The Numerical Modeling And Motion Simulation On The Feeding System Of Rubber Roller Husker

In order to meet the needs of large-scale production line, the development of large quantity rice processing equipment is imminent. The Rubber Roller Husker plays an important role among the rice hulling equipment, and its hulling technology is the most main link in rice processing technology, which means that we must increase the rice milling efficiency and improve production under the condition of the structure remains the same.The feeding system design of Rubber Roller Husker is directly related to the whole equipment working efficiency and performance. The electromagnetic vibration feeder is an important part of the feeding system. Because of the more important parameters, the selection of traditional parameter is mainly based on experience and look-up table failed to match the parameters accurately. This article in view of its performance parameters matching problem and the analysis of the material movement in the chute, through the kinematics and dynamics systematic research by integrating theory with practice, we can get the material conveying speed and trajectory from the simulation. The main complete results are as the following contents:(1) The force analysis and the motion analysis of the single particle movement in the vibratory chute motion are discussed in the electromagnetic vibration feeder, including the material movement form and the condition. The mathematical model of feeding speed is set up, and the influence curves of feeding speed on its factors are drawn with the MATLAB software. Through the GUI program visualization design, we can clearly see the movement form of material in the chute. Using the optimization module in the software, the theoretical parameters of conveying speed are optimized.(2) The vibration characteristic analysis of electromagnetic vibration feeder is studied, including its vibration form and isolation characteristics. The vibration model is established by analyzing its resonant characteristics. The vibration parameters are optimized and the amplitude of both upper and lower is seen as the objective function with the method of multi-objective functions. The vibration isolation parameters are optimized with the intelligent particle swarm algorithm(PSO), and the dynamic load amplitude ratio is taken as the objective function, from which we can get the reasonable kinetic parameters definitively.(3) We can get the vibration simulation model and the material movement model of single particle in the vibratory chute, when the 3 D assembly model is imported into the dynamics simulation software ADAMS. We can get the displacement curve and the amplitude-frequency characteristic curve, and simulate the trajectory of the single material movement in the vibratory chute.(4) We can get the movement simulation of material flow through the discrete element analysis software EDEM. Compare to the actual movement of materials, we simulate the feeding speed under the different parameters and the feeding uniformity. The velocity distribution and trajectory of each particle in the process of the movement are obtained ultimately.(5) The mathematical model of feeding speed is proved through the material movement analysis and the feeding form analysis with the experiment of the G type electromagnetic vibration feeder. Through the amplitude measurement of chute and base, we can validate the vibration characteristic analysis of electromagnetic vibration feeder, which demonstrates the feasibility of vibration analysis.
