摘要
质心是运载火箭控制的主要技术参数,会影响飞行的成败,由此,需要对火箭质量、质心测量设备的数据准确性和精度进行评估。为验证某型火箭质量、质心测量设备的测量精度是否能满足要求,对比有限元分析结果和测量数据,进行火箭质量、质心测量设备的校准试验。介绍了试验过程,并对试验结果进行了分析。
Centroid is the main technical parameter of launch vehicle control,which will affect the success of flight.Therefore,it is necessary to evaluate the data accuracy and precision of rocket mass and centroid measurement equipment.To verify whether the measuring accuracy of a certain type of rocket mass and centroid measurement equipment can meet the requirement,a calibration test of rocket mass and centroid measurement equipment was conducted by comparing the finite element analysis results and measurement data.The test process was introduced,and the test results were analyzed.
