摘要
针对半固态镁合金成型机注射液压系统建模难度高、难以获取关键元件的实际结构参数导致仿真模型精度低、注射液压系统的动态特性分析难度大等问题,通过测量注射液压系统关键元件的三维模型,采用AMESim仿真平台建立各关键元件的仿真模型,并根据原理图完成整个回路搭建,通过成型机空载试验对仿真模型的正确性进行验证;最后,基于注射液压系统仿真模型对注射时油缸的注射和刹车特性进行分析.结果表明:仿真模型能准确模拟注射液压系统动态曲线的变化规律,最大相对误差在 5%以下.仿真模型能正确模拟注射液压系统的动态特性曲线变化情况,为注射液压系统动态性能的分析奠定了基础.
Abstract
Aiming at the problems such as high modeling difficulty of injection hydraulic system of semi-solid magnesium alloy molding machine,low accuracy of simulation model due to difficulty in obtaining actual structural parameters of key components,and difficulty in analyzing dynamic characteristics of injection hydraulic system,simulation models of key components were established by measuring 3D models of key components of injection hydraulic system and using AMESim simulation platform.The whole circuit was built according to the principle diagram,and the no-load test of the molding machine was carried out to verify the correctness of the simulation model.Finally,the injection and braking characteristics of the cylinder during injection were analyzed based on the simulation model of the injection hydraulic system.The results show that the simulation model can accurately simulate the dynamic performance of the injection hydraulic system,and the maximum relative error is less than 5%.The simulation model can correctly simulate the dynamic characteristic changes of the injection hydraulic system,laying a foundation for the analysis of the dynamic performance of the injection hydraulic system.
