Research on Flexible Centroid Measurement Method for Segments of Large-Thrust Carrier Rocket

Abstract:

A new flexible centroid measurement method is provided in order to meet actual demands for centroid measurement of large-thrust carrier rocket segments. The method has the benefit of utilizing a laser tracker to accurately measure positions of support points of a weighing sensor and geometrical parameters associated with an attitude status of each segment to be measured, thereby solving the problem of a traditional three-point method that measuring accuracy in centroid measurement depends on both mechanical equipment machining accuracy and positioning accuracy. The analysis result shows that the method provided herein has an engineering application value and can realize measurement to high accuracy, automation and universality for large-thrust carrier rocket segments.
