全自动液压压砖机是集机、电、液、气、计算机技术和陶瓷工艺技术高度一体化的高科技专用设备,也是当代世界陶瓷墙地砖生产线上最关键的装备。随着陶瓷工业技术的不断进步和发展,对陶瓷墙地砖自动液压压砖机液压系统的稳定性,可靠性、精确性及易操作性提出了越来越高的要求,对液压传动与控制系统的性能和控制精度等也提出了更高的要求。
本文基于改善全自动液压压砖机液压系统的动态特性,针对WL3200T全自动液压压砖机液压系统,采用AMESim建模,建立WL3200T全自动液压压砖机压制过程的模型,并对此模型进行仿真实验,得出系统压制部分活塞运动速度和液压缸压力的动态特性曲线,为全自动液压压砖机系统设计和参数优化提供了依据。本文主要从以下几个方面进行研究并取得了一些成果。
分析了WL3200T型压机液压系统的油路,对压机的工作原理及动作控制进行了初步的研究。
以液压元件性能曲线为基础,运用AMESIM建立液压系统各相关液压元件的模型,进行仿真实验研究。验证理论的准确程度,反复修改数学模型,得到与实际非常接近的结果,把这个理论模型作为改进和设计类似元件或系统的依据。
建立WL3200型压机液压系统压制的模型,并进行仿真实验,确立一套压机系统仿真模型,为以后进行类似的仿真提供参考,通过仿真实验,确定参数的调整范围,从而缩短液压系统的调试时间,达到节省时间,提升效率的目的。
分析液压系统动态特征的主要参数,得出一些重要的性能曲线,对了解压砖机液压系统主油缸的压制力、活塞运行速度、动作时间及活塞的行程等参数以及各个元件间相互影响等起到重要的作用,从而为进一步的完善和提高现有的压砖机液压系统的动态性能提供理论依据。
Automatic Hydraulic Press is a High-tech equipment with the integration of machine, electricity, liquid, gas, computer technology and ceramic technology. It is also the most critical equipment of the ceramic wall and floor tiles production line in the modern world.

The hydraulic transmission and control system performance and control accuracy are also put forward higher requirements.
Based on full-automatic hydraulic press to improve the dynamic characteristics of the hydraulic system, for WL3200T hydraulic system, using AMESim modeling, the process model for WL3200T automatic hydraulic press was set up. Then suppressed part of the piston velocity and dynamic characteristic curve about the Automatic Hydraulic Press were get, and provides the basis parameter and

Based on the performance curve, AMESim was used to create models related the hydraulic system. Through simulation experiments, to verify the accuracy comparing the simulation results with experimental results and repeated amending to the model, until the experimental results is very close to this model, then make the model as a design improvement and similar components .
Set up the hydraulic system model for the WL3200-type.Then the simulation was used for the simulation after a similar reference. Determine the parameters of the adjustment range, which reduce the hydraulic system debug time for the purpose of saving time, enhancing the efficiency, and achieving the aim of the simulation.
The main parameters about the dynamic characteristics of the hydraulic system were analyzed. It can obtain a number of important performance curve .Through the dynamic simulation about the hydraulic system of the suppression, the relationship among the parts and parameters such as the suppress force of the main fuel tanks, piston speed, action time and piston stroke were know. And these are the theoretical basis for improving the performance of the existing hydraulic system.
