ABSTRACT This paper presents a theoretical analysis of the working dynamics of the pendulum-lever oscillatory system, which its inventor called a two-stage mechanical oscillator [1]. The input of the system is a pendulum, while the output of the system is a lever that can idle like a hammer or deliver power to a water pump. It is shown that the transfer of energy from the input to the output of the system represents the damped operating mode of the parametric oscillator [2]. Namely, the oscillation of the lever moves the pivot point of the pendulum up and down in such a way that it takes away energy from the pendulum. This way of working is the opposite of the way a child swings a swing [3]. In this article, the forces acting on the driving pendulum are presented, and the focus of the paper is on the analysis of the change in centrifugal force as a reaction to the main component of the tension force in the pendulum rod. Since the tension force of the pendulum transfers its energy to the lever, it is necessary to prevent the rapid transfer of energy so that the pendulum does not stop, and on the other hand to ensure that the transferred energy has sufficient power for the lever to perform work. |
