Abstract: Under the current rapid development of science and technology, social productivity has increased,and production efficiency has greatly improved. Under the development of modern industrial technology innovation, machinery and equipment are also facing challenges and opportunities. Modern mechanical design is more complex and has certain comprehensive characteristics. The main content involves disciplines such as mechanical principles and material structure. There is a strong connection between theoretical knowledge and practical applications. Under the current development of informatization and intelligent construction, human life and production activities increase the demand for machinery and equipment, and it is of great significance to carry out innovative design and research. The article expounds the characteristics of modern machinery and the process of mechanical design, analyzes and explores the requirements, principles and innovative ideas of equipment and machinery, which can promote the combination of design and innovation, keep up with the development of the times, and provide eff ective support for the machinery industry.
