The designer should be responsible for the technical rationality

 Keep close contact with Mechanical Bearing 6900 practice and strive to cultivate the ability to solve practical engineering problems; force and failure analysis should be carried out according to the working conditions of parts and components, and design calculation formulas should be established according to functional requirements and design constraints. 2)

The complexity of design management in the design process. In the design process, the designer continuously enriches and perfects the design information of the product until the entire product design is completed. In order to adapt well to this job, mechanical designers must possess the following basic qualities: 1. 5., the general content and goals of each stage are shown in Figure 1-2. The production level of the machinery industry is one of the main indicators of the level of modeization of a country.gif[/img] Table 1-1 'Machine Examples §1-3' Concepts and Features of Mechanical Design 1.

High sense of responsibility and rigorous work style: The designer should be responsible for the technical rationality of the design and the design consequences, and should work meticulously. The functional structure diagrams of different machines are different, and even the total functional requirements are the same, the functional structure diagrams of different schemes can be designed.

Starting from market demand, through conception, planning, and decision-making, the functions, principle schemes, technical parameters and structure of mechanical products are determined, and the ideas are tued into reality. Sustainable development issues in mechanical design 1) The products designed should meet the goals of the national science and technology policy and the national science and technology development plan: to design competitive advanced products, you should also have a good understanding of the country's science and technology in different periods Policies and scientific and technological development plans; 2)

The designed products should meet the requirements of reducing environmental pollution caused by the three wastes; 3) The designed products should meet the safety and reliability requirements of the human-machine system; 4) The designed products should be conducive to improving productivity ; 5) Reasonable use of resources. A machine can have only one execution part, or it can decompose the functions of the machine into several execution parts
