Abstract
The utility model provides an analysis device for discussing and teaching general mechanics, and belongs to the field of teaching devices. The analysis device structurally comprises a magnetic adherable blackboard, a velocity arrow magnetic sticker, an acceleration arrow magnetic sticker, a force arrow magnetic sticker, an angular velocity arrow magnetic sticker, an angular acceleration arrow magnetic sticker and a couple arrow magnetic sticker, wherein the magnetic stickers are used with the magnetic adherable blackboard, the velocity arrow magnetic sticker, the acceleration arrow magnetic sticker and the force arrow magnetic sticker are straight line arrows, and the angular velocity arrow magnetic sticker, the angular acceleration arrow magnetic sticker and the couple arrow magnetic sticker are arc arrows including anticlockwise arrows and clockwise arrows. The analysis device has the advantages of reasonable design, simple structure, portability, convenience in use and the like, can run through analysis, discussion and teaching of the whole statics, kinematics and dynamics, greatly reduces the workload of drawing, and can be used for analyzing velocity, acceleration and stress.
Description
(1) technical field
The utility model relates to a kind of instructional device, and analytical equipment is used in a kind of investigation of General Mechanics and teaching specifically.
(2) background technology
In the investigation and teaching of General Mechanics such as theoretical mechanics, analytical mechanics, must draw a large amount of arrows and decompose motion conditions and stressing conditions with object analysis.In this process; Teacher or symposial host must draw a large amount of arrows to show each item analytic process clearly; Not only workload is very big, takies the time on the valuable class, and tends to cause arrow to be superimposed; The confusion of vision and thinking exchanges or Teaching Quality thereby influence easily.
(3) summary of the invention
The technical assignment of the utility model is the deficiency to prior art, provides a kind of investigation and teaching of playing the General Mechanics of optimizing drawing, assistant analysis to use analytical equipment.
The utility model solves the technical scheme that its technical matters adopted:
Analytical equipment is used in the investigation of General Mechanics and teaching; But comprise the blackboard that magnetic attaches, but said device comprises that also the speed arrow magnetic that the blackboard that attaches with magnetic is used pastes, acceleration arrow magnetic pastes, power arrow magnetic pastes, angular velocity arrow magnetic pastes, angular acceleration arrow magnetic pastes, couple arrow magnetic pastes.
Said speed arrow magnetic pastes, acceleration arrow magnetic pastes, power arrow magnetic pastes and is straight arrows, can adopt different colours or on arrow, mark the corresponding mechanics standard label and distinguish.
Said angular velocity arrow magnetic pastes, angular acceleration arrow magnetic pastes, couple arrow magnetic pastes and is the camber line arrow, can adopt different colours or on arrow, mark the corresponding mechanics standard label and distinguish.
Said camber line arrow had both comprised anticlockwise arrow, also comprised clockwise arrow.
The investigation of the General Mechanics of the utility model and the teaching with analytical equipment compared with prior art, the beneficial effect that is produced is:
1) the utility model is reasonable in design, simple in structure; Carry with easy to use; Can in whole statics, kinematics, analysis of dynamics investigation and teaching, reduce the workload of drawing greatly, can be used for carrying out velocity analysis, acceleration analysis, force analysis work.
2) the utility model can be put arbitrarily, recycles environmental protection.
