“…For simulating the press anvil and the edger tools (rollers), analytical rigid bodies are employed. Coulomb friction model with friction coefficient of 0.35 is used for modeling the contact between the workpiece and tools both in the vertical rolling and SP processes (Chun et al, 2003(Chun et al, , 2005Shangwu et al, 2000aShangwu et al, ,b, 2001Shangwu et al, , 2003.…”

“…Today, quality steel sheet and strip become an important symbol to measure the level of Iron and steel industry for a country. [1][2][3][4][5] In recent years, in order to adapt the fierce competition, reducing energy consumption, improving product quality and productivity, and user's specific requirements of width of the strip, the producers need more different kinds of slab. To realize the convergence between continuous casting and continuous rolling, the technology of slab side pressing is an online regulation width can meet these requirements, and can effectively reduce the specification and specs of continuous casting slab.…”

It is based on the advantages of virtual prototyping technology, the dynamics mathematic model was established for the large mechanism by applying multi body dynamics theory. In order to adapt the users to special request of the strip width size, appeared the continuous casting and continuous rolling technology, and greatly reduce the width types of continuous casting. The components of the equipments are often considered the rigid body. The precision is not high premise in the process of work, usually the parts works as elastic under the high speed and the heavy load, neglects various components the elastic function will cause the result error, even will be wrong. Studied analysis dynamic characteristic of the adjustment width machine, and analyzed the component in detail for the rigid body or the elastic. The results provide the theoretically support to work out adjustment the width potentialities and strength analysis of the key parts. Keywords: Rigid-elastic, dynamic system, key parts, large mechanism, heavy load.Разработана динамическая математическая модель для больших механизмов, базируясь на технологии виртуального макетирования, путем применения многочастичной динамической теории. Для адаптации к специальным требованиям по ширине полос выработаны технологии непрерывного литья и непрерывной прокатки, существенно ограничивая требования по ширине процесса литья. Компоненты оборудования часто рассматриваются как твердые тела. Точность невелика, т.к. в процессе работы детали часто проявляют эластичность при высокой скорости или большой нагрузке, и пренебрежение этим фактором приведет к ошибочным или даже полностью неправильным результатам. Исследованы динамические характеристики согласования с деталями механизма и проведен анализ компонентов на предмет их твердости или эластичности. Результаты дают теоретическое обоснование для возможности регулировки по ширине и анализа механической прочности основных деталей.Гнучкий імпульсний відгук многостержневих з'єднань при великих навантаженнях.

Компоненти обладнання часто розглядаються як тверді тіла. Точність невелика, тому що в процесі роботи деталі часто виявляють еластичність при високій швидкості або великому навантаженні, і нехтування цим фактором призведе до помилкових або навіть повністю неправильних результатів.

Результати дають теоретичне обгрунтування для можливості регулювання по ширині і аналізу механічної міцності основних деталей.

“…The slab deformation behaviours have been mainly investigated by industrial tests, 4,5 laboratory experiments [6][7][8][9][10][11] and finite element (FE) simulations. [12][13][14][15][16][17][18][19][20] Okado et al 6 simulated slab deformation during vertical rolling at a laboratory mill and formulated the dog bone shapes by regression analysis of the experiment results. According to the regression analysis of measured values from a production mill, formulae for strip width prediction in V-H rolling were derived by Shibahara et al 4 .…”

From a new viewpoint to improve plate plan view pattern during hot rolling, a plate edging process was proposed to roll back only the plate width spread of conventional rolling in this paper. Using commercial finite element (FE) analysis software DEFORM-3D, a three-dimensional rigid plastic FE model for vertical-horizontal (V-H) hot rolling was developed on the basis of a 5 m wide and heavy plate mill. Three hundred and twenty kinds of different V-H rolling processes were simulated by the FE model. Basing on the simulation results, the formation laws of dog bone shape during the vertical rolling and the width spread behaviours during the horizontal rolling were clarified. A plate edging model predicting the plate edging efficiency was established with the aid of an artificial neural network. The plate edging efficiency predicted by this plate edging model agreed well with those predicted by the existing strip edging models when the slab width/thickness ratio was small, which confirmed the validity of the plate edging model. The plate edging model expanded its application scope into the wide and heavy plate hot rolling.
