IMPROVING THE EFFICIENCY OF THE TWO-STAGE MECHANICAL OSCILLATOR BY USING CERAMIC BALL BEARINGS OR ELASTIC (FLEXIBLE) PENDULUM
Veljko Milkovic demonstrates ways how to make a two-stage oscillator model more efficient.
Based on all independent scientific papers published so far, as well as videos of replicas of the two-stage mechanical oscillator that can be found on the Internet, it is noted that all these mechanisms are constructed using steel ball bearings.
These steel ball bearings are a hidden brake, which is harmful during operation because it reduces the inertia and thus the efficiency of the entire device (this is a harmful phenomenon in the case of oscillations, but not in the case of rotations as well). Therefore, it is recommended to all researchers and engineers around the world to use ceramic ball bearings and an elastic (flexible) pendulum to obtain significantly less friction.
According to their characteristics, ceramic ball bearings have a lower coefficient of friction. In addition, ceramic balls are lighter than steel balls, resulting in less inertia which further improves their efficiency. Adequate selection of ball bearings can significantly increase the efficiency of the oscillator in terms of the duration of oscillations during laboratory or practical tests. This improvement is achieved precisely by reducing friction and inertia, which results in a longer duration of oscillations, thus greater efficiency and lower energy consumption for their maintenance (e.g. in case of maintaining the pendulum oscillation).Ball bearings are eliminated in the elastic (flexible) pendulum design, therefore less energy is lost in ball inertia and friction, resulting in even greater efficiency.
The two-stage mechanical oscillator and its practical application have been studied all over the world in university centers, institutes and by enthusiasts for 20 years; with 2 doctoral theses (Ph.D. dissertations) published so far [the third one in the final stage], 39 scientific research papers, 5 university graduate theses, 5 papers from different scientific conferences, as well as 10 other papers related to this invention.
