Abstract

The invention relates to a tuning fork vibration chaotic experiment table which is characterized in that a U-shaped tuning fork is horizontally arranged on a platform, the rear end of the tuning fork is fixedly arranged on the platform, and the front end thereof is suspended; an electromagnet fixedly arranged on the platform is positioned between two tuning fork pieces of the U-shaped tuning fork, and gaps are reserved between the electromagnet and the inner side walls of the two tuning fork pieces; a vibration piece is arranged at the front end of a tuning fork piece along a tuning fork piece in a suspending way; a current vortex sensor probe is arranged on one side at the front end part of the vibration piece and fixed on the platform, and a gap is reserved between the current vortex sensor probe and the vibration piece; and a chord line which is horizontally arranged is fixedly connected with the front end of the vibration piece, and a weight is suspended at the other end of the chord line through a dead pulley. By adopting the tuning fork vibration chaotic experiment table, the chaos phenomenon generated by a nonlinear vibration can be intuitively observed, and the chaotic motion can be quantificationally researched.

Description

technical field [0001] The invention relates to an experiment device, more specifically a tuning fork vibration chaos experiment platform for studying chaos phenomena, which can be used as an instrument, a teaching experiment instrument, and a physical experiment instrument. Background technique [0002] In recent years, the research of nonlinear science has developed vigorously, which reveals the limitations of determinism in classical physics and the deficiency of stochastic theory in modern physics. As a branch of modern science, nonlinear science, like quantum mechanics and relativity, will bring new ideas and astonishing results to people. The development of nonlinear science has announced the limitations of classical theoretical determinism, and at the same time revealed the shortcomings of modern physics such as statistical physics and random theory of quantum physics. The most important branch and one of the most typical phenomena in nonlinear science is chaos, whic...
