小质量弹丸质心测试设备的设计及精度分析

Design and Accuracy Analysis of the Low-mass Projectile’s Centroid Test Equipment

在军工及民用领域,许多关键产品及零部件需要进行质心的测试,质心参数决定了产品的性能及质量,对弹丸质心的测试可确保产品性能的稳定可靠,满足军工需求。针对小质量弹丸质心的测量设计了一种新的质心测试设备,包括测量架部分、升降机构部分、L0测量机构部分以及传感器安装等部分组成,经实际分析,小质量弹丸质心测试设备的测试精度可达0.0319 mm,实现了较高的测试精度,研究成果可为具有回转结构产品的质心测试提供理论依据和技术支持。

Many key military or civilian products and components requires centroid tests,whose parameters determine the performance and quality of the product.The centroid test of the projectile can ensure its stability and reliability to meet the needs of the military.We designed a new centroid test equipment for projectiles,including measuring frame,lifting mechanism,L0 measuring mechanism and sensor installation Through the analysis of the experiment,we found that the test accuracy of the small-mass projectile centroid test equipent can reach 0.0319 mm,which achieves a higher test accuracy.This paper can improve the theoretical basis and technical support for the centroid test of products with rotary structures.
