Abstract

For ignition thrust measurement distortion of solid ramjet in ground test, a dynamic model for thrust measurement system was built.The responses at different excitation signals were obtained by designing and implementing identification test which based on ARMAX model.According to the test results, structure and order were identified and the dynamic model for thrust measurement system was built.Veracity and effectiveness of model were verified by fitting rate analysis and residual whiteness estimation.Time-frequency domain analysis results show that the dynamic model could be used to reflect actual dynamic characteristics of thrust measurement system, laying a foundation for improvement of dynamic characteristics, adding thrust compensation and real signals resume.

Key words： solid ramjet; thrust measurement; dynamically modeling
