Distribute the reliability indexes required by the system to each component unit of the system reasonably, so as to define the reliability design requirements of each component unit, so as to ensure it in the process of unit design, manufacture, test and acceptance. In order to ensure the reliability of mechanical manufacturing equipment, it is necessary to accumulate fault data based on the existing reliability technology and a large number of similar products in enterprises.

Based on the results of failure mode impact hazard analysis, mechanical manufacturing equipment is designed and developed according to the requirements of product reliability design criteria, reliability design checklist and reliability comprehensive design method. Fully consider the influence of environment, maintenance, transportation, stress, materials, temperature, wear and aging and other links and factors on product reliability.

Verify and check the design scheme of the prototype in detail, and try to eliminate the possible hidden dangers of the prototype in the design stage. Based on the analysis results, the mechanical manufacturing equipment is designed and developed according to the requirements of product reliability design criteria, reliability design checklist and reliability comprehensive design method.

Considering the influence of environment, maintenance, transportation, stress, material, temperature, wear and aging on product reliability, the design scheme of the prototype is verified and checked in detail, and the possible hidden dangers of the prototype are eliminated in the design stage as much as possible.

System design principles:

1, the system is an organic whole. Therefore, in the system design, we should consider from the perspective of the whole system, so that the system has unified information code, unified data organization method and unified design norms and standards, thus improving the design quality of the system.

2. The principle of economy refers to reducing the system cost as much as possible under the premise of meeting the system requirements. On the one hand, we should not blindly pursue technological progress in system hardware investment, but should take meeting the system requirements as the premise. On the other hand, the system design should avoid unnecessary complexity and each module should be as simple as possible.

3. Reliability is not only an important index to evaluate the quality of system design, but also the basic starting point of system design. Only when the designed system is safe and reliable can it play its due role in practice.
