 Full text | Abstract: This article concerns the evaluation of the influence of technological loads caused by mechanism elements of a three-thread overedge sewing machine on the dynamic of its driving system concerning the cycle of steady-state motion conditions. On the basis of a physical model of such a machine with an elastic belt drive, a system of dynamic movement equations was elaborated and completed by a differential equation of the driving motor moment. The system of these equation was numerically soluted. The characteristics of the dynamic changes of forces in the particular threads, which take part in the process of creation of the stitch and are known from literature publications, were considered in the calculations. The results of a computer simulation of the sewing machine dynamic were graphically illustrated. |
