This paper introduces the simulation method of the ballistic missile control system for precision analysis, analyzes the influence mechanism of the ballistic missile control system error on the missiles's impact point, constructs simulation model to control the system accuracy, and on the basis carries out the simulation calculation of the model and analyzes the result.
On the base of studying the forming mechanism of self-excitation vibration and helix lobes in deep-hole boring, the paper established a mechanical model and analysed the effect of the length of the guide pads on the vibration and stability. Moreover, the reasonable length of the guide pads was verified by the experiments of the guide pads testing.
This thesis mainly focuses on the torsional vibration in deep-hole boring, establishes a mechanical model and analyses the effect of the installation position on the torsional vibration, and the reasonable blade installation position was verified by the experiments.
