Embodiment Construction

[0014] The concrete implementation of the present invention is described in detail in conjunction with accompanying drawing and technical scheme: as figure 1 As shown, the upper end surface a of the loading flange 5 is matched with the lower end surface f of the adapter end 1, and the loading flange 5 is rigidly connected to the adapter end 1 through bolts 4; the ring frame 2 and the connecting plate 6 are evenly arranged through eight The ribs 8 are welded; the upper end surface c of the calibration flange 7 matches the lower end surface d of the connection plate 6, and the connection plate 6 and the calibration flange 7 are rigidly connected by bolts 4. When assembling, the assembly between the loading flange 5 and the adapter 1 must ensure a certain degree of position and coaxiality; similarly, the assembly of the connecting plate 6 and the calibration flange 7 must ensure a certain degree of position and coaxiality ; During processing, the connection flange surface of the ...

Abstract

The invention discloses a double-force-source thrust vector testing and transferring calibration rack which is used for connecting a force generating device with a dynamometer. The double-force-source thrust vector testing and transferring calibration rack is applied in a thrust force testing system and particularly relates to a rocket thrust force testing system. The double-force-source thrust vector testing and transferring calibration rack is composed of the components of transferring ends, a loading flange, a calibrating flange, mounting bolts, etc. A parallel structure is adopted for the two transferring ends. The two transferring ends are connected with each other through an annular structure. The annular structure is welded with a connecting board through ribs. The two transferring ends are respectively provided with a hoisting hole for measuring two points on the two force sources which are separated from each other by a long distance. The double-force-source thrust vector testing and transferring calibration rack is advantageous in that an integral structure is adopted for the whole body of a transferring rack; relatively high rigidity and high inherent frequency are realized; a dynamic measurement precision is improved; furthermore a hollow front-projected spoke-shaped structure is adopted for the whole body, thereby reducing self weight, reserving a mounting and debugging space for a calibration device, and realizing simple structure, convenient mounting and convenient adjustment.

Description

technical field [0001] The invention relates to a dual force source thrust vector test transfer calibration frame, which uses two single force source transfer calibration devices in parallel to realize the transfer between the dual force source and the sensor, and is applied to transfers with more than one force source Occasions, especially related to the application of piezoelectric quartz sensors in the field of testing dual-source rocket thrust. Background technique [0002] In the rocket thrust test system, due to the propellant pipeline and heat insulation equipment at the front end of the engine, it cannot be directly installed on the dynamometer, but must be transferred through an adapter frame. Reduce the conduction of heat to the dynamometer, which will have a greater impact on the measurement results. At present, there are many adapter devices used to connect the force source generating device and the dynamometer at home and abroad. It is mainly responsible for t...
