7 results about "Conical pendulum" patented technology

A conical pendulum consists of a weight (or bob) fixed on the end of a string or rod suspended from a pivot. Its construction is similar to an ordinary pendulum; however, instead of swinging back and forth, the bob of a conical pendulum moves at a constant speed in a circle with the string (or rod) tracing out a cone. The conical pendulum was first studied by the English scientist Robert Hooke around 1660 as a model for the orbital motion of planets. In 1673 Dutch scientist Christiaan Huygens calculated its period, using his new concept of centrifugal force in his book Horologium Oscillatorium. Later it was used as the timekeeping element in a few mechanical clocks and other clockwork timing devices.

Conical pendulum demonstrator

ActiveCN224096293UEducational modelsElectric machineryConical pendulum
The utility model discloses a conical pendulum demonstrator which comprises a base, a vertical rod and a swinging ball, a first motor is arranged in the base, the driving end of the first motor is fixedly connected with the vertical rod, the swinging ball connected through a flexible connecting piece is fixed at the upper end of the vertical rod, two clamping plates are oppositely arranged on the two sides of the vertical rod, and the swinging ball and the flexible connecting piece are located in a gap between the two clamping plates. The swing ball can rotate along with the vertical rod along the fixed point to be centrifugally lifted, when the vertical rod of the conical pendulum demonstrator is driven by the first motor to rotate, the flexible connecting piece connected to the vertical rod drives the swing ball to rotate along with the vertical rod to be centrifugally lifted, and the conical pendulum demonstrator is compact in design structure, small in size and convenient to move and operate; the arrangement of the clamping plates enables the phase angle of the swing ball to be fast synchronous with the rotating speed of the vertical rod, enables the conical pendulum to move fast and to be in a stable state, prevents the phase angle of the swing ball from lagging behind the rotating speed of the rotating vertical rod for a long time after the start of rotation, and improves the use efficiency.
