Multifunctional rotating disc type coupling pendulum experimental instrument

Abstract

The invention discloses a multifunctional rotating disc type coupling pendulum experimental instrument. The instrument comprises a rack, a guide rail, an upper cross beam, a stepping motor, an upper angle encoder, an upper angle encoder fixing frame, an upper volute spiral spring, an upper rotating disc, a lower rotating disc, a lower volute spiral spring, a lower cross beam and a lower angle encoder, the inner connecting end of the upper volute spiral spring is connected with the upper clamping rod shaft, the outer connecting end of the upper volute spiral spring is connected with the upper clamping rod, the inner connecting end of the lower volute spiral spring is connected with the lower clamping rod shaft, and the outer connecting end of the lower volute spiral spring is connected withthe lower clamping rod. The beneficial effects are that in the aspect of liquid coupling, the instrument has remarkable advantages, is suitable for transparent and non-transparent liquid, simple andeasy to operate and capable of saving more liquid, the distance between the two discs is easy to adjust, disassembly is easy, cleaning is convenient, and real-time data display is achieved through computer program processing; in the aspect of magnet coupling, the instrument does not need complex adjustment and can be used after the magnet is well fixed.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, and in particular relates to a multifunctional rotating disc coupling pendulum experimental instrument. Background technique [0002] Since Huygens discovered the synchronization phenomenon of wall clocks, the study of various coupled vibration forms and the construction of various coupled pendulums have become a long-term research focus in classical mechanics. In previous studies on coupled motion, the coupling method generally used spring coupling. In recent years, there have also been coupled pendulums using magnet coupling. This has produced interesting experimental phenomena. There is still a lot of work to be done on magnet coupling. At the same time, it should be emphasized that there is no report on the use of liquid to achieve coupled motion. According to the above research status, this paper proposes a multifunctional rotating disc coupled pendulum experimental instrum...
