Abstract AR
تم في هذا البحث دراسة تأثير النفاذية الغير منتظمة على أداء المساند ذاتية التزييت ذات المحاور الغير متمركزة.
تم اعتماد الشروط الحدية المحسنة عن طريق تطبيق معادلة الزخم التكاميلية على طبقة الزيت.
تم تغير نفاذية المحمل ذاتي التزييت بالإتجاهين المحيطي و القطري للمسند.
لقد وجد أن أستخدام مسند مسامي متغير النفاذية يؤثر على أداء هذا النوع من المساند .
لقد لوحظ نقصان في الضغط الأعظم للمسند و قابلية المسند على تحمل الأحمال و انحفاض في قيمة زاوية الوضع للمسند و كذلك انخفاض قيمة معامل الإحتكاك.
لوحظ أيضا زيادة تمدد طبقة الزيت عند استخدام مسند ذو نفاذية متغيرة عن تلك التي تم الحصول عليها عند استخدام مسند ذو نفاذية منتظمة.
Abstract EN
Effect of non uniform permeability on the operational characteristics of finite width misaligned self lubricated journal bearing is investigated throughout this work.
A modified boundary conditions for the oil film pressure is obtained by applying integral momentum equation to the oil film region in the bearing clearance.
The performance characteristics of a misaligned self lubricated journal bearing with slenderness ratio of unity are obtained for various eccentricity ratios and misalignment angle.
The bearing permeability is changed in radial and circumferential directions.
Using self lubricated bearing with non – uniform permeability enhances the performance of such bearing.
An decreases in maximum pressure and load carrying capacity, attitude angle, and coefficient of friction.
Oil film extent increases with increasing the oil supply pressure.
