S-shaped spring pendulum

Abstract

The invention provides an s-shaped spring pendulum, belongs to the field of science and education instruments, and relates to teaching demonstration instruments. The s-shaped spring pendulum is composed of a frame, 10 to 15 springs sand 10 to 15 vibrators. The s-shaped spring pendulum is characterized in that the springs are lined up and are hung on the frame at equal intervals through rigid hanging lines, the elastic coefficients of the springs are the same, and the lengths of the springs are the same; the vibrators are respectively hung on the springs, the weights of the vibrators enable the vibration periods of the springs to be increased or decreased evenly in sequence; the lengths of the hanging lines are adjustable, and the vibrators are adjusted to be at the same height. The vibrators vibrate at the same time and in the uniform amplitude, the vibratos form various shapes, and the shapes formed by the vibrators change regularly. The elastic coefficients of the springs and the weights of the vibrators are chosen properly, and thus the s-shaped spring pendulum can return to an original position in a short time. The s-shaped spring pendulum can demonstrate interesting vibration combination phenomena and reveal mathematic regularities.

Description

Technical field [0001] The invention belongs to the field of educational instruments and relates to a teaching demonstration instrument. Background technique [0002] The serpentine pendulum is a vibration formation formed by a series of vibrators of different frequencies on the same equilibrium position line. The current serpentine pendulum is composed of several pendulum balls with different periods at the same height, which are arranged in a straight line at equal intervals. Each simple pendulum has a different period, but the adjacent simple pendulums have a constant frequency difference and swing at the same time. At this time, the relative position between the pendulum balls will change periodically. [0003] A simple pendulum with a swing angle of less than 5° can be regarded as a simple harmonic vibration, but due to the influence of factors such as air resistance, a single pendulum serpentine pendulum with a too small swing angle will soon stop swinging. In addition, sin...

Problems solved by technology

[0003] A simple pendulum with a pendulum angle less than 5° can be regarded as a simple harmonic vibration, but due to the influence of air resistance and other factors, a simple pendulum with a too small pendulum angle will soon stop swinging

In addition, since the pendulums that make up the serpentine pendulum have different pendulum lengths, it is difficult to achieve the same initial swing angle of each pendulum, and it is also difficult to achieve a better visual effect
