The impact type penetrator is a compact, lightweight and low power consumption device, using internal hammering mechanism to move downward by compaction of lunar soil in space exploration. This paper proposes an optimal design method for the impact type penetrator. The method main to optimize the structure parameters for housing element (M2), suppressor element (M0) and hammer element (M1) of the...
Recently, more and more AMB (active magnetic bearing) have been applied in automobile, airplane and submarine, where the base motion can not be ignored. Under these conditions, the dynamic model which considered the stiffness of the base as infinity is inaccuracy because of the large influence of the base motion. To investigate the dynamic characteristic of disk-shaped magnetic suspended rotor active...
The longitudinal motion equations were built by mathematical model of target drone movement. The longitudinal linearized equation was got by the lineairzation of longitudinal motion equations. The modality character was analysed by the solution. According to remolding motion, the effection on dynamic stability by flight speed, height and centroid position variation was researched and corresponding...
