摘要

摘要: 水液压数字阀的阀芯工况恶劣,对材料的强度和耐磨性都有较高要求。针对水液压传动对数字阀元件的要求,从实用角度出发,采用氮化硅陶瓷材料制造阀芯,能够发挥其强度高、硬度大、耐磨性能好及不受腐蚀影响的优点,通过抗磨试验研究了氮化硅陶瓷阀芯的磨损情况,并通过Matlab/Simulink软件对装有陶瓷阀芯的水液压数字阀的动态性能及输入输出特性进行仿真分析。研究结果表明:用氮化硅陶瓷制造的水液压数字阀的阀芯耐磨性好、磨损率低;装有陶瓷阀芯的水液压数字阀具有良好的动态特性及输入输出特性。

Abstract: Working conditions of core in water hydraulic digital valve are quite adverse,and its material needs rather high requirements on strength and wearability.According to the requirements of digital valve components in water hydraulic transmission and from the practical standpoint,core manufactured with ceramic materials could bring its advantages of high strength,big hardness,good wearability,non-affection with corrosion.The wear case of Si3N4 ceramic core was studied by the wear-resisting experiment and the dynamic performance and the input and output characteristic simulation analysis of water hydraulic digital valve with the ceramic core was made by Matlab/Simulink software.The results show that the core manufactured with Si3N4 has high abrasion resistance and low wear rate and the water hydraulic digital valve with ceramic core has good dynamic characteristics and input/output characteristics.
