Device and method for measuring actual acceleration of free falling body under rotating coordinate system

Abstract

The invention discloses a device and a method for measuring the actual acceleration of a free falling body under a rotating coordinate system. The test device mainly comprises a centrifugal machine, an outer box, a middle frame, a free falling body device, an image recording device and the like. According to the invention, based on the centrifugal machine, the acceleration of the freely falling small ball at different heights in the rotating coordinate system can be monitored, the motion trail of the small ball in the three-dimensional space is acquired through the image recording system, and the motion equation of the small ball under the condition of complex stress is obtained by manually controlling the parameters of the rotating coordinate system. The method solves the problem of actual acceleration measurement of the free-falling small ball in the rotating coordinate system, and is simple to operate, accurate in test result and outstanding in advantage. The experimental device can measure the acceleration of the motion of the free falling body under a rotating coordinate system indoors, and a research tool and a measurement tool are provided.

Description

technical field [0001] The invention belongs to the research field of free-fall motion under complex stress conditions in a rotating coordinate system, and relates to a measuring device and method for the actual acceleration of a free-falling body in a rotating coordinate system. Background technique [0002] In the research of free fall motion, most of them are basic and simple free fall motion in a single coordinate system, and only a simple calculation formula can be used to obtain its force state and motion trajectory, but in astrophysics research and scientific research work, The coordinate system of object motion is not static, and the simple free-fall motion calculation method cannot meet the needs of scientific research. In a single coordinate system, by determining the initial velocity direction and acceleration of a free-falling body, the trajectory of the object can be calculated by Newton's law; but in the rotating coordinate system, as the object moves, its acce...
