Technical field
The utility model relates to a kind of Aviation Test machinery, is mainly used in ground simulation test, specifically, relates to a kind of aircraft fuel system ground simulation test platform with center cross mechanism.
Background technology
According to the regulation of aircraft industry standard (HB7169-1995, GJB1003A-2006), aircraft fuel system must carry out ground simulation test in development process, and required equipment is the test turntable of 2DOF.Present known bed stand structure is divided into two kinds: a kind of is the gyro gimbal formula, and another is the beam frame-type.
The gyro gimbal formula generally is comprised of outside frame and inner frame two parts, and framework mostly is the ball node truss structure.The outside frame rotating shaft support is on ground surface platform, and the inner frame rotating shaft support is installed the aircraft fuel oil pilot system of full-scale simulation on the inner frame on outside frame.Be used in the larger aircraft of overload is tested, but test cell velocity of rotation value design comparison is large, but complex structure, parts are numerous, bulky, the capital construction work amount is large, dig the rotation that dell is beneficial to stand, the stand vertex overhead highly reaches tens meters, the installation and maintenance safety factor is low, and the construction period reaches two to three years, and operating cost is expensive, and laid down cost is up to tens million of units, and the periodical maintenance cost is also high.
The beam frame-type mainly is comprised of erecting stage, intermediate beam, column, driver train etc.This kind frame mode is relatively simple, and the little aircraft that can only be used for transshipping is tested, and running stability is poor, integral rigidity and poor stability, and as the monolateral fault of driver train occurs, flutter can occur whole stand, even the phenomenon of rollover damage equipment.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to the needs of reality, and a kind of aircraft fuel system ground simulation test platform with center cross mechanism is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of aircraft fuel system ground simulation test platform with center cross mechanism, comprise test cell body and mounting seat, also comprise roll pressurized strut and pitching pressurized strut, be provided with center cross mechanism between described test cell body and the mounting seat, described test cell body is installed in the described center cross mechanism by two bearing seats, described center cross mechanism is installed on the described mounting seat by two bearing seats, described roll pressurized strut is positioned at described test cell body below and is connected with ground with the test cell body respectively by universal-joint and is connected, and described pitching pressurized strut is positioned at the below of center cross mechanism and is connected with ground with center cross mechanism respectively by linkage and is connected.
Described roll pressurized strut is structure identical two and is symmetricly set in two ends, described test cell body below.
Described pitching pressurized strut is structure identical two and the two ends, below that are symmetricly set in described center cross mechanism.
The beneficial effects of the utility model are:
1. compared to prior art bed stand structure can with simpler structure, realize pitching, roll motion and the binary compound motion of single degree of freedom;
2. cost is lower, and construction cost is low to moderate in 1,000,000 yuan, and the construction period is as short as two to three months;
3. reliability and security is high, even the driver train et out of order flutter can not occur yet, even the phenomenon of rollover damage equipment, be convenient to safeguard.
Description of drawings
The structural representation of Fig. 1 the utility model system.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of aircraft fuel system ground simulation test platform with center cross mechanism, comprise test cell body 1 and mounting seat 2, also comprise roll pressurized strut 3 and pitching pressurized strut 4, be provided with center cross mechanism 5 between described test cell body 1 and the mounting seat 2, described test cell body 1 is installed in the described center cross mechanism 5 by two bearing seats, described center cross mechanism 5 is installed on the described mounting seat 2 by two bearing seats, described roll pressurized strut 3 is positioned at described test cell body 2 belows and is connected with ground with test cell body 2 respectively by universal-joint and is connected, and described pitching pressurized strut 4 is positioned at the below of center cross mechanism 5 and is connected with ground with center cross mechanism 5 respectively by linkage and is connected.Thereby the test article that roll pressurized strut 3 and pitching pressurized strut 4 are mainly used in driving on test cell body 1 and the center cross mechanism 5 motoring ring test playscript with stage directions bodies 1 is done roll, luffing.
Described roll pressurized strut 3 is for structure identical two and be symmetricly set in two ends, described test cell body 1 below.
Described pitching pressurized strut 4 is for structure identical two and be symmetricly set in the two ends, below of described center cross mechanism 5.
Principle of work of the present utility model is summarized as follows:
The test article system rest is on test cell body 1, test cell body 1 is the stage motion part with center cross mechanism 5, drive test cell body 1 by four pressurized strut coordinations, realize pitching, roll motion and the two degrees of freedom pitching of single degree of freedom, the compound motion of roll combination.
When test cell body 1 will carry out luffing, promote center cross mechanism 5 by pitching pressurized strut 4 and rotate around rotation axis.When test cell body 1 carried out roll motion, roll pressurized strut 3 promoted test cell body 1 and rotates around rotation axis.When test cell need to carry out compound motion (luffing and roll motion carry out simultaneously), roll pressurized strut 3 and pitching pressurized strut 4 act on simultaneously and getting final product.
The utility model bed stand structure compared to prior art can with simpler structure, realize pitching, roll motion and the binary compound motion of single degree of freedom; And laid down cost of the present utility model is lower, and construction cost is low to moderate in 1,000,000 yuan, and the construction period is as short as two to three months; Reliability and security is high, even the driver train et out of order flutter can not occur yet, even the phenomenon of rollover damage equipment, be convenient to safeguard.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
