Description
Technical field
The utility model relates to a kind of physical arrangement stability demonstrator.
Background technology
We are in " probing into structure " this joint teaching at present, three principal elements of analyzing influence structural stability, the shape of the supporting surface size that the height of centre of gravity place, structure and earth surface are formed and structure, but at numerous theoretical Students ' very indigestibilities, the stability of structure is the critical nature of structure, is the learning foundation of structural design.How to break through this teaching difficult point, emphasis, in teaching process, teacher mostly is the principal element enumerating life example to illustrate with analyzing influence structural stability, student's great majority still indigestion, all mention triangle in most teaching and there is stability, but be difficult to again to be interpreted as what triangle and there is stability, this often will go to explain from many aspects, adds and lacks special teaching stage property, does experiment extremely lose time so will prepare stage property.
Utility model content
The technical problems to be solved in the utility model is to provide a kind ofly can simulate vibrations sight and inclination sight carries out the physical arrangement stability demonstrator tested.
For solving the problem, the utility model adopts following technical scheme:
A kind of physical arrangement stability demonstrator, comprise plastics plectane, support bar and tripod, described plastics plectane is provided with rubber bar, described rubber bar is provided with screw, described rubber bar is provided with plastic bolt, nylon cloth is provided with between described rubber bar and plastic bolt, described plastic bolt is arranged for running through nylon cloth, described plastics plectane is provided with speed-regulating switch and battery case, described battery case is embedded in plastics plectane and arranges, described rubber bar is provided with mobile phone Vib., described mobile phone Vib. and speed-regulating switch are electrically connected, described tripod is installed on support bar, described tripod and support bar clamp connection, described support bar is provided with electrical tilt instrument, described tripod is scalable setting.
As preferably, described support bar is that hollow is arranged, and weight is slim and graceful, can reduce burden when user carries, can reduce the concussion of mobile phone Vib. to the impact of electrical tilt instrument.
As preferably, described rubber bar and plastics plectane are that integral type is arranged, and good integrity, can prevent from causing rubber bar to come off because of vibrations.
As preferably, described tripod is provided with Anti-slip cover, there is good skidproof effect, vibrations can be prevented and cause tripod to be subjected to displacement.
As preferably, between described rubber bar and plastic bolt, be provided with check washer, can prevent from causing nylon cloth to come off because of vibrations during experiment.
The beneficial effects of the utility model are: by being provided with 4 rubber bars, and on rubber bar, be provided with mobile phone Vib., collocation has speed-regulating switch, vibrations sight can be simulated by starting hand-set Vib., due to each rubber bar being provided with mobile phone Vib., the effect of resonance can be formed, make vibrations more violent, test object is placed on the stability just can demonstrating often kind of physical arrangement in nylon cloth, but also the angle that can change tripod is demonstrated to the inclination conditions changing support bar.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of the utility model physical arrangement stability demonstrator.
