Description
Technical field
The present invention relates to a kind of experiment table, especially comprehensive vibration test table.
Background technology
At present, vibration experiment table is mainly single cantilever beam structure, simple beam structure, the vibration testing device of the vibration testing device of unitized construction or overhanging beam and free beam textural association, these vibration testing devices can only be done vibration experiments a kind of or two kinds of structures, therefore, when need to do the vibration experiment of cantilever beam structure simultaneously, when the vibration experiment of simple beam structure and the vibration experiment of unitized construction, many vibration experiment equipment need to be purchased and request for utilization could be met, purchase many vibration experiment equipment and not only need to spend more funds, also can take the space in laboratory simultaneously.
The < < laboratory study that applicant published in June, 2010 with explore > > the 6th phase magazine in delivered the article of the development > > of one piece of < < mechanical kinetics comprehensive vibration test table, a kind of comprehensive vibration test table that can do the vibration experiment of linkage assembly in unitized construction is disclosed in this article, this comprehensive vibration test table comprises motor, toggle, two bearing seats, major axis, motor and two bearing seats are arranged on experiment table top, two bearing seats are linearly arranged the edge that is arranged on experiment table top, one end of major axis is connected on the output shaft of motor by shaft coupling, the other end is through one of them bearing seat and stretch out in experiment table top, crank one end of toggle is connected to by being rotationally connected that one end that major axis stretches out in experiment table top, one end of the other end and connecting rod is rotationally connected, the other end of connecting rod and rocking bar one end are rotatably connected, the other end of rocking bar connects another one bearing seat, this comprehensive experiment table is when doing the vibration experiment table of linkage assembly combination structure, while being the nonlinear vibration experiment of elastic linkage mechanism, motor drives major axis rotation, major axis drives crank and connecting rod movement, because linkage assembly has the impact of many non-linear factors in operational process, the non-property line factor that for example the large geometry deformation of member causes, the non-linear factor that bearing clearance, member connection place causes etc., linkage assembly will produce combination resonance, ultraharmonic resonance, inferior humorous resonance, the nonlinear vibration characteristics such as multiple resonance, by sensor installation on linkage assembly, obtained experimental data is analyzed, process, can complete the unitized construction nonlinear vibration experiment of this linkage assembly, but when doing the experiment of semi-girder or simple beam structure, change structure model not, still adopt the structural model of aforementioned link mechanism, in the analysis of the < < elastic linkage mechanism of writing according to Zhang Ce and design > > mono-book in 148th～151 pages about the description of the feature of Motor-Elastic Linkage Mechanism System, crank in this experiment table can be considered semi-girder, connecting rod and rocking bar can be considered free beam, therefore, when such comprehensive experiment table is done the vibration experiment of overhanging beam, crank is considered as to semi-girder, the other parts of Motor-Elastic Linkage Mechanism are when considering as an additional mass, when this comprehensive experiment table is done the vibration experiment of free beam, connecting rod or rocking bar are considered as to free beam, same by Motor-Elastic Linkage Mechanism except being considered as the part of simple beam structure, other parts are all considered as an additional mass, such comprehensive experiment table can complete the vibration experiment of semi-girder or simple beam structure, but because extention Mass Calculation is got up quite difficult, obtained experimental data also needs extention quality to take into account and analyze, and Data Processing in Experiment is got up quite loaded down with trivial details, simultaneously, semi-girder while doing vibration experiment due to this comprehensive experiment table or simple beam structure are still linkage assembly, semi-girder or simple beam structure model while being different from General Oscillation experiment, for example, when connecting rod or rocking bar are considered as to simple beam structure and do vibration experiment, connecting rod and rocking bar are all difficult to be a horizontal linear, it is often the vibration experiment of doing when connecting rod and rocking bar inclination, enable to be a horizontal linear, kinetic characteristic due to linkage assembly itself, regulate also cumbersome, to use, bring certain limitation.
Summary of the invention
