Modern machinery

Machinery is a combination of artificial physical components. There is a certain relative movement between the parts of the machine.

In addition to the features of a mechanism, a machine must also have a third feature that can replace human labor to complete useful mechanical work or convert mechanical energy, so the machine can convert mechanical energy or complete useful mechanical work. From the point of view of structure and movement, there is no difference between mechanism and machine.

Know modern machinery

  1. A machine is a combination of objects, and it is difficult to deform if force is applied to its various parts.
  2. These objects must realize mutual, single, prescribed movement.
  3. Transform the applied energy into the most useful form or into effective mechanical work.

The definition of mechanism and machine is derived from mechanical engineering and belongs to the most basic concept in modern mechanical principles. The modern concept of Chinese machinery is mostly derived from the word “machine” in Japanese.

The general term for all machines and institutions with a definite movement system. Such as: machine tools, tractors, etc.
Mechanical engineering is based on the theoretical basis of relevant natural sciences and technical sciences, combined with the technical experience accumulated in production practice, to study and solve the theoretical and practical problems in the development, design, manufacturing, installation, use and repair of various machinery. Applied disciplines.

The development of various engineering fields requires the corresponding development of mechanical engineering, and mechanical engineering provides 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 contributed to the establishment of power systems; the invention of locomotives led to the rise of railway engineering and railway business; the invention and progress of internal combustion engines, gas turbines, and rocket engines, as well as the successful development of aircraft and spacecraft. The rise of aviation and aerospace industry; the development of high-voltage equipment has led to the success of many new synthetic chemical projects and so on.

Mechanical engineering is the ability to obtain development momentum under the pressure of increasing demands in all aspects, and at the same time obtain the ability to improve and innovate from the progress of various disciplines and technologies.

Machinery is a simple device that can transfer energy and 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 machinery working for us around us.

The daily understanding of machinery is mechanical devices, that is, various machines and equipment.

From the perspective of mechanical profession: Machinery has a very important basic position.

Machinery is one of the five major elements (that is, people, capital, energy, materials and machinery) for production and services in modern society.

When Marx talked about industrial society, he talked about industrial society, especially large-scale industrial society, that is, the era of using machines to produce machines.

Regardless of the various physical devices that come into contact in life, such as electric lights, telephones, televisions, refrigerators, elevators, etc., they all contain the components of machinery, or are included in machinery in a broad sense. From the perspective of production, various Machine tools, automation equipment, airplanes, ships, Shen 5, Shen 6 and so on are indispensable for machinery.

Therefore, machinery is a foundation of modern society. If someone wants to say that agriculture is also the foundation, it is understandable. However, in modern society, machinery, as the foundation of the entire industry and engineering, can be considered without exaggeration as a big pillar of society.

Any modern industry and engineering field need to apply machinery, that is, people’s daily life and more and more various machinery are used, such as cars, bicycles, clocks, cameras, washing machines, refrigerators, air conditioners, vacuum cleaners and so on.
