Abstract
The invention relates to a gear system failure simulation comprehensive experiment table outer cover with the protection function. The outer cover is made of PVC materials, and the bottom of the outer cover is provided with six vertical through holes which correspond to threaded holes of an experiment table and are used for positioning and connecting. The top of the experiment table is of an arch shape, so that experiment operation space is ensured, and the operation condition of the experiment table is observed conveniently and directly. After the outer cover is installed on the experiment table, under the condition of high speed operation, the probability that an experimenter is bounced and injured by accidently-splashed substances from the experiment table is greatly reduced, and meanwhile the probability that operational failure is caused when foreign matter falls into the experiment table is reduced. According to the gear system failure simulation comprehensive experiment table outer cover, failure feature signals of the experiment table cannot be affected when characteristic frequency and frequency multiplication are aroused.
Description
Technical field
The present invention relates to a kind of experiment table outer cover with defencive function, relate to gear train fault simulation comprehensive experiment table field, relate in particular to a kind of gear train fault simulation comprehensive experiment table outer cover with defencive function.
Background technology
In scientific experiment research work and classroom instruction task to engineering actual gear driving unit fault, for the ease of simulation analysis, usually introducing can model engineering actual middle gear kinematic train most common failure and light, attractive in appearance, easy-to-dismount experiment table as the current techique research means.Along with people cause directly and the indirect economic loss impact enterprise attention and the mechanical fault of plant equipment safe handling, people have proposed more and more higher requirement to the security performance of plant equipment.In gear train fault simulation comprehensive experiment table design process, usually after finishing the processing of experiment table main part, lack the corresponding establishment to the protection of gear drive malfunction test platform operation experiments personal security.
For addressing the above problem, the present invention proposes a kind of gear train fault simulation comprehensive experiment table outer cover with defencive function.Comprehensive its practicality of this experiment table outer cover and economy adopt the PVC material to take into account simultaneously its high performance-price ratio and functional diversity characteristics, can guarantee that gear distress simulation combined test table experiment effect makes again its dismounting easy.
Summary of the invention
The object of the present invention is to provide a kind of gear train fault simulation comprehensive experiment table outer cover with defencive function, this outer cover comprises: outer cover body and the through hole corresponding with the experiment table threaded hole.
For achieving the above object, the technical solution used in the present invention is: a kind of gear train fault simulation comprehensive experiment table outer cover with defencive function.This gear train fault simulation comprehensive experiment table outer cover comprises by six of the outer cover body of PVC material manufacturing and outer cover bottoms and the through hole of experiment table threaded hole to being applied to be located by connecting.
Compare with other gear train fault simulation comprehensive experiment table, the present invention has the following advantages:
1, the present invention is in conjunction with the many requirements of comprehensive experiment table; adopt integrated design to reduce manufacturing cost; should not exist any metal to connect by outer cover body simultaneously; the whole PVC material that adopts is not only economical and practical but also preferably transparency is arranged, and has good protective effect and can not observe experiment table inside to exert an influence.
2, the outer cover that is installed on the experiment table can carry out playing in the process in experiment Protection personnel's effect; also can be in the situation that run up and greatly reduce the experimenter and suffer the experiment table accident to sputter the probability of object bullet wound; reduce simultaneously foreign matter and fall into the probability that experiment table causes its operational failure, experimenter and plant equipment are played a protective role.
3, by adopting this experiment table outer cover, various fault is being carried out in the simulated operating procedure, can not affect the experiment table fault characteristic signals because evoking outer cover natural frequency and frequency multiplication thereof, can well guarantee quality of experiments.

Embodiment
Below with reference to accompanying drawing patent of the present invention is described further.
Be illustrated in figure 1 as this gear train fault simulation experiment table cover structure schematic diagram.Set up the three-dimensional model of this gear train fault simulation experiment table outer cover with SolidWorks, this outer cover body 1 adopts the bottom of PVC material and outer cover body 1 that the through hole 2 of six vertical directions is arranged; The overall dimensions of outer cover body 1 is corresponding with experimental operation table; The experiment table top adopts arch design to guarantee the experimental implementation space, can make things convenient for the ruuning situation of direct observation experiment operator's console.
Be illustrated in figure 2 as gear train fault simulation experimental operation table schematic three dimensional views, be illustrated in figure 3 as the three-dimensional assembling of gear train fault simulation experiment table outer cover schematic diagram.Be provided with the threaded hole 4 of three row and gear train experiment table axially parallel at gear train fault simulation experimental operation table 3; The physical dimension of outer cover body 1 is according to the profile design of gear train fault simulation experimental operation table 3; The thickness that designs outer cover body 1 is 8mm, adopts simultaneously the PVC material to be enough to the iron filings bullet wound that the Protection operating personnel are not sputtered; The bolt that it is M5 that six groups of models are adopted in the bottom of outer cover body 1 and gear train fault simulation experimental operation table 3 are connected and fixed, and have improved the reliability of gear train fault simulation experimental operation table 3.
Be illustrated in figure 4 as 1 rank fault natural frequency figure of outer cover body, Fig. 5 is 2 rank fault natural frequency figure of outer cover body, and Fig. 6 is 3 rank fault natural frequency figure of outer cover body, and Fig. 7 is 5 rank fault natural frequency figure of outer cover body.For the fault natural frequency impact of the outer cover body 1 of analyzing experiment table on this gear train fault simulation experiment table 3, the model of outer cover body 1 is imported among the ANSYS, and the parameters such as the material properties of this model, density are arranged, impose restriction and carry out static state and find the solution the front 5 rank natural frequencys that draw under the static state.
Be illustrated in figure 8 as the ADAMS model of gear distress simulation combined test table, Fig. 9 is the simulate signal that contains the gear train fault, and Figure 10 is the experiment table simulate signal that contains the gear train fault.The gear train fault simulation comprehensive experiment table model that establishes is imported ADAMS carry out dynamics simulation under the different faults, in the subsequent treatment module of ADAMS, can obtain the fault characteristic frequency under the various different faults, can not disturb the fault characteristic signals generation of experiment table by the natural frequency of the outer cover body of contrast verification.
Compare by natural frequency and the fault characteristic frequency of experiment table under the different faults running status with outer cover body, outer cover body can not affect because evoking inherent feature frequency and frequency multiplication the fault characteristic signals of experiment table as can be known.
