摘要

A model of thrust measurement system in pulse detonation engine was established to study the dynamic characteristics of the thrust measurement system. The frequency response of the measurement system was calculated by the finite element calculation. The theoretical transfer function of the thrust measurement system was derived and fitted. A single-shot detonation in a tube was calculated, whose axial force on the closed end was used as the input of the measurement system. The accuracy of the measurement results was influenced by the mechanical vibration of the measurement system. In order to reduce the impact of the measurement system’s mechanical vibration, the damping ratio of the measurement system should be improved, and a damping compensation unit was designed. The post-processing program based on the damping compensation method was written, and the applicability of the program was verified. After the correction of the damping compensation unit, the input was well reproduced.
