速度不稳定的现象，首先根据使用要求拟定了液压传动系统原理图，确定了系统主要参数及液压缸的结构，然后利用液压系统原理建立了数学模型，并以此为基础利用AMESIM仿真软件建立了仿真模型，通过仿真得到了系统工作各阶段压力变化曲线、速度变化曲线。仿真结果表明，玻璃切割机液压系统工作各阶段压力、速度响应迅速，工进开始时速度波动幅度较大，但很快趋于稳定，与实际运行结果吻合，满足机床使用性能要求。
