Abstract
The invention relates to a horizontal vibration test clamp, comprising a pedestal and a vertical frame, wherein the vertical frame is perpendicular to the pedestal; the lower edges of the vertical frame are fixedly connected with the upper surface of the pedestal; the lower surface of the pedestal is connected with a vibrating table; the vertical frame is located on the middle part of the pedestal, so that the upper surface of the pedestal is divided into two roughly-equal cabinet bottom installation faces; the vertical frame comprises two cabinet back connection faces which are parallel with each other and perpendicular to the upper surface of the pedestal. By the adoption of the horizontal vibration test clamp, a vibration test can be simultaneously implemented on two standard cabinets; therefore, the test efficiency is improved greatly, the development period is shortened, and the development cost is lowered.
Description
Technical field
The invention belongs to the vibration test technology field, particularly a kind of horizontal vibration test fixture that can simultaneously be tested the accurate rack of two station symbols.
Background technology
The vibration test initial stage is applied to aerospace field, has been widely used in now the fields such as railway, communications and transportation, building, earthquake simulation, dynamic power machine, boats and ships.Along with the requirement to product reliability is more and more higher, especially Aero-Space and ship domain, seem particularly important as the vibration experiment development of reliability test key equipment.Vibration test fixture is for product is fixed on vibration table surface, and the vibrational energy of shake table is passed to the device of test products, and the fine or not direct relation of fixture performance the quality of vibration test quality.
The fixture of existing standard rack vibration test is for single cabinet design, as article " dynamic structure design of electronics rack vibration test fixture " (Zhang Jingfeng [J] electric mechanical engineering 2005,21 (2): 29-31) and " Vibration Test Fixture Design for Vehicle-borne Electronics Cabinet " (look into build new, Liu Jicheng [J] modern radar 2007,29 (8): 35-36) described; Due to the limitation of vibration table, a horizontal vibration platform can only be installed the accurate rack of a station symbol and carry out vibration test simultaneously.
Therefore, the problem that prior art exists is: the efficiency of standard cabinet vibration test is low, thereby causes a large amount of of rack to be tested to overstock, and has extended the lead time of rack, has increased development cost.
Summary of the invention
The object of the present invention is to provide a kind of horizontal vibration test fixture, can significantly improve the efficiency of standard cabinet vibration test, shorten the rack lead time, save development cost.
The technical solution that realizes the object of the invention is: a kind of horizontal vibration test fixture, comprise base and the stand vertical with base, the lower edge of stand is fixedly connected with base upper surface, base lower surface connects shake table, described stand is positioned at the middle part of described base, base upper surface is divided into to two racks bottom installed surfaces about equally, and described stand comprises and being parallel to each other and two the rack back joint faces vertical with base upper surface.
The present invention compared with prior art, its remarkable advantage:
1, improve vibration test efficiency: when many racks wait while carrying out vibration test, can by two racks simultaneously clampings on shake table, be tested, improve test efficiency, shorten the rack lead time;
2, save the rack development cost: the shortening lead time itself just means the saving development cost, simultaneously due to the working time that can reduce shake table, saves energy consumption;
3, safer: because test efficiency improves, thus the potential safety hazard of avoiding the long-time non-stop run of shake table to bring.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The accompanying drawing explanation
The structural representation that Fig. 1 is horizontal vibration test fixture of the present invention.
The outline drawing that Fig. 2 is horizontal vibration subjects-standard cabinet.
Fig. 3 is the outline drawing after horizontal vibration test fixture installation code rack of the present invention.
In figure: 1 base, 11 base upper surfaces, 111,112 rack bottom installed surfaces, 12 base lower surface, 2 stands, 21,22 rack back joint faces, 3 oblique pull reinforcements, 4 stiffeners.
The specific embodiment
As shown in Figure 1, horizontal vibration test fixture of the present invention, comprise base 1 and the stand 2 vertical with base, the lower edge of stand 2 is fixedly connected with base upper surface 11, base lower surface 12 connects shake table, stand 2 is positioned at the middle part of described base 1, base upper surface 11 is divided into to two rack bottom installed surfaces about equally, i.e. the first rack bottom installed surface 111 and the second rack bottom installed surface 112, stand 2 comprises and being parallel to each other and two the rack back joint faces vertical with base upper surface 11, i.e. the first rack back joint face 21 and the second rack back joint face 22.
So, the first rack bottom installed surface 111 and the first rack back joint face 21 are for the accurate rack of a station symbol is installed, and the second rack bottom installed surface 112 and the second rack back joint face 22 are for installing the accurate rack of another station symbol.The standard cabinet bottom is connected with the rack bottom installed surface of this fixture by bolt, and the standard cabinet back is connected with bolt with the rack back joint face of this fixture by the back damper.
Base lower surface 12 use bolts are connected with vibration table surface.
Like this, connection by horizontal vibration test fixture of the present invention, just the accurate rack of two station symbols can be installed on a shake table, the accurate rack of two station symbols is carried out to vibration test simultaneously, thereby test efficiency can be risen to twice, to shorten the rack lead time, save development cost, extend the service life of shake table, reduce the potential safety hazard that the shake table long time continuous working brings.
Certainly, this fixture with the accurate rack of a station symbol can only be installed be tested.
For guaranteeing good connectivity robustness, improve test effect, the flatness of the rack back joint face 21,22 of stand 2 preferably is not more than 2mm.
In like manner, the flatness of base lower surface 12 is not more than 0.5mm.
In order to strengthen the rigidity of horizontal vibration test fixture of the present invention, between base 1 and stand 2, also with oblique pull reinforcement 3, be fixedly connected with.
More firm for guaranteeing that base 1 is connected with stand 2, base 1 also is provided with the junction of stand 2 stiffener 4 be fixedly connected with stand 2 with base 1 simultaneously.
For alleviating the fixture deadweight, base 1 is preferably made by H shaped steel.
Same reason, stand 2 is preferably made by H shaped steel.
