Ask ChatGPT about the research

Our research includes the transmission mechanism of the wind turbine and the calculation of losses, such as loss of mechanical ventilation and friction loss and the loss of lubrication between the gear teeth design. Aims and access to high reliability work and thus obtain high efficiency and taking advantage of electronic programs, We observed that each type of previous losses have an impact on the overall loss of Gearbox, Depending on the working conditions, For example, at low speeds, loss of friction between the teeth is a great percentage of the total loss, And thus controls the overall efficiency of the transport system, while at high speeds noticed this low percentage of loss, while the loss of lubrication and ventilation rate rose.

Research summary
يتناول البحث تصميم آلية نقل الحركة لعنفة ريحية، وحساب الضياعات الميكانيكية مثل ضياع التهوية وضياع الاحتكاك وضياع التزييت بين أسنان المسننات بهدف تخفيضها وزيادة وثوقية العمل للحصول على مردود عالي. تم استخدام برامج إلكترونية لحساب تأثير كل نوع من الضياعات على الضياع الكلي لعلبة السرعة. أظهرت النتائج أن ضياع الاحتكاك بين الأسنان يشكل النسبة العظمى من الضياع الكلي عند السرعات المنخفضة، بينما يرتفع تأثير ضياعات التزييت والتهوية عند السرعات المرتفعة. تم تصميم علبة السرعة باستخدام لغة البرمجة (الماتلاب) لتأمين طاقة كهربائية لمنزل منعزل، وتم حساب مواصفات علبة السرعة وعرض النتائج في جداول. أظهرت الدراسة أن ضياع الطاقة بالاحتكاك يشكل أكثر من 85% من الضياع الكلي، وأن المردود الكلي يزداد مع زيادة سرعة الدوران. توصي الدراسة بتخفيض ضياع الاحتكاك في المرحلة الأولى وضياع التهوية والاحتكاك في المرحلتين الثانية والثالثة لزيادة مردود علبة السرعة.
Critical review
دراسة نقدية: يعتبر البحث ذو أهمية كبيرة في مجال تحسين كفاءة أنظمة نقل الحركة في العنفات الريحية. ومع ذلك، كان من الممكن أن يكون البحث أكثر شمولية إذا تم تضمين تحليل اقتصادي لتكاليف تنفيذ التوصيات المقترحة. كما أن استخدام لغة البرمجة (الماتلاب) قد يكون محدودًا بالنسبة لبعض الباحثين الذين قد لا يكون لديهم خلفية برمجية قوية. كان من الأفضل أيضًا تضمين دراسة مقارنة مع أنظمة نقل حركة أخرى لمعرفة مدى تفوق التصميم المقترح. على الرغم من ذلك، فإن البحث يقدم إسهامًا قيمًا في فهم وتحليل الضياعات الميكانيكية وتأثيرها على كفاءة أنظمة نقل الحركة.

This study treat the effect of the Suction method as a way of the boundary layer controlling in order to avoid or at least delay the boundary layer separation and to explain the effectiveness of this method in improving the aerodynamic performance of the Airfoils of the studied wind turbine blade and thus the possibility of obtaining better electrical output of the wind turbine, that is performance improving of wind turbines and obtains a better design.
This paper focuses on the estimation schemes of a viable position for timing belt drives where the position of the carriage (load) is to be determined via reference models receiving input from a position sensor attached to the actuator of the timin g belt. A detailed analysis of the transmission error sources is presented, and a number of relevant mathematical models is developed using a priori knowledge of the process. This paper demonstrates that such schemes are very effective when the drive system is not subjected to external loads and operating conditions do not change considerably i.e. ambient temperature, and belt tension.
reliance on new and renewable sources of energy has grown in order to obtain electric power without the use of traditional fossil fuel sources. And thus solve the problems of the global energy crisis and also maintain a clean environment, through the fight against the dangers of global warming and its negative results Wind power is considered as one of the most important of these alternative energies. We will work in this research in order to be able to control wind turbine with variable speed through pitch angle control in order to organize power and control the rotational speed in order to make the power ideal. Where we will be using a fuzzy controller to control pitch angle instead of the traditional controllers, which is expected to improve system response and provide ease in the application and modification and reduction in the cost. By reference study we came to the result showing that most previous studies in advanced wind energy systems have addressed to control wind turbine using conventional controllers from PI or PID type. Show we have the problem of the need to know the exact mathematical model of the system. Where traditional controllers of wind turbines that operate at variable speed are based on mathematical models which may be complex and non-linear and neglect often physical phenomena, for example, magnetic saturation which leads to complexity in the calculation and unexpected performance of the driven system. The proposed research aims to provide a complete study through modeling and simulation using the Matlab about the use of fuzzy controller to control the wind turbine where traditional controllers of type PI will be designed to control the pitch angle and to control the rotational speed and fuzzy PI controllers to control the pitch angle. Results will be get and discussed and conclusion will be extracted from them. Research Results showed that the fuzzy control improves transient state behavior, but the steady-state behavior is better controlled when we use PI controller. So and based on the result we got, the PI controller can't be replaced actually with the fuzzy controller.
As a result of the development of the use of reinforced Composites with fibers in practical applications continuously, research aims to study the effect of proportion piroxide additives to unsaturated polyester resin on the tensile properties of th e samples prepared from unsaturated polyester resin reinforced with glass fiber used in wind turbine blades manufacturing, and also studying the effect of for the application of heat treatment operations on the hardening of the unsaturated polyester and tensile properties after heat treatment process the application in order to improve the properties of these blades. Test samples were prepared containing ratios (1% - 1.5% - 2%) of methyl Etel ketone piroxide MEKP and test results showed that the best ratio at 1.5%. While the heat treatment results showed that the best values for tensile strength at break of the samples are treated to a time of / 48 hours /.
