In this paper, a phase quantization method named appropriate recursive comparative compensation method (ARCCM) is presented. ARCCM develops on the basis of recursive comparative compensation method (RCCM) using the phased array antenna virtual bit technology (VBT). In allusion to one-dimensional uniform linear array, ARCCM is analyzed and simulated. Compared with other methods, the beam pointing accuracy...
Failure analysis shows that increased die temperature caused by severe plastic deformation of material and heat conduction between hot billet and cavity significantly affects the distortion of gear cavity in steel synchronizer ring forging process. The forging process of steel synchronizer ring and die temperature distribution under different forging conditions are analyzed through finite element...
Wedged-ring connection is a very new method for two tubular bodies and has been used in structures such as torpedoes, sea mines and spacecrafts. Compared to bolted flange coupling systems, the force transmission is relatively complicated and the strength is relatively weak in the joint zone of the wedged-ring connection structure, therefore it is necessary to analyze parametric sensitivity and design...
The bandwidth of fast steering mirror (FSM) is about several tens of hertz which is related to Tylar frequency of atmospheric turbulence, and the bandwidth of deformable mirror ranges from several tens to hundreds hertz relates to Greenwood frequency of atmospheric turbulence. According to practical experience, the ratio of fast steering mirror and deformable mirror should be from one is to five to...
