摘要
Abstract
A rapid prediction model of solid propellant burning rate based on near infrared spectroscopy was established by means of the near infrared spectroscopy technology.The model was optimized by spectral range screening and spectral preprocessing.The model was evaluated by the internal verification and the external verification to verify its precision and accuracy.The results show that the testing time of the fast prediction model for solid propellant burning rate based on near-infrared spectroscopy technology is about 2 minutes,the deviation range of burning rate is-0.122～0.067 mm/s,the relative standard deviation of precision testing is≤0.4%,and the accuracy testing deviation is-0.029～0.057 mm/s.This method can quickly predict the burning rate of solid propellant in the mixing stage of slurry,and provides a simple,fast,stable and reliable new method for measuring burning rate.关键词
