What requirements should be met when designing a machine 5

1 2 What are the basic requirements that should be met when designing a machine? Answer: 1. Functional requirements to meet the predetermined working requirements of the machine, such as the motion form, speed, motion accuracy and smoothness of the working part of the machine, the power that needs to be transmitted, and some special requirements for use (such as high temperature, moisture-proof, etc.).

2. Safety and reliability requirements (1) Make the entire technical system and parts work normally without breakage, excessive deformation, excessive wear and loss of stability under the specified external load and specified working time. (2) It can realize the protection of operators and ensure personal safety and health. (3) The surrounding environment and people of the technical system will not cause harm and pollution, and at the same time, the adaptability of the machine to the environment should be ensured.

3. Economy In the whole product design cycle, we must consider the three aspects of product design, sales and manufacturing as a system engineering, use value engineering theory to guide product design, use materials correctly, and adopt reasonable structural size and process to reduce the cost of products. When designing mechanical systems and components, they should be standardized, generalized, and serialized as much as possible to improve design quality and reduce manufacturing costs. 4. Other requirements The mechanical system has a beautiful appearance and is easy to operate and maintain.

In addition, it must also be considered that some machinery has some special requirements for the design due to different working environments and requirements, such as food hygienic conditions, corrosion resistance, high-precision requirements, etc.

The design requirements that mechanical products should meet: use requirements, reliability requirements, economic and economic requirements, easy operation, work safety, beautiful appearance, and pollution reduction.

1. Requirements for use. Mechanical products should meet the user's requirements for the required functions, which is the most fundamental starting point of mechanical design.

2. Reliability requirements. Mechanical products should have the ability to complete the specified functions within the specified time under the specified conditions.

3. Economic requirements. The design, manufacturing, and use of mechanical products should be economical.

4. Easy to operate and safe to work. The operating system is simple and reliable, which is conducive to reducing the labor intensity of operators.

5. Beautiful appearance and reduce pollution. The shape of mechanical products directly affects the sales and competitiveness of products, and is a link that cannot be ignored in the current mechanical design, and noise is also an important criterion for reflecting the quality of machinery.

Machinery products refer to the finished products, semi-finished products, parts, components, assemblies and other specific products provided by machinery manufacturers to users or markets for production, sales and maintenance, which are the main body of the products of machinery manufacturing enterprises. Mechanical products have dusty design requirements in terms of use requirements, reliability requirements, economic requirements, convenient operation, work safety, beautiful appearance, and pollution reduction.

The design of mechanical products is an important part of machinery manufacturing enterprises, and the design determines the function, quality, life and quality of the product. The design of mechanical products should be designed according to the user's use requirements and economic requirements, and at the same time, the reliability, easy operation, work safety and beautiful appearance of the product should be considered.

The manufacturing, sales and maintenance of mechanical products need to be strictly controlled

The manufacturing of mechanical products is also an important part of machinery manufacturing enterprises. The manufacture of mechanical products should be manufactured in accordance with the design requirements to ensure the quality, accuracy and reliability of the products. The manufacturing of mechanical products includes the procurement of raw materials, the processing of parts, the assembly of components and the commissioning of products.

The sales and maintenance of mechanical products are also an important part of machinery manufacturing enterprises. The sales of mechanical products should take into account factors such as market demand and high quality, and at the same time provide good after-sales service. The maintenance of mechanical products should be timely, accurate and reliable to ensure the user's experience and safety.
