Design principles for mechanical components
2025-07-25
Functionality and reliability
The parts need to meet the functional requirements of the equipment, such as gears that need to transmit specified torque and have low noise.
Optimize the structure through finite element analysis (FEA) to avoid stress concentration, such as using hollow structures to reduce weight and improve strength for aircraft engine blades.
Standardization and interchangeability
Prioritize the use of standard components such as ISO bolts and DIN bearings to reduce manufacturing costs and facilitate maintenance.
Modular design improves the universality of parts, such as the use of standardized servo motors for industrial robot joints.
Economy and Craftsmanship
Balancing performance and cost, such as forging instead of casting automotive engine connecting rods to improve fatigue life.
Simplify the processing technology, such as using stamping instead of machining to produce thin plate parts.
Environmental adaptability
Consider environmental factors such as working temperature and corrosiveness, such as using stainless steel or anti-corrosion coatings for marine equipment parts.
Lightweight design reduces energy consumption, such as using aluminum alloy instead of cast iron for the motor housing of new energy vehicles.
