Abstract
Non-ideal systems have been largely studied in the literature and are still challenging research in the field of engineering due to their intrinsic complexity. In such systems, the dynamics of the structures influence the power source, which can be a motor. This interaction can cause the motor to stall and not give the specified speed at a certain power input, since, unlike ideal energy sources, the power supply is limited (called nonideal -RNIS). Different phenomena arise when there is a strong interaction between the system and the energy source, such as the resonance capture phenomena, also known in the literature as the Sommerfeld effect. In this work, the object of study is a conveyor belt system, which can be found in sugar and alcohol plants, responsible for maintaining a constant feed for the mill. For this, numerical simulations were performed using a simplified mathematical model, which consists of a rigid body representing the conveyor belt and four springs representing the columns that support it. An unbalanced direct current motor (of limited power supply (RNIS) was coupled to the conveyor belt to perform the function of a non-ideal energy source. An experimental analysis was also developed using IoT (internet of things) equipment, with the aim of comparing the conclusions obtained between the two methods (experimental and numerical).
