Mechanical design is a method of analyzing, calculating and designing the structure, motion form, working principle and lubrication method of mechanical products according to the usage requirements of the products, and applying these methods to the specific design process. The traditional mechanical design method, also known as the conventional mechanical design method, is a product design method that requires designers to manually retrieve data, calculate and draw, with long design cycles and low design quality. With the development of science and technology and the rapid upgrading of products, the traditional mechanical design method has been unable to meet the design requirements of mechanical designers, so the modern mechanical design method is proposed. Modern mechanical design method is the improvement and change of the traditional mechanical design method. It aims to develop and improve the design theory, improve product design methods, improve product quality and shorten the design cycle, including innovative design methods, system analysis design methods, optimization design methods, finite element analysis methods, reverse engineering design, etc. Next, let’s learn more about the difference between mechanical design and industrial design.
The mechanical design procedure of general mechanical equipment has the following stages.
1. The research stage of mechanical design. In the investigation stage, the technical and operational requirements of the mechanical equipment needed for mechanical design should be fully investigated and analyzed. Through the analysis, the function of mechanical equipment can be further clarified.
Second, the preliminary stage of the mechanical design program. The preliminary mechanical design of the program is not only to meet the needs of the mechanical equipment function and the direction of development of the machinery and equipment industry, but also to test the mechanical design of mechanical equipment development understanding and application of the “four new” ability. Mechanical preliminary design of the main steps are: to determine the working principle and basic structure of machinery and equipment, design the form of movement, design the main parts, drawing preliminary general assembly drawings and preliminary mechanical design.
Third, the final stage of mechanical design. Mechanical design stage is divided into three steps: first, the general assembly sketch and parts assembly sketch. According to the general assembly sketches and parts assembly sketches, the overall design of the product is carried out. In addition, in the mechanical design stage, the design should be modified according to the review comments, all parts should be designed, a new general mechanical design drawing should be drawn, and the mechanical design should be reviewed. In the final stage of mechanical design, all working drawings of the mechanical design are drawn. For large mechanical equipment, many mechanical designers need to work closely together, and the chief mechanical designer should pay close attention to the connection design of the connected parts. Compared with the mass production of machinery and equipment, it is necessary to carry out stereotyped mechanical design and consider the use of tooling design to improve product production efficiency and reduce costs.
4. The preparation stage of mechanical design documents: there are many kinds, including calculation instructions, operation instructions, standard parts, commonly used parts, breakdown of wearing parts, etc.
Systematic mechanical design method is a breakthrough of the traditional mechanical design method, changing the simple functional requirements that were set in stone in the past. Systematic mechanical design method makes the whole mechanical design method more systematic, informative and intelligent, and it can recover some lost data without losing data by managing user information or disabling some programs, so as to protect the interests of user system and the whole system.
