摘　　要：针对前混合磨料射流设备存在连续性差和后混合磨料射流系统磨料混合不均匀等问题,基于电磁磨料浆体射流技术,采用数值模拟分析和实验研究相结合的方法对影响电磁磨料浆体射流增压特性因素进行深入研究。依据前人研究结果,采用数值模拟预测磁通密度和电压两参数对导电介质出口速度及其动能影响情况,搭建了试验平台。结合正交试验特点,进行试验。试验表明:磁通密度对射流增压特性影响最大,电压次之,验证了数值模拟分析结果。在磁通密度为0.7 T、电压值为72 V、导电介质浓度选为18%、极板间距为0.025 m情况下,射流增压特性效果最好。According to the problems which is poor continuity in the pre mixed abrasive jet equipment,uneven abrasive mixing in the rear mixed abrasive jet system,Etc.The paper is based on the electromagnetic abrasive water jet technology.The method of combining numerical simulation analysis with experimental research,which is used to study the factors affecting the supercharging characteristics of the jet of electromagnetic abrasive slurry.According to the results of previous studies.The influence of conduction medium exit velocity and kinetic energy is predicted by numerical simulation,which is caused by two parameters of magnetic flux density and voltage.Test platform is set up,and the experiment is carried out in combination with the characteristics of orthogonal test.The test show that the flux density has the greatest influence on the characteristics of the jet turbocharging,and the voltage is second.The results of numerical simulation are verified.The magnetic flux density is 0.7 T,the voltage value is 72 V,the concentration of the conductive medium is 18%,the distance of the plate is 0.025 m,the effect of the jet pressurization is the best.
