Simulation analysis of screening device of tea flat circular sieving machine based on ADAMS
In order to study the screening motion characteristics of four-axis plane circular sieve machine,through UG three-dimensional modeling software system and ADAMS multi-body dynamics analysis software,the running track and load change of a four-axis plane circular sieve machine were simulated and analyzed.Through the simulation analysis results,it could be seen that the trajectory,velocity and acceleration of the centroid of the sieve bed change with time during the operation of the plane circular sieve machine.When the angle between the assembly position of the fan-shaped balance block of the plane circular sieve machine and the plane formed by the two axes of the crank was 0°,the minimum dynamic load fluctuation of the frame and the ground foundation of the plane circular sieve machine in the X-Y plane was-574.9～581.6 N,and the vibration of the frame to the ground foundation was small.With the increase of the angle between the assembly position of the fan-shaped balance block,the dynamic load fluctuation of the frame and the ground foundation also increased.When the angle of the assembly position of the fan-shaped balance block was 0°,the dynamic load on the crank fluctuated smoothly in the start-up stage and stable operation stage of the plane circular sieve machine,which was conducive to the stable operation of the plane circular sieve machine and reduced the wear of the bearing on the crank of the plane circular sieve machine.It could provide reference for the design and improvement of plane circular sieve machine.
