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.

Download or read book On the Dynamics of High speed Drop Forging Process written by V. P. Chernichenko and published by . This book was released on 1967 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and experimental studies have been made of the dynamics of a high-speed forming process depending on the rate, temperature, degree of reduction, and type of metal. AV aluminum-alloy bars 50 mm in diameter and 75 mm high were tested by a high-speed explosive-forming press with hammers weighing from 5 to 120 kg at a rate of 18 to 120 m/sec. On the basis of the experiments, some oscillograms of the deformation force and time and diagrams of the propagation of impact stresses were plotted. Experimental and industrial models of high-speed forming presses are also presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Despite the increased understanding we now have of materials and their properties, selecting materials for a given application remains a daunting, non-trivial task. The volume of data, inadequacies in the data, and the tens of thousands of materials to choose from can overwhelm the would-be user. The Materials Selector addresses all the problems faced by materials scientists and engineers. In its three volumes you will find the properties, performance, and processability of metals, plastics, carbon and graphite, glasses, ceramics, polymerics, and composites. The characteristics and comparative economics of the manufacturing routes that convert these materials into engineering components.

This book was released on 2012-12-06 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal aim of this text is to encourage the development and application of numerical modelling techniques as an aid to achieving greater efficiency and optimization of metal-forming processes. The contents of this book have therefore been carefully planned to provide both an introduction to the fundamental theory of material deformation simulation, and also a comprehensive survey of the "state-of-the-art" of deformation modelling techniques and their application to specific and industrially relevant processes. To this end, leading international figures in the field of material deformation research have been invited to contribute chapters on subjects on which they are acknowledged experts. The information in this book has been arranged in four parts: Part I deals with plasticity theory, Part II with various numerical modelling techniques, Part III with specific process applications and material phenomena and Part IV with integrated computer systems. The objective of Part I is to establish the underlying theory of material deformation on which the following chapters can build. It begins with a chapter which reviews the basic theories of classical plasticity and describes their analytical representations. The second chapter moves on to look at the theory of deforming materials and shows how these expressions may be used in numerical techniques. The last two chapters of Part I provide a review of isotropic plasticity and anisotropic plasticity.
