Description
Technical field
The invention belongs to the Basic Mechanics Experiment teaching field.
Background technology
Experimental teaching is the important component part of higher education, and the talent who cultivation is had higher overall qualities plays the irreplaceable effect of other links.The target of Reform of Experiment Teaching is exactly to make the student can better grasp basic skills and the technical ability of experimental study, has the ability of independently carrying out experimental study, possesses the basic quality of expanding to association area.Therefore, exploitation and the popularization of comprehensive designability experiment are inexorable trends.By the character integrated use knowledge of student according to problem, the designed, designed experimental program is drafted the concrete steps of experimental program, comprises the design of the hardware and software relevant with experiment.Study by experiment the Mechanics Phenomenon that occurring in nature is difficult for observing directly, further grasp mechanical concept and theory of mechanics, make the student to practise in experimental middle school, study in experiment.
Summary of the invention
The objective of the invention is for carrying out the Basic Mechanics Experiment of comprehensive designability and research, propose a kind ofly can realize the comprehensive tensile test device of multiple Basic Mechanics Experiment by autonomous Design, combination.
The present invention adopts following technical scheme for achieving the above object:
A kind of combined type tensile test device, comprise that rectangle frame posture experiment table, mechanical type handwheel charger, power sensor and dynamometer, upper pull head, lower pull head, test specimen, joint arrangement, described mechanical type handwheel charger are arranged on the back timber of rectangle frame posture experiment table, the below of mechanical type handwheel charger connects strong sensor and dynamometer, described upper pull head is connected with test specimen with power sensor and dynamometer respectively, described lower pull head is connected with joint arrangement with test specimen respectively, and described joint arrangement is fixed on the bottom girder of rectangle frame posture experiment table.
Described in the present invention, upper pull head is connected with test specimen with power sensor and dynamometer by pin respectively, and described lower pull head also is connected with joint arrangement with test specimen by pin respectively.
Beneficial effect: this experimental provision simple structure, dexterous attractive in appearance.Can realize to test specimen stretch to the heart, can realize axial tension or axial compression experiment to multiple different structure form by changing the up and down pull head.
Description of drawings
Fig. 1 is the general arrangement of stretching device.
Embodiment
a kind of combined type tensile test device, be provided with a rectangle frame posture experiment table, mechanical type handwheel charger 3, power sensor and dynamometer 4, upper pull head 5-1, lower pull head 5-2, test specimen 6, joint arrangement 7, mechanical type handwheel charger 3 is arranged on the back timber 2 of rectangle frame posture experiment table, the below of mechanical type handwheel charger 3 connects strong sensor and dynamometer 4, upper pull head 5-1 is connected with test specimen 6 with power sensor and dynamometer 4 respectively, lower pull head 5-2 is connected with joint arrangement with test specimen 6 respectively and is connected, joint arrangement 7 is fixed on the bottom girder 1 of rectangle frame posture experiment table.Upper pull head 5-1 in the present invention is connected with test specimen 6 with power sensor and dynamometer 4 by pin respectively, and lower pull head 5-2 also is connected with joint arrangement with test specimen 6 by pin respectively and is connected.
When carrying out one way tensile test by the combined type tensile test device, at first need upper pull head 5-1, lower pull head 5-2 and test specimen 6 use pins 8 are coupled together, then by the mechanical type handwheel charger 3 on upper pull head 5-1 connection experiment table back timber 2, lower pull head 5-2 universal-joint device 7 also is fixed on experiment table bottom girder 1, wherein joint arrangement 7 has any direction degree of freedom in the plane, can guarantee to stretch to the heart, can test according to the experimental design scheme afterwards.The present invention can realize multiple multi-form member is carried out axial tension or axial compression experiment by the different upper pull head 5-1 of conversion, lower pull head 5-2.Joint arrangement 7 of the present invention is fixed on the bottom girder 1 of rectangle frame posture experiment table, has any direction degree of freedom in the plane, in order to guarantee to stretch to the heart.
This combined type tensile test device is a kind of in the desk type multifunctional combined experimental device of developing for the material mechanics experiment of carrying out comprehensive designability.And Multifunction composite experiment device can carry out slow test and the one way tensile test of the comprehensive designability experiment of the rigid frame of multiple different structure form, different constraint types, truss, can realize independently building rigid frame and the truss of various ways, utilize multiple bearing to form multi-form constraint, can realize applying simultaneously single or multiple load on different load(ing) points with assembling rod member, and can realize that asymmetrical load and antisymmetry load, but the student is flexible design, autonomous enforcement in experiment, can cultivate student's autonomous innovation and put into practice manipulative ability.
Most domestic Basic Mechanics Experiment device is all simple function basically at present, can only realize a kind of experiment on an experimental provision.The part combined experimental device is also arranged, and is that several fixing basic experiment are assembled on a device jointly.And the difference of this multifunction combined dynamics experimental device maximum just is its composability and polytrope, the student can be according to the needs of autonomous Design experiment, select required rod member, joint, constraint bearing and load mode and load(ing) point, independently make up kinds of experiments, so just realized very easily the multifunctionality of device, simultaneously can also deepen the student to the understanding of Experiments of Machanics, consolidate and improve the mechanical knowledge of learning.Excite innovative thinking by the design synthesis experiment, effectively improve theory and practice in conjunction with operational capability, and grasp knowwhy be used in skill in the middle of practice.
