يعرض هذا البحث طرق النمذجة الحاسوبية عند تركيب المعدات في معامل درفلة الحديد من أجل قياسات أبعاد الآلات، التي أصبحت أكثر أهمية شيئاً فشيئاً في السنوات القليلة المنصرمة. و يحدد الشروط المسبقة المثالية لمحاكاة نظام القيادة الخاص بالأنظمة الفرعية الميكانيكية و الكهربائية. حيث تتكون أنظمة القيادة الكهربائية من عناصر متعددة لها تقنية خاصة بها مع مقاييس زمنية، و آلات كهربائية، و أنصاف نواقل، و دارات تحكم بدءاً من وحدات تشكيل و توليد نبضات القدح إلى سلسلة من المنظمات لتحسين الأداء. و هذا يتطلب محاكاة كل من المكونات الميكانيكية و الكهربائية في أنموذج واحد. يعرض برنامج المحاكاة المنتظمة إمكانية دمج النمذجة الميكانيكية مع المتطلبات الكهربائية. حيث سيتم في هذا البحث توصيف التصميم بمساعدة المحاكاة و علاقته مع الاهتزازات الناجمة عن عزم الفتل و ذلك باستخدام أنظمة القيادة.
This paper deals with computer simulation methods when constructing the equipment in iron rolling mill plants for dimensioning machines, which have become more important in the recent years. And it determines the ideal prerequisites to simulate driving system for electrical and mechanical subsystems. The drive systems is built around several components which have their own technology and multiple time-scales: electrical machines, power semiconductor, control circuits from the firing sequences to the different regulators. This requires the simulation of both the electrical and mechanical components in one model. The use of a uniform simulation program offers the possibility to combine in mechanical modeling with the electrical necessities. This research will be in the description of the simulation-aided design and its relationship with vibration caused by the twisting torque using the drive systems.

This paper presents a study aimed at improving the performance of the machine, hot steel rolling, and make them conform to international standards, where the study includes two phases: the first includes mathematical modeling and simulation programmi
ng language with a rolling machine. The second phase will include the development and testing of alternative control systems.
I tested the validity of this model through analyzes of performance curves derived from simulated and compared with the values of the curves and tables station real taken from the HSRMP. Through ensure this form to the parameters of the system characteristic variables representing the performance of the real station, this makes it a useful tool allows simulation of plant performance, explain the behavior of variables The test cases in addition to the possibility of change work and operating strategies to improve the overall operation. From this model performed the initial analysis, which proved the possibility of improving the performance of the station to implement the following modifications:
• Reduce the value of hard integrative models associated with the rings are positioned in the final stage.
• unification of all evil ratios for nutrition workshops.
• Revolving transfer is located in the last phase .
Note: HSRMP ( Hot strip rolling Mill plant ) .
It is a cross in the hydraulic systems with long pipes case modeling of the hardest and most important cases in search. Of the most important and is considered Query to achieve study the changing resistance model is used to describe the changing liqu
id flow in the tube. As described by knowing the nature of the shear stress to the pipe wall and also know the nature of the flow ( laminar or turbulent ). The results of simulations of hydraulice shock caused by the sadden move of the hydraulic control valve which studied in the following cases:
1- Hard to improve the discharge of the pump rate.
2- Improve the discharge of the pump variable rate finally; compare the results of computer simulations with experimental results.
The turbine control purpose is to achieve the maximum limit of wind power,
associated with reducing the mechanical loads. The current control techniques do not take
into consideration the dynamical side of wind and turbine, which leads to power los
s. To
improve the effectiveness of the
nonlinear controllers, we can derive the nonlinear feedback controllers for static and
dynamic conditions in order to reach the wind speed estimator. Then we can test the
controllers by a mathematical model applied on the wind turbine simulator, with
disturbances and noise. The results have shown important improvements in comparison
with the current used controllers.

The use of modern methodologies and techniques a new approach to evaluate the
process of engineering design in the industry pay to use in evaluating the speed in large
cans mechanisms design.
The gearbox that is designed for big vehicles for off-r
oad driving conditions need
portal axle which installed between the wheel and the axle shaft to give higher ground
clearance to the vehicle.
The modeling and simulation of spur gear which contacted with portal axle is
important to predict the actual motion behavior, but it's so complicated to study.
In this study, it'll analysis the portal axle by using finite element method (FEM),
modal analysis will simulated on three different combinations of gear train system, the
three gear trains being analyzed are: gear train without idler gear, one idler gear and two
idler gears.
FEM static stress analysis will also simulated on three different gear train to study
the gear teeth bending stress and contact stress behavior of the gear trains in different
angular positions from °0 to °18 degree.
