Optimization Of Feeder In Offsetting Imprinter And Simulation Research

Printing industry has been developing quickly, since China joined into WTO in 2003. Improve the printing speed is the most important question should be solved as soon as possible. This paper is based on project with Shanghai Guanghua Imprinter Company to optimize the feeder in offsetting imprinter PZ4650.Feeder in offsetting imprinter is a combine of cam and four-bar linkages. This paper discusses the motion law of cam-mechanism, and then get exist cam profile via reverse engineering. UG is powerful in modeling and motion simulation, use it get the velocity and acceleration of exist mechanism. MATLAB is powerful in calculation and simulation, modeling the exist mechanism and get the velocity and acceleration, compare with the result from UG, prove the model in MATLAB is available. Then use these two powerful tools improve the profile of cam based on genetic algorithms, achieves a better result both in machine's velocity and acceleration.Finished work is followed:1. Get data of exist cam via reverse engineering, use UG/Open GRIP make the data into real cam profile.2. Finished machine modeling, assembly, and motion simulation in UG, get the velocity and acceleration data.3. Select motion low of mechanism based on the velocity and acceleration data, model this mechanism in MATLAB, get the ideal profile of exist cam.4. Model this mechanism in SimMechanics, make it the platform for Experiment.5. Learn about genetic algorithms theory and their use in mechanical design. Finished genetic algorithms program, run it, get optimized result.
