Farm Machinery Design Principles And Problems 1 E

The book will serve as a useful design resource and as a practice kit to the agricultural engineering graduates, post graduates in farm power and machinery and for the students appearing for various competitive exams such as ARS, NET, GATE, JRF/SRF etc. The technology & improved designs of farm equipment and technical know how associated with it, is going to the quite useful to establish techno-economic viability for the staff engaged in R&D in farm machinery. This will also be quite useful reference book for the design engineers engaged in design and development of improved machinery in the modern agricultural mechanization. This is the first text book of its kind to address systematically the design prob elms involved in farm machinery. It offers comprehensive coverage of design principles and practices

In the branch of Agricultural Engineering, especially in Farm Machinery and Power sector, there is a need for a book exclusively dealing with various concepts and their applications in transparent and clear manner. So, an effort has been made to prepare this book entitled "Concepts of Farm Machinery and Power" to meet the demand of students, teachers, RS. The book will be useful immensely to the students preparing for GATE examination in AG papers and also for JRF, ARS, IFS examinations. The chapters of the book deals with conceptual analysis of farm machineries, which are confusing and difficult to understand. It is expected that the theoretical as well as numerical analysis of this book will sharpenthe ingenious power of the readers and help them to solve problemsquickly. Moreover, many problems are solved in different ways, which will help the readers in understanding and applying the concepts properly. I am extremely grateful to my teachers Dr. Subrata Karmakar, Associate Professor, Dept. of Farm Machinery and Power, Bidhan Chandra Krishi Viswavidyalaya; Prof. Partha Sarathi Chattopadhaya, Professor, Dept. of Farm Machinery and Power, Bidhan Chandra Krishi Viswavidyalaya; Er. Ravi Reddy, Senior Technician, CFMTTI, Budni, M.P., and my B. Tech friends for their encouragement and kind cooperation. Sagacious suggestions and discrete criticism are welcome to improve the book further, so that it becomes more relevant and more beneficial to the readers in real terms. Finally, I envisage this attempt as an important step in removing hurdles in the path of popularization of Agricultural Engineering. I hope that it will fire imaginations and ability of many Agricultural Engineers in the profession to produce such innovative works in future. “Agricultural Engineering— galvanizing agriculture”.

This textbook offers a comprehensive review of tractor design fundamentals. Discussing more than hundred problems and including about six hundred international references, it offers a unique resource to advanced undergraduate and graduate students, researchers and also practical engineers, managers, test engineers, consultants and even old-timer fans. Tractors are the most important pieces of agricultural mechanization, hence a key factor of feeding the world. In order to address the educational needs of both less and more developed countries, the author included fundamentals of simple but proved designs for tractors with moderate technical levels, along with extensive information concerning modern, premium tractors. The broad technical content has been structured according to five technology levels, addressing all components. Relevant ISO standards are considered in all chapters. The book covers historical highlights, tractor project management (including cost management), traction mechanics, tires (including inflation control), belt ground drives, and ride dynamics. Further topics are: chassis design, diesel engines (with emission limits and installation instructions), all important types of transmissions, topics in machine element design, and human factors (health, safety, comfort). Moreover, the content covers tractor-implement management systems, in particular ISOBUS automation and hydraulic systems. Cumulative damage fundamentals and tractor load spectra are described and implemented for dimensioning and design verification. Fundamentals of energy efficiency are discussed for single tractor components and solutions to reduce the tractor CO2 footprint are suggested.
