Electromechanical model of a hedge trimmer mechanism

Absztrakt

Hedge trimmers are used for various applications, from lighter vegetations to tree-like plants. A key component of the hedge trimmer is the eccentric disk within its drive train, that can be looked at as a cam-follower mechanism. The eccentric is responsible for transforming the rotating motion into an alternating one. Another important thing about the eccentric is the acceleration it generates during the operation for the blades, this acceleration must be considered when considering the cutting force. With different eccentric profiles different acceleration can be achieved. This paper aims to create an electromechanical model for the drive train of a hedge trimmer and to examine the behavior of the system based on its variables.
