Purpose of the work . Establishing the patterns of a flexible belt movement on a drive pulley, to determine the parameters of power and kinematic interaction of the belt with the drive pulley, taking into account mechanical characteristics of the drive, belt and their contact interaction. Method of the work. Computer simulation of belt movement on the drive pulley as a multi-body system using the Universal Mechanism software package. Results. A computer-based multi-body model of the belt movement on the drive pulley has been developed. The model allows determining the parameters of the force and kinematic interaction of the belt with drive pulleys taking into account the viscoelastic properties of the belt, the nonlinear dependence of the friction force on the sliding speed and the elasticity of the contacting surfaces. The model includes a closed belt covering the drive and brake pulleys. The belt represented by 36 discrete bodies connected by elastic-dissipative elements. The computer model was verified using theoretical dependences. A technique for analyzing the belt movement on the drive pulley is demonstrated. The computer model and methodology are intended to analyze the operation of friction belt drives, belt conveyors, belt grinding machines in the design of woodworking equipment.
