Abstract
The utility model discloses an experimental apparatus of self-adaptation structure teaching, this experimental apparatus of self-adaptation structure teaching includes: frame, outer frame, inside casing, rope, pulley. The utility model discloses a place counter weight iron plate at the frame, then change the inside casing counter weight again, frame and inside casing can reach the balance in the position of difference always, because the frame counter weight is a definite value, if do not consider the frictional force of pulley, the pulling force of rope also is the definite value, and the system is not through changing power promptly, but keeps balance through changing the shape, has realized the structural system of self-regulation and self-protection. When the load increases, the shape of the structure can be changed greatly while the internal force is maintained substantially unchanged. The utility model enables students to vividly show the characteristics of the self-adaptive structure through the condition that the loading observation system changes along with the load, stimulates the learning interest of the students and explores the principle of the self-adaptive structure; the experimental device is simple and convenient to install, and can cultivate the practical ability of students.
Description
Technical field
The utility model belongs to technical field of teaching instruments, relates in particular to a kind of experimental provision of adaptive structure teaching.
Background technology
College freshmen is often full of curiosity for learned specialty at the beginning of admission, but now they still do not possess the basis of direct study specialized courses, by carrying out simple Experiment Introduction ultimate principle wherein, be answer student's puzzlement, excite a kind of effective approach of professional interest.
Yet often price is high for existing Specialty Experiment device, and must possesses certain professional skill and could operate, this just causes allowing the rehearsal of students of the junior years' all operations were both unrealistic, more cannot guarantee teaching efficiency.
Utility model content
The purpose of this utility model is to provide a kind of experimental provision of adaptive structure teaching, is intended to solve that the price that existing experimental provision exists is high, the problem of complicated operation.
The utility model is achieved in that a kind of experimental provision of adaptive structure teaching, and the experimental provision of this adaptive structure teaching comprises: framework, housing, inside casing, rope, pulley;
Framework is arranged on the outermost of experimental provision, and housing is arranged on the bottom of framework, and inside casing is arranged on the top of framework, and housing connects inside casing, and pulley is arranged on the top of framework, and rope is arranged on pulley.
Further, pulley provides pulley groove to be arranged on the top of framework.
Further, housing provides the rope on pulley to connect inside casing.
The experimental provision of the adaptive structure teaching that the utility model provides; by placing counterweight iron block at housing; and then change inside casing counterweight; housing and inside casing can reach balance in different positions, because housing counterweight is certain value, if do not consider the friction force of pulley; the pulling force of rope is also definite value; be that system is not by change power, but keep balance by changing shape, realized the structural system of self-control and self-protection.When load increases, can there is very large change in the shape of structure and internal force remains unchanged substantially.The utility model makes student by loading observe system with the situation of loads change, shows visually the feature of adaptive structure, excites students ' interest of study, explores wherein principle; Experimental provision is installed simple and convenient, the manipulative ability that can cultivate student.In addition, the utility model new in structure, simple to operate, is convenient to students principle, has reduced the cost of teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the experimental provision of the adaptive structure teaching that provides of the utility model embodiment;
In figure: 1, framework; 2, pulley; 3, rope; 4, housing; 5, inside casing.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The experimental provision structure that the adaptive structure that Fig. 1 shows the utility model embodiment to be provided is imparted knowledge to students.For convenience of explanation, only show the part relevant to the utility model.
The experimental provision of the adaptive structure teaching of the utility model embodiment, the experimental provision of this adaptive structure teaching comprises: framework, housing, inside casing, rope, pulley;
Framework is arranged on the outermost of experimental provision, and housing is arranged on the bottom of framework, and inside casing is arranged on the top of framework, and housing connects inside casing, and pulley is arranged on the top of framework, and rope is arranged on pulley.
As a prioritization scheme of the utility model embodiment, pulley provides pulley groove to be arranged on the top of framework.
As a prioritization scheme of the utility model embodiment, housing provides the rope on pulley to connect inside casing.
Below in conjunction with drawings and the specific embodiments, application principle of the present utility model is further described.
As shown in Figure 1, the experimental provision of the adaptive structure of the utility model embodiment teaching is mainly comprised of framework 1, housing 4, inside casing 5, rope 3, pulley 2; The upper position of framework 1 is provided with pulley groove, and pulley is installed in pulley groove, and framework 1 inside is provided with inside casing 5 and housing 4, and rope 3 is connected with housing 4 with inside casing 5 respectively by pulley 2, forms fixed pulley system;
Principle of work of the present utility model:
As shown in Figure 1, during experiment, first at housing 4, place counterweight iron block, and then the counterweight of change inside casing 5, housing 4 and inside casing 5 can reach balance in different positions, because housing counterweight is certain value, if do not consider the friction force of pulley 3, the pulling force of rope 3 is also definite value, and system is not by change power, but keeps balance by changing shape.
The utility model is simple in structure, easy to operate, and cost of manufacture is low, for teaching provides the instrument that cost performance is higher.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
