Driving cycle is commonly known as the relationship and a series of speed-time profile. The study on this discipline aids vehicle manufacturers in construction, environmentalists studying environment quality proportion with emissions traffic engineers to further investigate behaviour drivers road conditions which assist automotive industry better energy efficient productions. In order develop p...
In the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. According to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. On the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. In the primary stage of th...
The reduction in vehicle exhaust emissions achieved in the last two decades is offset by the growth in traffic, as well as by changes in the composition of emitted pollutants. The present investigation illustrates the emissions of in-use gasoline and diesel passenger cars using the official European driving cycle and the ARTEMIS real-world driving cycle. It was observed that some of the vehicle...
مهندسان در طراحی های بزرگ و پیچیده، قبل از ساخت نمونه فیزیکی و برآورد هزینه و زمان ساخت آن احتیاج به شبیه سازی کامپیوتری سخت افزار دارند. از طرفی سرعت شبیه سازهای متداول برای حجم بزرگ مدار بسیار کند می شود و این به دلیل محاسبات زیادی است که برای بدست آوردن اطلاعات ریز زمانی مدار انجام می شود. اما در بسیاری از موارد یک طراح احتیاج به دیدن درستی عملکرد طرح خود دارد و نه اطلاعات ریز زمانی آن. در ا...
در این پایان نامه خصوصیات کلی شبیه سازی cycle-based معرفی شده و نحوه انجام شبیه سازی cycle-based در سطح گیت و سطح انتقال ثبات مورد بررسی موشکافانه قرار گرفته است . در این پایان نامه همچنین محدودیتهای شبیه سازی cycle-based معرفی شده و راه حلهایی برای این مشکلات ارائه شده است . به موازات این پایان نامه و برای اثبات صحت نظریه های مطرح شده و راه حلهای ارائه شده در آن، یک شبیه ساز cycle-based برای ز...
A numerical investigation of the double-effect adsorption refrigeration cycle is examined in this manuscript. The proposed cycle is based on the cascading adsorption cycle, where condensation heat that is produced in the top cycle is utilized as the driving heat source for the bottom cycle. The results show that the double-effect cycle produces a higher coefficient of performance (COP) as compa...
Increasing the demand for electric vehicles, makes the manufactures to concentrate on the research of new energy storage devices, electro motors, and power electronic devices. The main subject in designing an electric motorcycle with four-phase AFPM and its full wave converter is to select suitable energy storage system and add on turbo-acceleration mechanism. Choosing the suitable energy stora...
In this paper a novel four-leg interleaved DC-DC boost converter is proposed which is well suitable for fuel cell vehicles (FCV) application. The voltage stress of two switches of this converter is half of the conventional interleaved converters. Therefore, smaller and cheaper switches can be utilized. Also "on" state duration of the two of four switches are reduced in comparison with...
