摘要:
为研究振动参数对双层等厚筛筛分效率的影响，采用离散单元法(DEM)模拟5种不同粒径的颗粒在不同振幅、筛面倾角、振动频率下的筛分过程。运用多项式逼近方法对仿真结果进行曲线拟合，得到拟合度最好时的筛分效率与振动参数关系图。最后，选出最好筛分效率下的振动参数进行正交试验。结果表明:双层等厚筛筛分效率最优的参数组合为振动幅度7mm、振动频率14Hz、筛面倾角17°。
Abstract:
In order to study the influence of vibration parameters on the screening efficiency of double-layer equal-thickness screen, the screening process of 5 kinds of particles with different particle sizes was simulated with the discrete element method (DEM) at different amplitudes, inclination angles and vibration frequencies. The curve fitting of the simulation results was carried out by using the polynomial approximation method, and the relationship between the screening efficiency and the vibration parameters was obtained when the fitting degree was the best. Finally, the vibration parameters at the best screening efficiency were selected for orthogonal test. Results show the optimal parameter combination of screening efficiency of double-layer equal-thickness screen is when the vibration amplitude is 7 mm, the vibration frequency is 14 Hz, and the inclination is 17 degrees.
