  This paper aims at the teaching contents of "Fluctuation and Regulation in
Speed of Machines" for students, explores the effect of the flywheel on the
speed regulation of the mechanism system and its influencing factors, designs
an experimental device with applied value, and develops a comparatively
complete experimental scheme by contrasting experimental principles. Using this
experimental device, we can in-depth study of the effect of the flywheel on the
speed of different drive shafts, and deepen students' understanding and mastery
of knowledge about regulation in speed.
