The mathematical model for evaluating the dynamic behavior of linear vibratory feeders is presented and discussed. The model is based on the Eksergian's equation of motion, Secondly, by calculating the centrifugal force of the eccentric rotor, the vibration of the relative phase of the rotor position, and the width of the air gap between the rotor and the Machines Free Full-Text Active Control Method for Rotor Eccentric

A vibration exciter is a machine which produces mechanical vibratory motion to which the test object is subjected. This article presents design, construction, performance and testing of mechanical vibrations exciter, which have unbalanced mass to generate of rotating eccentric mass. The vibrations produced lie in the low frequency ANCO Structural Eccentric Mass Vibrators Most vibrators are driven by variable speed electric motors. The size of the motor will depend on the size of the vibrator (internal friction, windage) and the amplitude of the motion achieved on the structure being tested.

The rotating eccentric weights vibrator system of this invention is comprised of a base and a rotating rectangular frame having mounted upon it eccentric weights which rotate in synchrony. The base has two arms which extend upright, and a rotating rectangular frame is supported by the arms and rotates about an axis located at about the middleUS11052426B2 US16/279,838 US201916279838A US11052426B2 US 11052426 B2 US11052426 B2 US 11052426B2 US 201916279838 A US201916279838 A US 201916279838A US 11052426 B2 US11052426 B2Eccentric vibrator systems and methods Google Patents

Typically we see two different types of eccentric masses on ERMs: Offset Disc Simply a cylinder with a hole for the shaft, which is offset from the centre of the disc. This creates an eccentricity which in turn produces the vibration when rotating about the shaft.

Mechanism. Let’s describe the mechanism using the biceps brachii muscle (forearm flexor) as an example. During concentric contraction, the biceps shortens and pulls the weight towards the shoulder joint.. Two situations can lead to an eccentric movement from this point;. The biceps is loaded with a force greater than the one it produced during
