3D MODELING OF A PENDULUM ON A TROLLEY · 模型 101102
The structure of the considered mechanical system consists of four wheels, on which a trolley with corresponding axes and a crossbar located on it rests pivotally with the possibility of moving along a horizontal support surface. A pendulum is pivotally attached to the crossbar with the possibility of swinging. If the pendulum is withdrawn from the equilibrium position with subsequent release, the trolley and the pendulum move in antiphase relative to the common center of mass. If you install an emphasis on the horizontal support surface on the side of the rear wheels of the trolley, towards which the pendulum is withdrawn before starting movement, then when the pendulum is released, it begins a rotational movement under the influence of gravity with the trolley stationary. As soon as the pendulum reaches a vertical position, the cart begins to move and accelerates for a while. As the pendulum returns to its original angular position, the trolley begins to slow down, up to a complete stop or a slight rollback. The repeated movement of the pendulum towards the main movement of the trolley leads to a new impulse of the main movement of the trolley. In the absence of attenuation of the pendulum oscillations, the main movement of the trolley is preserved. The developed computer model can be used for virtual experiments in studying the dynamics of mechanical systems, including vibroactuators.
