Abstract
The invention discloses a Zhang Heng seismograph internal structure and a vibration measuring principle. A horizontal component of vibration displacement, caused by an earthquake or other reasons enables overhanging pendulum bodies and inverted pendulum bodies of "a central copper column" and "eight channels" to be arranged through leaning, i.e., a level combination which is formed through "leaning" coupling, has a power arm smaller than a resistance arm and has a composite lever feature generates inertia swing along eight limited directions, and the displacement is amplified for thousands of times while vibration is transmitted. One side with maximum swing, first of all, triggers hook-shaped parts of clamping mechanisms which realizing "head cohesion of copper balls" and "machine-triggered ball throwing", and at the same time, a restraint apparatus "ingenious brake" ensuring that "other seven drain heads maintain still while one dragon is triggered" is closed. The Zhang Heng seismograph internal structure "is tested by facts and is accurate as if it is predicted by god" and has a function of detecting micro vibration "which is not felt on the ground", and is clearly embodied in such historical descriptions as "an upper portion and a lower portion are closed and covered, " the upper portion and the lower portion are covered tightly without any slits", " in case of ground shock, a dragon on a goblet body vibrates" and the like, and can be applied to teaching, research and display in multiple aspects relating to history, Chinese, physics and the like.
