Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0024] After the main direction hydraulic power system 7 is connected to the hydraulic oil, it provides power for the calibration of the main direction, and realizes the simulated loading of the main direction force in the X direction; the lateral force is obtained by laterally loading the hydraulic oil Device 2 applies force to the sides of the calibration plate to respectively realize simulated loading in the Y and Z directions. Five sets of threaded holes with the same spacing and the same size are arranged on each station of the upper plate 8 of the support round table, and the side loading device 2 can slide along the key to finally realize the transformation of the three stations. When the two opposite side loading devices 2 are in the two opposite limit positions respectively, the torque M can be rea...

Abstract

The invention provides a high thrust vector vertical type test device structure, belongs to the technical field of sensing and measurement and control, and solves the technical problems that the present solid rocket engine test device has low inherent frequency and small test range so that the engine thrust vector test precision can be enhanced by changing the conventional horizontal structure into the vertical structure. The device comprises an adapter frame, lateral loading devices, an eight-position calibration board, a dynamometer, a key, a connecting cylinder, a hydraulic power system, anupper plate, reinforcing ribs a, reinforcing ribs b, a bearing cylinder and a lower plate. The device is large in measurement range, great in structural processability, high in precision, great in dynamic characteristics and easy to install and debug so that the space force and the moment can be simultaneously tested and the engine thrust vector characteristics can be more comprehensively and accurately tested.

Description

technical field [0001] The invention relates to a large-thrust vector vertical test device structure, which belongs to the technical field of sensing and measurement and control, is applied to the test occasions of high-thrust solid rocket motors, and is of great significance to the thrust vector test of solid rocket motors. Background technique [0002] As a key performance parameter of a rocket engine, the engine thrust vector is of great significance for controlling the attitude of the aircraft and improving the control accuracy. [0003] Most of the existing solid rocket motor thrust vector test devices are of horizontal structure, but the horizontal structure is difficult to ensure that the axis of the test system coincides with the axis of the engine, and with the combustion of the solid rocket motor, the fuel reduction will cause the gravity of the engine to change, which will affect the Lateral force exerts influence, thereby affecting test accuracy. The six-compone...
