基于AMEsim的电磁阀仿真与试验验证

电磁阀是液压系统中的控制元件,其阀芯运动特性直接影响液压系统的工作性能。针对阀芯运动的动态特性建模是液压系统检测诊断领域的重要研究方向。以液压系统典型的三位四通电磁换向阀为研究对象,开展了基于AMEsim软件的建模、仿真分析与试验验证研究。在对电磁阀工作机理和各功能模块的分析基础上,利用AMEsim软件中的电磁库与液压库构建了电磁阀仿真模型,对影响电磁阀阀芯位移的主要因素进行分析,给出了不同的路损、弹簧刚度及液压油黏度对电磁阀阀芯位移影响的量化对比曲线;设计并搭建了液压试验台对模型进行验证。试验结果显示,实测数据与仿真结果符合良好,最大相对误差为8.2%。研究工作为电磁换向阀故障诊断和优化设计提供了模型与数据支持。

Electromagnetic Valve Simulation and Experimental Verification Based on AMEsim

electromagnetic valve is hydraulic system actuator of controlled, the valve core movement directly affect the work performance of the system, In view of the dynamic characteristics of the movement of valve core modeling is an important research direction in hydraulic system detection diagnosis technology. In this paper, three position four-way electromagnetic valve for the study, carried out based on AMEsim software modeling, simulation analysis and experiment research.. Analysis working mechanism and each function of electromagnetic valve, using electro mechanical and hydraulic component design of AMEsim software to build the model of the electromagnetic valve. Using the established model, the factors affecting the electromagnetic valve spool displacement is analyzed, gives a different path loss situation, spring stiffness and hydraulic oil electromagnetic valve impact of spool displacement quantify curve. The hydraulic test bench was designed and built for test have been carried out to verify the simulation results. The simulation results consistent of test data, maximum relative error is 8.2%, the research work provide models and data support for electromagnetic valve fault diagnosis and optimization design.
