Background technique

Machinery refers to the general term for machines and mechanisms. Machinery is a tool device that can help people reduce the difficulty of work or save labor. Items such as chopsticks, brooms, and tweezers can all be called machines, and they are simple machines. A complex machine is composed of two or more simple machines. These more complex machines are usually called machines. From the point of view of structure and motion, there is no difference between a mechanism and a machine, and it is generally called a machine. Mechanical engineering is based on the relevant natural science and technical science as the theoretical basis, combined with the technical experience accumulated in production practice, to study and solve the theoretical and practical problems in the development, design, manufacture, installation, use and repair of various machinery. Applied disciplines. The development of various engineering fields requires the corresponding development of mechanical engineering, and requires mechanical engineering to provide the necessary machinery. The invention and improvement of certain machinery will lead to the emergence and development of new engineering technologies and new industries. For example, the successful manufacture of large-scale power machinery led to the establishment of electric power systems; the invention of locomotives led to the rise of railway engineering and the railway industry; the invention and progress of internal combustion engines, gas turbines, rocket engines, etc., as well as the successful development of aircraft and spacecraft led to The rise of aviation and aerospace; the development of high-pressure equipment has led to the success of many new synthetic chemical engineering and so on. Mechanical engineering is the ability to gain momentum under the pressure of ever-increasing demands on all fronts, while at the same time gaining the ability to improve and innovate from advances in various disciplines and technologies. Mechanisms are simple devices that transfer energy, force, from one place to another. It can change the shape and structure of objects to create new objects. In life, there are countless different kinds of machines around us doing work for us. The daily understanding of machinery is mechanical devices, that is, various machines and instruments. From the perspective of mechanical profession: machinery has a very important basic position. Machinery is one of the five elements (namely people, capital, energy, materials and machinery) for production and service in modern society. When Marx talked about industrial society, he meant industrial society, especially large-scale industrial society, that is, the era in which machines were used to produce machines. Regardless of the various physical devices that come into contact with in life, such as electric lights, telephones, televisions, refrigerators, elevators, etc., all contain machine components, or are included in machinery in a broad sense. From the perspective of production, various Machine tools, automation equipment, airplanes, ships, Shenzhou V, Shenzhou VI, etc., are all inseparable from machinery.
