Machinery parts is namely machine parts, it is basic components of machine.
Since the present of machine, the corresponding mechanical parts appear. But as also be a discipline, machinery parts separated from the mechanical structure and mechanics. With the development of mechanical industry, new design theory and method, new materials, new technology all appear one after another, then machinery parts entered a new stage of development. Theories such as finite element method and fracture mechanics, elastic hydrodynamic pressure lubrication, optimization design, reliability design, computer aided design (CAD), entity modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology has been gradually used in the research and design of machinery parts. Better combination of a variety of disciplines, combination of macro and micro to search new principle and structure, more dynamic and precise design, more efficient use of the electronic computer, the further development of design theory and method, is the important trend in the development of the discipline.

Yesterday, the Ministry of Industry and Information Technology website announced the "12th Five-Year Plan for Development of High-end Equipment Manufacturing Industry" (hereinafter referred to as "Planning"). The "Planning" proposes that the key directions for the development of high-end equipment manufacturing at this stage include aviation equipment, satellites and applications, rail transportation equipment, marine engineering equipment, and intelligent manufacturing equipment.
Luo Jun, secretary general of the Asia Manufacturing Industry Association, said in an interview with the Morning Post reporter yesterday that the five industries proposed for key development this time are the shortcomings for the development of China's high-end equipment manufacturing industry. For example, marine engineering equipment is very weak. The smart manufacturing equipment is the direction of future industrial development. The United States has developed rapidly. Now China is only at the initial stage.
According to the “Planningâ€, by 2015, China’s high-end equipment manufacturing sales revenue will exceed 6 trillion yuan, its share in the equipment manufacturing industry will increase to 15%, the industrial added value rate will reach 28%, and the international market share will increase significantly.
By 2020, the proportion of high-end equipment manufacturing industry sales revenue in the equipment manufacturing industry will increase to 25%, the industrial value-added rate will increase by 2% from the end of the “Twelfth Five-Year Planâ€, and the high-end equipment manufacturing industry will be nurtured as the pillar of the national economy. industry.
According to the "planning" data, in 2010, high-end equipment manufacturing industry achieved sales revenue of about 1.6 trillion yuan, accounting for about 8% of the sales revenue of the equipment manufacturing industry.
Luo Jun believes that the current development of high-end equipment manufacturing requires calm, can not engage in low-level redundant construction, resulting in a large number of industrial surplus. In addition, we must also pay attention to some projects that do not meet the requirements of the new industry.
In terms of specific goals, the "Plan" proposed that the focus will be on speeding up the development of large passenger aircraft, regional aircraft, general aviation aircraft and aerospace equipment. Large passenger aircraft will make the first flight, jet regional aircraft will be successfully developed, and 100 branch aircraft will be sold annually. Sustainable development capacity of the aviation industry system.
Among them, the large passenger aircrafts, starting with 150 seats with a large market demand, have developed 150-class C919 single-aisle trunk aircraft with international competitiveness, and gradually formed their industrialization capabilities. Conduct future model study.
In terms of regional aircraft, the development of ARJ21-700 turbofan feeder aircraft has been accelerated, and model certifications and production licenses of Chinese airworthiness authorities have been obtained before and after 2012, resulting in industrialization capabilities and batch delivery; in 2013, foreign airworthiness certificates were obtained.
In the rail transit equipment industry, the "planning" revealed that it is expected that the demand for EMUs will be around 1,000 columns during the "12th Five-Year Plan" period.
"Planning" proposes that by 2015, the annual output value of the rail transit equipment industry will exceed 400 billion yuan, and the products will meet the needs of China's rail transit construction.
As one of China's seven strategic emerging industries, high-end equipment [5658.13 0.24%] has been finalized in terms of its manufacturing goals and direction.
