Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book describes load modeling approaches for complex work pieces and batch forgings, and demonstrates analytical modeling and data-driven modeling approaches for known and unknown complex forging processes. It overcomes the current shortcomings of modeling, analysis and control approaches, presenting contributions in three major areas: In the first, several novel modeling approaches are proposed: a process/shape-decomposition modeling method to help estimate the deformation force; an online probabilistic learning machine for the modeling of batch forging processes; and several data-driven identification and modeling approaches for unknown forging processes under different work conditions. The second area develops model-based dynamic analysis methods to derive the conditions of stability and creep. Lastly, several novel intelligent control methods are proposed for complex forging processes.One of the most serious problems in forging forming involves the inaccurate forgingconditions, velocity and position offered by the hydraulic actuator due to the complexity of both the deformation process of the metal work piece and the motion process of the hydraulic actuator. The book summarizes the current weaknesses of modeling, analysis and control approaches. are summarized as follows: a) With the current modeling approaches it is difficult to model complex forging processes with unknown parameters, as they only model the dynamics in local working areas but do not effectively model unknown nonlinear systems across multiple working areas; further, they do not take the batch forging process into account, let alone its distribution modeling. b) All previous dynamic analysis studies simplify the forging system to having a single-frequency pressure fluctuation and neglect the influences of non-linear load force. Further, they fail to take the flow equation in both valves and cylinders into account. c) Conventional control approaches only consider the linear deformation force and pay no attention to sudden changes and the motion synchronization for the multi-cylinder system, making them less effective for complex, nonlinear time-varying forging processes subject to sudden changes.…

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book introduces readers to ancient Chinese communications with other ethnic communities that lived west of Dunhuang along the ancient Silk Road. These ethnic groups included the Yuezhi and the Xiongnu (Huns), the Sogdians, the Tubo (Tibetans), the Huihu (Uigurs), and the Khotanese. Offering detailed descriptions of Chinese interactions with these peoples, it offers readers a clearer picture of China's ancient and medieval history, particularly the spread of Buddhism and other religious faiths, military operations like the Tibetan occupation and those under the Guiyijun (Return-to-Allegiance) regime, socioeconomic activities, and artistic efforts to create the Buddhist Grottoes. …
