One end of the horizontal following hydraulic cylinder is fixed on the bottom face of the counter-force frame, and the other end of the horizontal following hydraulic cylinder is connected with the horizontal following platform. The horizontal following platform moves on the bottom face of the counter-force frame, and the comprehensive loading platform and the longitudinal loading hydraulic cylinder are arranged in a horizontal moving platform. One end of the longitudinal loading hydraulic cylinder is fixed on the bottom face of the horizontal moving platform, and the other end of the longitudinal loading hydraulic cylinder supports the comprehensive loading platform. The undercarriage loading following device is simple in structure and convenient to use, can simulate an actual working condition of an undercarriage and can conduct loading testing on the undercarriage.
Description
Technical field:
The utility model relates to a kind of product and detects auxiliary device, and especially a kind of alighting gear loads follow-up mechanism, belongs to the Test And Check Technology field.
Background technology:
Alighting gear is widely used in fixed wing aircraft.The various test detecting equipments of undercarriage develop rapidly, and its trend is to simulate the real work situation of alighting gear.Conventional Take-off and Landing frame load test is to carry out the static loading test, can't simulate the stressing conditions of alighting gear real work fully.And the undercarriage load test often need to carry out the multi-aspect power of multiple spot to alighting gear and load, but because the alighting gear lower shake-changing arm rotates because loading longitudinal force, thereby producing transverse shifting, this moves other power is loaded and has produced impact.Therefore, how providing a kind of undercarriage load test, can effectively simulate the alighting gear actual condition, is the technical barrier that those skilled in the art need to solve.
The utility model content:
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of alighting gear to load follow-up mechanism, can effectively simulate the actual condition of alighting gear.
For achieving the above object, the technical solution adopted in the utility model is: a kind of alighting gear loads follow-up mechanism, comprises reaction frame, horizontal compliant platform, comprehensive weighted platform, vertically loading hydraulic cylinder and horizontal follower hydraulic cylinder.One end of horizontal follower hydraulic cylinder is fixed on the bottom surface of reaction frame, and the other end is connected with horizontal compliant platform.Horizontal compliant platform moves in the bottom surface of reaction frame.Comprehensive weighted platform and vertical loading hydraulic cylinder are in horizontal shifting platform.Vertically loading hydraulic cylinder one end is fixed on the bottom surface of horizontal shifting platform, and the other end is supporting comprehensive weighted platform.
The utility model is simple in structure, and is easy to use, can simulate the actual condition of alighting gear, and alighting gear is carried out load test.
Description of drawings:
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of embodiment 1.
The specific embodiment:
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear, intactly description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Give the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
Show as Fig. 1: a kind of alighting gear loads follow-up mechanism, comprises reaction frame 1, horizontal compliant platform 2, comprehensive weighted platform 3, vertically loading hydraulic cylinder 4 and horizontal follower hydraulic cylinder 5.One end of horizontal follower hydraulic cylinder 5 is fixed on the bottom surface of reaction frame 1, and the other end is connected with horizontal compliant platform 2.Horizontal compliant platform 2 moves on the slideway of the bottom surface of reaction frame 1.Comprehensive weighted platform 3 and vertical loading hydraulic cylinder 4 are in horizontal shifting platform 2.Vertically loading hydraulic cylinder 4 one ends are fixed on the bottom surface of horizontal shifting platform 2, and the other end is supporting comprehensive weighted platform 3.Tested alighting gear comprises fixing main pillar 6, energy disperser 7 and lower shake-changing arm 8.Alighting gear is arranged on horizontal compliant platform 2.Installation position displacement sensor in vertical loading hydraulic cylinder 4 is by the position of lengthwise position calculated level follower hydraulic cylinder 5.
Vertical loading hydraulic cylinder 4 and comprehensive weighted platform 3 are arranged on horizontal compliant platform 2, when vertically loading, it is servo-actuated that level is carried out in the displacement of the horizontal follower hydraulic cylinder 5 vertical loading hydraulic cylinders 4 of basis, guarantee that comprehensive weighted platform 3 and alighting gear lower shake-changing arm 8 relative position of really fixing a point is constant, solved the difficult problem of the multi-aspect loading of alighting gear multiple spot.
Therefore, the alighting gear that the utility model provides loads follow-up system, has solved the difficult problem of the multi-aspect loading of alighting gear multiple spot, simulates tested alighting gear fully at the stressing conditions of real work.
To the above-mentioned explanation of the disclosed embodiments, be that this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from marrow or the scope of utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
