Fleksografinės spausdinimo mašinos „OMET VARYFLEX 420 FP“ sekcijos pavaros dinaminio tikslumo tyrimas / Flexographic printing press „OMET VARYFLEX 420 FP“ unit‘s drive dynamical precision research

Master‘s graduation dissertation research object is the drive of one unit of multisection web-fed flexographic printing press „Omet Varyflex 420 FP“. The main purpose of the work is drive’s dynamical precision research, basing on the torsion vibration. But the main attention is concentrated on the research object mathematical model creation. It will be able to investigate torsion vibration. In the beginning there is description of the research object, its dynamical model and assumptions, made while modeling the object. As the main research object is mechanical drive, unit’s electric drive is not detailed. Unit‘s structural model is created using the „MATLAB Simulink“ software. While modeling, it was proved the model is adequate. It was investigated how generalized coordinates and dynamical datums change while the press is switched on and starts to work with constant angular acceleration and when the angular speed reaches particular value, it does not change any more. Amplitude-frequency and phase-frequency responses of some generalized coordinates were got. Changing some parameters flexographic printing plate aging is modeled. It is watched how aging influences torsion vibration. While modeling it was determined how gearwheels cyclic harmonic error’s amplitude and beds resistance coefficients influence dynamical datums. It was also determined unit’s electric drive influence on generalized coordinates frequency responses. Basing on the analysis of the results, the conclusions... [to full text]
