Abstract
The utility model relates to a structural mechanics influence line display device, include: the truss is equipped with a plurality of slides on it, the thing piece hangs and locates on the truss and can follow the slide and slide, the display module is gathered to stress, with each nodal connection on the truss for gather the stress intensity of each node of thing piece slip in -process and show. Compared with the prior art, the utility model discloses a stress is gathered the display module and is gathered the stress intensity of each node of thing piece slip in -process and shows, and can demonstrate the structural mechanics influence line, some flexibilities are got simultaneously in developing of the teaching of being convenient for directly perceivedly, selects variously, can show the example that far is more than artifical drawing in the limited time, improvement the teaching efficiency.
Description
Technical field
The utility model relates to a kind of mechanics teaching device, especially relates to a kind of structural mechanics effect string exhibiting device.
Background technology
Structural mechanics is the important component part in engineering mechanics course, and classroom instruction link is as the important step of Students ' Learning, and the mode of teaching affects effect of teaching.Structure influence line, as the important component part in structural mechanics knowledge, plays the vital role formed a connecting link to the grasp of total mechanical knowledge.Traditional form of teaching be adopt papery or e-text, picture carries out relatively abstract description to effect string, makes student in understanding, need certain imagination, suppose even to guess and compare.And this apparatus intuitively, promptly can show the stressing influence line of various structures at diverse location, contribute to student understand rapidly as being applied to teaching, deepen the impression, permanently effective grasp knowledge.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of structural mechanics effect string exhibiting device is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of structural mechanics effect string exhibiting device, comprising:
Truss, which is provided with multiple slideway;
Thing block, is hung on truss and also can slides along slideway;
Stress gathers display module, is connected, for gathering the stress intensity of node described in thing block sliding process and being shown with at least one node on truss.
Described stress gathers display module and comprises processor, display, and multiple stress section being attached at described Nodes respectively, and the input end of described processor is connected with each stress section respectively, and output terminal is connected with display.
Described exhibiting device also comprises the bearing for placing truss.
Described bearing comprises two objective tables be oppositely arranged, and wherein at least one objective table offers the link slot for being connected truss.
Described thing block is vertical.
Compared with prior art, the utility model has the following advantages:
1) gather display module by stress gather the stress intensity of each node in thing block sliding process and shown, can display structure mechanics influence line intuitively, be convenient to carrying out of teaching, get a little flexible simultaneously, select various, can show within the limited time far more than the artificial example drawn, improve efficiency of teaching.
2) the foil gauge instantaneous acquiring being attached to each point on truss imports Mechanical Data into processor, more just each point stress state can be accumulated data form in conjunction with computing machine.
3) link slot can improve the tightness of connection.
4) vertical density is large, can amplify mechanics influence, improves and shows efficiency of teaching.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of structural mechanics effect string exhibiting device, as shown in Figure 1, comprising:
Truss 1, which is provided with multiple slideway;
Thing block 2, be hung on truss 1 and also can slide along slideway, thing block 2 is preferably vertical;
Stress gathers display module 3, is connected, for gathering the stress intensity of institute's connected node in thing block 2 sliding process and being shown with at least one node on truss 1.
Stress gathers display module 3 and comprises processor 32, display 33, and multiple stress section 31 being attached at the Nodes needing measurement respectively, the position that is sticked of stress section 31 can carry out adjustment conversion as required, the input end of processor 32 is connected with each stress section 31 respectively, and output terminal is connected with display 33.
Exhibiting device also comprises the bearing for placing truss 1, and bearing comprises two objective tables be oppositely arranged 4, and wherein at least one objective table 4 offers the link slot 41 for being connected truss 1.
The structure of truss 1 can need design according to teaching, exhibiting device specifically also comprises the different truss of multiple structure 1, choose one as required and carry out work, three simple trusses 1 are adopted in the present embodiment, and slideway is set at each section, truss one end level and smooth bearing of placing on bearing only provides vertical supporting to retrain, and truss 1 other end is placed in the link slot 41 of bearing, reach hinged object, so make truss 1 two ends hinged fixing respectively.
Under thing block 2 is hung at the pulley in slideway, by pulley mobile different nodes gravity load being applied to truss 1 in slideway.Then, as shown in Figure 4, foil gauge 31 stress that can calculate in rod member be attached in each rod member of truss imports processor 32 into.The data that user is spread out of by processor 32 carry out Screening Treatment, can go out the effect string of each measuring and calculating point by the Software on Drawing such as choice for use excel.
Meanwhile, adopt the softwares such as 3d3s before load application, carry out theory calculate, the effect string result that finally can draw two kinds of methods is compared.
