Description

technical field [0001] The invention relates to the technical field of cannonball manufacturing, in particular to a multifunctional device for testing the performance index of a steering gear. Background technique [0002] In the precise strike of shells, the steering gear controls the flight attitude and trajectory of the projectile. Therefore, it is necessary to design a high-performance steering gear. The response speed when changing the trajectory when the body is running, the combination of the two will comprehensively reflect the strike performance of the whole body, therefore, it is necessary to verify the rotation angle and rotation frequency of the steering gear blade. [0003] In addition to bearing its own weight during the flight of the projectile, it will also encounter constant speed wind and gust wind, which will produce constant resistance and elastic resistance on the wings. Therefore, it is necessary to verify whether the performance of the steering gear ag...

Problems solved by technology

[0004] Whether it is to test the rotation angle and rotation frequency of the steering gear wings, or to test the performance of the steering gear against elastic resistance, most of them currently use the physical principle of levers to measure each wing separately, which will lead to large errors in test results. , the test efficiency is low, and it is difficult to achieve real-time feedback

[0005] As for the performance of testing the anti-constant resistance of the steering gear, most of the previous methods use the hoisting method to measure the performance of each wing against the constant resistance, but this method is inconvenient to assemble the counterweight, and the error of the test results is relatively large. The test efficiency is low, and it is difficult to achieve real-time feedback
