Available in PDF, EPUB and Kindle. Book excerpt: Applicability of the finite element method in metal-forming process modeling has been expanded and the use of its capability for solving industrial problems has been demonstrated in the area of; (1) spread analysis in three-dimensional forming processes, (2) perform design and (3) calculation of residual stresses involved in metal forming. In the analysis of spread, sideway spread in block compression between two parallel flat plates was analyzed, using simplified three dimensional eight-node elements. The investigation has been extended to the development of general three-dimensional finite element technique and, the analysis of open-die forging was conducted for producing two size bars. A novel approach to preform design by tracing a loading path backward from a given final configuration was applied to precision preform design in plane-strain rolling. The technique was extended to include the temperature calculation in the scheme and applied to precision preform design in nosing at elevated temperatures. For the investigation of residual stresses, a comprehensive review on the subject has been made, and the finite element program was developed for the determination of residual stresses for radial forging. Keywords: Plastic deformation, Radial forging, Open-die forging, Preform design, Shell nosing.

Download or read book Modeling Analysis and Control of Hydraulic Actuator for Forging written by Xinjiang Lu and published by Springer. This book was released on 2017-12-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 forging conditions, 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.
