Dynamic Analysis And Optimization Design Of A New Type Of Vibrating Feeder

Vibrating feeder has a history of many years,with the continuous development of technology,vibrating feeder plays an increasingly important role in the material transportation industry,with cost-effective,simple to use,stable work and many other advantages,in the electronics,hardware,pharmaceutical,food and other industries have been widely used.The common feeders on the market are linear electromagnetic vibrating feeder and spiral electromagnetic vibrating feeder in two forms,linear feeder can be used for directional finishing materials,spiral feeder can be sorted materials,but they can only transport materials along a certain direction due to the constraints of the design concept.As the industry continues to grow,more and more lines are requiring devices that can transport material in multiple directions,and there is a lack of research into devices that transport material in multiple directions.Production lines are still using traditional vibratory feeders in combination with other devices to disperse parts.Therefore,this paper will design and develop a feeder system that can transport materials in multiple directions,through the mechanical subsystem and control subsystem to work together,and finally achieve the function of multi-directional transport of materials to meet the needs of the production line,with high practical value.The main work accomplished in this paper is as follows:(1)Based on the working principle of near-resonant feeder,a new structure of feeder is proposed based on the traditional linear vibrating feeder structure using the decoupling principle.The kinetic analysis of the general motion of the elastically supported rigid body in space is combined with the base point method,and the kinetic equations of the new feeder are determined by combining with the actual structure of the feeder.All parameters of the kinetic equations are determined by searching relevant design manuals and empirical formulas.The analytical solutions are solved for each order of intrinsic frequency and corresponding intrinsic vibration mode as well as for steady-state vibration.Based on the theoretical modeling,the theoretical analysis and the possible errors in the physical object,modal tests and simulations with different software are performed to verify the correctness of the theoretical analysis and modal parameters.(2)Combining the force analysis of the material in the material tray with the analytical solution of the steady-state vibration of the new feeder,the sliding motion and throwing motion of the material that can play the effect of transportation are analyzed,the overall form of the material motion and the motion parameters are determined,and the physical assembly of the mechanical parts is carried out.(3)Derive the control method for the directional angle of material movement by means of displacement and voltage equations and verify its correctness using ADAMS software.The design of the control system is proposed and each part of the scheme is introduced,the program is written to design the human-machine interface,the type of vibration feeding controller chosen is determined and some of its functions are described in detail,the core program of the control system is written and the control system is built.Finally,the whole new vibratory feeding system will be tested for feeding.
