Pendulum motor with self-oscillations

grabcad

An educational mockup of a pendulum vibromotor with auto-oscillations, in which a scheme from the video https://www.youtube.com/watch?v=tAypB6GXOaY is taken as the basis. The peculiarity of the drive of the pendulum-type vibromotor is the fact that the pendulum accelerates and operates in self-oscillation mode. In this case, the work of the vibromotor is simulated during its movement in the forward (Моделирование работы.wmv) and reverse (Моделирование работыR.wmv) directions with the corresponding directions of rotation of the drive shaft. Each case of the direction of motion of the vibromotor is modeled in two files: acceleration of the drive shaft and the pendulum with a fixed platform of the vibromotor (files И1о-Моделирование работыR_.grb and И2о-Моделирование работыR_.grb), as well as directional movement of the vibromotive, including acceleration and displacement after acceleration (И1к-Моделирование работыR_.grb and И2к-Моделирование работыR_.grb). After acceleration, the vibromotor platform has the possibility of free movement in the horizontal plane (during the acceleration period, the platform is stationary relative to the horizontal plane). In models that demonstrate the operation of a vibromotor, friction is taken into account (И1к-Моделирование работыR_.grb and И2к-Моделирование работыR_.grb), or friction is taken into account only when the pendulum and shaft contacts the discs - to maintain the self-oscillating mode of the pendulum drive (И1к3.grb and И2к3.grb), the remaining hinges in the model are modeled without friction - as ideal.
