COMPUTATIONAL DYNAMIC ANALYSIS OF SINGLE-MASSFREELY SHAKING CONVEYERS WITH CENTRIFUGALVIBRATION EXCITER

摘要

Single-mass freely shaking (vibrational) conveyers with a centrifugalvibration exciter transmit their load based on the jumping method. The trough isoscillated by a common unbalanced-mass driver. This vibration causes the loadto move forward and upward. The moving loads jump periodically and moveforward with relatively small vibration. The movement is strictly related tothe vibrational parameters. This is applicable in laboratory conditions in theindustry that accommodate a few grams of loads, up to those that accommodatetons of loading capacity. In this study, the variation of motional parameters hasbeen represented graphically using the software Mathematica with respect toi) vibrational parameters, ii) parameter of the unbalanced mass, iii) operationmode, iv) friction coefficient, and v) angle of attack. The proper parameters forthe transport of the numerous loads and the transportation velocity can bechosen with the help of the graphics. The results obtained in this study have beencompared with the experimental results in the pertaining literature, and havebeen found to be well matched.
