Technique and hardware for the free oscillation frequency determination of modernized sawing unit arrow
Basic points of the developed technique are stated and the description of hardware and measuring fasilities for determination of oscillation frequency of modernized sawing unit arrow is provided. The sequence of measurements for determination of the free oscillation frequency of the arrow, and also coefficient of rigidity of elastic subweight is described. On the basis of experimentally evaluated values of the free oscillation frequency of the arrow and coefficient of rigidity of its subweight parameters of excitement of oscillatory system are established. These parameters includs the forced oscillation frequency and amplitude which provide an underresonfnt mode of the system performance.
