 Dynamic behavior of essentially new log processing equipment – cranked multirip bench with circular translational movement of saw blades was researched. Mathematical models for core element of the bench (saw module) and for system as a whole were created. Motion stability of saw module is analyzed using Floquet-Lyapunov’s method and qualitative research techniques are used for whole system’s motion analysis. The author studied design factors influence on the core element behavior and system as a whole. The author discovered that though the core element (saw module) has nonlinear behavior and certain unstable modes, the system as a whole consisting of six core elements displays mostly linear behavior and is independent of neither the rotation angle nor the angular velocity of drive shaft. The results obtained in this work are included in the author’s methodology for efficient design of essentially new log processing equipment.
