Design principles and precautions for connecting pairs of composite components

The design principles and precautions for connecting pairs of assembly components can be summarized as follows:

Design principles

Functional principle:

Ensure that the connecting pair can meet the expected functional requirements for connecting, supporting, or transmitting loads.

According to the application environment, choose appropriate connection methods and structural types (such as detachable connection pairs, non detachable connection pairs, dynamic connection pairs, or fixed connection pairs).

Principles of strength and stability:

The design should ensure that the connecting pair has sufficient strength and stability to withstand the expected loads and impacts.

Consider performance indicators such as tensile strength and yield strength of materials, as well as the structural design of connecting pairs (such as bolt diameter, pitch, number of washers, etc.).

Principle of Processability:

Choose materials that are easy to process and manufacture to reduce production costs and improve production efficiency.

Consider the processing performance of materials, such as cutting, forming, heat treatment, etc.

Corrosion resistance principle:

Select materials with sufficient corrosion resistance based on the application environment.

For connection pairs that require long-term exposure to humid and corrosive environments, corrosion-resistant materials such as stainless steel and titanium alloy should be considered.

Economic principle:

On the premise of meeting the requirements of functionality, strength, and stability, try to choose materials and design solutions with lower costs.

Taking into account factors such as material costs, processing costs, and maintenance costs, conduct a comprehensive consideration.

matters needing attention

Material selection:

Select appropriate materials based on the application environment and requirements.

Consider factors such as material strength, corrosion resistance, and processability.

Structural design:

Ensure that the structural design of the connecting pair is reasonable, avoiding stress concentration and fatigue failure.

Consider the convenience of assembly and disassembly of the connecting pair, as well as the convenience of maintenance.

Heat treatment and surface treatment:

Heat treat the connecting pair as needed to improve its strength and wear resistance.

Consider surface treatment of the connecting pair (such as spraying, coating, etc.) to improve its corrosion resistance and aesthetics.

Quality inspection and acceptance:

Conduct quality inspection on the produced connecting pairs to ensure they meet design requirements and quality standards.

During acceptance, the dimensional accuracy, surface quality, material properties, and other indicators of the connecting pair should be checked.

Maintenance and upkeep:

Regularly inspect and maintain the connecting pair to ensure it is in good working condition.

For problematic connecting pairs, they should be repaired or replaced in a timely manner.

By following the above design principles and precautions, it can be ensured that the design of the connecting pair of the assembly is reasonable, stable in performance, economical and practical, and meets the needs of practical applications.
