摘要
设计了一种新型转阀,继而得到一种转阀式液压激振器,并以转阀式液压激振器工作原理为基础,建立AMESim仿真模型.针对激振器工艺参数(频率、油压、油量、参振质量)匹配复杂的问题,基于Design-Expert建立了以工艺参数为因子、峰值位移为响应值的模拟实验方案,进一步利用中心组合试验设计(Central Composite Design,CCD)结合响应面的优化设计方法对模拟实验结果进行分析,通过模块寻优获得最佳峰值位移为3.2 mm时的最佳工艺参数匹配组合:频率为18 Hz、油压为9.5 MPa、油液流量为45 L/min、参振质量为890 kg,可为矿物筛分工艺参数的选择提供参考.
A new type of rotary valve is designed,and then a rotary valve type hydraulic vibration exciter is obtained. Based on the working principle of rotary valve type hydraulic vibration exciter,the AMESim simulation model is established;Based on Design-Expert,a simulation experiment scheme with process parameters(frequency,oil pressure,oil quantity,vibration mass) as response factor and peak displacement as response value is established;The simulation results is further analyzed by CCD( Central Composite Design) surface response method. By module optimization,the best process parameter matching combination when the best peak displacement is 3.2 mm is obtained: The frequency is 18 Hz,the oil pressure is 9.5 MPa,the oil flow rate is45 L/min,and the parameter mass is 890 kg. Which can provide a reference for the selection of technological parameters in mineral screening.
