تتطور صناعة الآلات من أجل زيادة سرعتها و قدرتها و إنتاجيتها، لكن ذلك يترافق مع زيادة التأثيرات الميكانيكية و الحمولات الديناميكية بين عناصر و أجزاء تلك الآلات، مما يؤدي إلى نشوء الإهتزازات الميكانيكية فيها و التي تسبب بدورها أضرارا بالغة في الآلات و تؤثر بشكل سلبي على المحيط الذي تتواجد فيه .
تعتبر دراسة الإهتزازات الميكانيكية ذات أهمية بالغة لطلاب العلوم الهندسية و التقنية لمعرفة الإهتزازات التي يمكن أن تنشأ في الآلة التي يجري تصميمها، أو دراسة الإهتزازات الحاصلة في الآلات قيد الإستثمار لعزلها و التقليل من آثارها السلبية. لذلكتم إعداد برنامج نمذجة يوضح طريقة لنمذجة بعض الموديلات الرياضية التي تمثل بعض حالات الإهتزازات الممكنة و يحدد أهم البارامترات التي تصف الحركات الإهتزازية المختلفة، حيث تم اختيار لغة برمجة ملائمة لدمج و إظهار الرسوم و الشروحات النصية و محاكاة الحركة الحاصلة في برنامج واحد، و قد طبق البرنامج على أنواع مختلفة من مسائل الإهتزازات، حيث يتيح عرضها بشكل بسيط و سهل من خلال دقة قيم البارامترات الناتجة مقارنة مع لغات برمجية أخرى مختلفة.
Machine developing aimsto improve its velocity, capability and production,this is
accompanied by increase of Mechanical side effects and the dynamical loads between the
Machines elements and parts, that may conduct to rise the Mechanical vibrations and may
cause a lot of damage in these machines, and cause negative effects on the
environmentaround these machines, the study of Mechanical vibrations has a significant
importance for engineering and technical students, to have knowledge of Mechanical
vibrations that may arise in the machines under design process, or to study the mechanical
vibrations resulting in the machines under use to isolate these vibrations and attenuate of
its negative effects, for that we introduced an simulation program to show and illustrate a
method to simulate some mathematical models representing some of possible types of
vibrations, and to determine the most important parameters that describe the different
vibrations motions, we choose an suitable programing language to merge this simulated
models with an illustration and learning texts and drawings and animations in one
executable application, this application show the models and the results in simple and very
clear manner, and show the results in high resolution comparing with other programing
languages.
