The mechanical design is an important part of mechanical engineering, mechanical proction the first step, is to decide and mechanical properties of the main factors. The mechanical design efforts goal is: in all kinds of limited conditions (such as materials, processing ability, knowledge and calculation method and so on) make the best of mechanical design, namely make optimization design. Optimization design need comprehensive consideration, generally have many demands: best work performance, the lowest manufacturing costs and minimal size and weight, use the reliability, the lowest in cost and at least the pollution of the environment. These requirements are often conflicting, and between them the relative importance for mechanical types and different purposes of and different. The designer's task is according to the specific circumstances weigh weight, the overall consideration, which makes the design of mechanical have the best comprehensive technical and economic effect. In the past, the design optimization of the designer relies mainly on the knowledge, experience and vision. With the basic theory of mechanical engineering and value engineering, system analysis and so on the new development of the discipline of, the proction and use of technical and economic data material accumulation, and the popularization and application of the computer, optimization graally abandon subjective judgment and rely on scientific computing.热心网友 时间:2023-10-08 22:06
Mechanical design is an important part of mechanical engineering, mechanical proction of the first step is to determine the mechanical properties of the most important factor. Mechanical design efforts are: limited in a variety of conditions (such as materials, processing capacity, theoretical knowledge and computational tools, etc.) to design the best machinery, which make optimal design. Optimize the overall design needs to consider many of the requirements, generally: the best performance, lowest manufacturing cost, minimum size and weight, using the most reliable, low consumption and minimal environmental pollution. These requirements are often conflicting, and their relative importance between the use of machine types and vary. Designer's task is to weigh the severity of the situation-specific, integrated, so that the mechanical design has the best overall technical and economic effect. In the past, rely mainly on the designer to optimize the design of the knowledge, experience and vision. With the basic theory of mechanical engineering and value engineering, systems analysis and other new disciplines, develop, manufacture and use of technical and economic data in the accumulation of information, and promote the use of computers, optimization graally abandoning subjective judgments and rely on scientific computing.热心网友 时间:2023-10-08 22:07
