Different from traditional P2P systems, individuals nodes of a Federated Service Providing (FSP) system play a more active role by offering a variety of domain-specific services. The service provision control (SPC) problem is an important problem of the FSP system and will be tackled in this paper within a stochastic optimization framework through several steps. The first step focuses on using stochastic...
For space robots, to perform tasks in space, impacts between them and other objects are inevitable. The impact dynamics is studied in the paper. Firstly, the kinematics model and the dynamics model are established for the space robot. Secondly, the impact dynamics model is presented based on the impulse principle. Then, the collision detection is achieved by the analytic geometry and the motion after...
In the paper, the characteristics of mode and harmonic response of the axis of the high-speed motorized spindle are presented with the FEM (Finite Element Method). A dual-dimension model with the FEM is developed and simulated using ANSYS commercial software. The result shows that the rated rotating speed of the high-speed motorized spindle is far smaller than the first-order natural resonance speed,...
