Research on Measurement Systems and Principles of Rocket Geometry

针对体积庞大的火箭弹轴向尺寸和径向尺寸难以测量的问题,提出了一种基于位移传感器的火箭弹几何尺寸测量系统。首先将弹体稳定支撑,然后通过测量装置对火箭弹轴向尺寸、径向尺寸及翼展进行测量,最后对测量结果进行精度分析。结果表明,文中提出的火箭弹几何尺寸检测系统,可用于直径达500mm、长度达5000mm的火箭弹的非接触测量。并实现对火箭弹的径向尺寸和轴向任意两点之间距离以及翼展的测量,具备测量精度高、自动化程度好、测量时间短、实用性强等优点。

For bulky rockets,it is difficult to measure the axial dimension and radial dimension,in order to solve this problem the rockets geometry measurement system was proposed which based on the displacement sensor. Firstly the projectile was supported stably. Then the radial size and axial size of rockets were measured through measuring device.Finally the measurement results were analyzed accurately. The results show that the rocket geometric dimension measurement system can be used for noncontact measurement of rockets which diameter is up to 500 mm and length is up to 5000 mm. The measurement of the distance between the radial dimension and the axial measurement and the wingspan measurement are realized.At the same time it has the advantages of high accuracy,good degree of automation,time saving and practical.
