Özet
ı p ı p ı p ı p ı p Figure 6. Tension of yarn By the geometry at figure 5 and 6;.(p = 3.14-(Pn., +pn) P = Arctan[c/(an +bj] By using the computer programe; six unknown reaction forces have been calculated. Numerical analysis have been done for the machine revolutions as 6, 8, 12, 16, 22 rpm and by assuming the sinker mass as 0.794 gr., 1 gr., 1.2 gr. and for the coefficient of friction (metal to metal) as 0.1, 0.12 and 0.14 During the experimental work; the micro miniature strain gauge has been placed on sinker. Thus; vertical and horizantal strain has been measured. In the graphs emanating from the studis; there are almost constant line and vibration lines and the peaks. Almost constant line comes from pre-strain on the sinker due to cable exct. which is not because of relanit motion of sinker,the peaks comes from sudden change without control on the motion between 4 and 5 region because of the transient cam profile, vibration lines come from relanit motion which sinker moves down and up and as rocking and also some of them from environmental noise. Direction of all reaction forces changes during knitting cycle and the maximum value of P, Q reaction forces always are higher than R5 S, W, N. The mathematical equation of motion is very important for the results. Because; while changing of velocity, mass and coefficient of friction effect the results some, changing of equation of cam profile effects the results more. And also reaction forces contain variable cam angle, acceleration of sinker exct... which depend on the mathematical equation of motion at cam profile. xix

By utilizing the results of this study by the use of a suitable cam profile which produces the low intensity and almost stable force, the possibility damage to the machine can be decreased while machine revolutions and thus, machine production are increased. xxı p ı p ı p ı p ı p Figure 6.
