Abstract

The invention discloses a test device for studying the motion of a projectile under the influence of a rotating coordinate system. Relying on the centrifuge, the invention can monitor the projective motion of small steel balls with different initial velocities and directions under the conditions of different accelerations and rotational speeds, and obtain the motion of the small balls in three-dimensional space through an image recording system. The trajectory of the ball under the complex force in the rotating coordinate system is obtained, and the motion problem of the projectile moving ball under the complex force in the rotating coordinate system is solved. The operation is simple, the test results are accurate, and the advantages are outstanding. Through the experimental device of the invention, the complex projectile motion research in the rotating coordinate system can be carried out indoors, and research tools and teaching tools can be provided.

Description

technical field [0001] The invention belongs to the research field of projectile motion under the complex stress condition in a rotating coordinate system, and relates to a test device for researching projectile motion under the influence of a rotating coordinate system. Background technique [0002] In the research of projectile motion, the current teaching is basic and simple projectile motion, and only a simple calculation formula can be used to obtain its force state and trajectory, but in actual life and scientific research work, projectile That's not all there is to sports. In the static coordinate system, the projectile motion can obtain the trajectory of the object through simple calculations, but in the rotating coordinate system, the difference in the reference system will cause the projectile motion to become complicated. The earth is a huge rotating coordinate system. The projectile motion in the rotating coordinate system is not only affected by the gravitation...
