Abstract:According to the characteristics and demands of dynamic thrust measurement for orbit/attitude control rocket engine, the dynamic thrust measurement system is researched and designed. The dynamic model is discussed and the dynamic ability is investigated through mode analysis theoretics, then its mathematic model and transfer function are set up, which are proved reliable by experiments. The dynamic transfer characteristic is analyzed and it is proved that the system is authentic with potty damp. Combining the model, the testing signal is changed into Fourier progression, then the dynamic testing errors are obtained when the system dynamic ability and different frequency signals progress in algebra. It is shown that the system dynamic ability satisfies the design requirements.
