Bozhanova is a unique publication that will become an indispensable assistant for specialists in the field of mechanical engineering, students and teachers of technical universities, as well as anyone interested in modern design technologies. This work combines theoretical foundations and practical aspects of design, which makes it relevant and useful for both experienced engineers and beginners in this field. In their book, the authors immerse the reader in the world of designing construction and road machines, revealing the key aspects that need to be taken into account at every stage of the creation of technology. The book covers a wide range of topics: from the basics of design and material selection to modern modeling and testing methods. Readers will be able to learn about how to properly organize the design process, what technologies and tools to use, and how to optimize design solutions to achieve maximum efficiency and safety. For whom is this book intended? First of all, it will be of interest to students and graduate students of technical specialties who seek to deepen their knowledge in the field of machine design . It will also be useful to practicing engineers working in the construction and road industries who want to update their knowledge of modern methods and approaches to design. In addition, the book can attract the attention of managers and project managers interested in optimizing the processes of development and implementation of new technologies. One of the main topics raised in the book is the importance of integrating theory and practice. The authors emphasize that successful design is impossible without a deep understanding of both technical and economic aspects. The book offers readers not only theoretical knowledge, but also practical recommendations, which makes it especially valuable for practical application. In this context, it is worth noting that the authors pay attention to the environmental aspects of design, which is a topical topic in the modern world, where sustainable development and environmental care come to the fore. The style of writing the book is clear and accessible, which makes it easy to perceive even the most complex concepts. The authors use many illustrations, diagrams and examples, which makes the material more clear and understandable. This is especially important for readers who may not be familiar with some technical terms or concepts. Thanks to this, the book becomes not only a textbook, but also a fascinating reading that can be of interest even to those who are simply interested in mechanical engineering. A. A. Bozhanov and his team of authors are professionals with rich experience in the field of design and engineering.
