Abstract
The utility model discloses a resonance experiment instrument which comprises a suspended transverse rod, a driving ball and a plurality of driven balls, wherein the driving ball and the driven balls are respectively suspended on the transverse rod; and the driven balls are different in pendulum length; the resonance experiment instrument is characterized in that the driven balls are fixed on a swinging rod; the swinging rod penetrates through a through hole on the transverse rod to be movably connected through a fastening screw; all the plurality of driven balls are connected with suspending lines; each suspending line penetrates through a line hole and is knotted to be connected on the transverse rod; a sleeve is also sleeved on the transverse rod; bearings are arranged between the inner walls at the two ends of the sleeve and the transverse rod; and the outer wall of the sleeve is connected with the bracket. The driving ball is a metal ball; the driven balls are ping-pongs; and the bracket is of an iron frame platform. The resonance experiment instrument has the beneficial effects that as the swinging rod for fixing the driving ball is movably connected with the transverse rod, the pendulum length can be adjusted conveniently; and the relationship between the intrinsic frequency of the driven pendulum and the frequency of forced vibration is clear at a glance so as to be easy to learn.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly resonance Instrument.
Background technology
The research of resonant condition is the emphasis and the difficult point content of physics teaching in secondary school, but present experimental implementation trouble, effect is bad, is unfavorable for overcoming teaching difficulty.
The utility model content
The purpose of the utility model is: for addressing the above problem, a kind of resonance Instrument is provided.
The technical scheme that the utility model adopted is: a kind of resonance Instrument; Comprise unsettled cross bar, be suspended on the drive ball driven ball different on the cross bar respectively with several pendulum lengths; It is characterized in that: said drive ball is fixed on the fork, and said fork passes the through hole on the said cross bar and passes through trip bolt and realize flexibly connecting; All be connected with suspension wire on said several driven balls, line hole and knotting that said each suspension wire passes on the said cross bar link to each other; Going back cross-under on the said cross bar has sleeve, is provided with bearing between the inwall at said sleeve two ends and cross bar, and said sleeve outer wall links to each other with support.
Said drive ball is a metal ball, and said driven ball is a table tennis, and said support is an iron stand.
The beneficial effect of the utility model is: the fork of fixed drive ball and cross bar flexibly connect, the convenient pendulum length of regulating; The natural frequency of slave pendulum and the frequency relation of forced vibration come into plain view, and learning difficulty is low.
