Abstract AR
تم خلال هذا البحث استخدام التحليل العددي الناتجة من دورة الحرارة التي يتعرض لها مكبس محرك بنزين مصنع من سبائك مختلفة من الألمنيوم.
تم استخدام طريقة العناصر المحددة لحساب توزيع الاجهادات المرافقة للحرارة على المكبس.
استخدم نظام التحليل ANSYS5.4 لتنفيذ عملية النمذجة.
تم بناء نموذجين ثلاثية الأبعاد الأول لحساب توزيع درجة الحرارة خلال المكبس أما الثاني فيستخدم لحساب توزيع الاجهادات الحرارية الناتجة من الانحدار الحراري و اختلاف مادة المكبس.
أوضحت النتائج أن أقصى مدى الحرارة هو (4.3 º C) و يزداد مع نقصان التوصلية الحرارية للمادة.
الإجهاد الحراري يتركز على حافات المكبس و يعتمد على نوع المادة.
Abstract EN
In this paper a numerical analysis is used to analyze the stresses due to thermal cycle with different aluminum alloy of piston .Finite element method was used to evaluate the coupling field (thermal–stress) on the piston .ANSYS5.4 Finite element code is used to carry out the modeling process to determine the coupling stress .Two models with three dimensions are created .The first is used to evaluate the temperature distribution through the piston volume, and the second is used to evaluate the thermal stress distribution due to heat gradient and the material different.
The result show the maximum range of temperatures is 4.3 °C and increases with decreasing of material thermal conductivity .Thermal stress is concentrated on the piston edges and depends on the material types.
