The master of the automatic door plays a crucial role in determining the strategic decision-making stage of key design factors, such as technical and economic indicators. When planning the overall design, several fundamental questions must be addressed: (1) Technical aspects: manufacturing productivity, precision, strength, stiffness, reliability, service life, operational performance, safety, and environmental impact. (2) Economic considerations: efficiency, cost-effectiveness, production costs, ease of maintenance, size, and weight. (3) Aesthetic elements: harmony with the surrounding environment, color coordination, and overall style. As an automated mechanical device, the automatic door must follow general machinery design principles. While it has specific requirements, its basic design content and principles must align with standard mechanical engineering practices. Design Considerations for Mechanical Parts (1) Ensuring proper function and avoiding failure is essential. Failure occurs when a component loses its intended functionality. The effectiveness of parts depends on material choice, working conditions, and stress levels. To ensure reliable operation, components must meet basic design criteria like strength, stiffness, stability, friction control, and thermal management. 1) Strength: Components that break or deform permanently during operation lack sufficient strength. This can lead to either complete failure (e.g., gear root fracture) or surface failure (e.g., tooth deformation). To enhance strength, high-strength materials, larger cross-sections, and treatments like heat or chemical processing are recommended. Most mechanical parts operate under variable stress, making fatigue the main cause of failure. Designers should consider stress concentration, surface finish, and environmental factors during the design phase. 2) Stiffness: Deformation during operation must stay within acceptable limits. Excessive deformation can affect performance, especially in load-bearing components like rotating doors or guide rails. Stiffness includes both overall deformation and contact surface stiffness. Increasing section size, moment of inertia, and support area helps improve stiffness. 3) Surface Damage: Corrosion, wear, and contact fatigue are common causes of surface damage. Using corrosion-resistant materials or protective coatings like anodizing or painting can help prevent this. 4) Environmental Effects: Parts must function properly under specific environmental conditions. For example, gears and bearings require lubrication, and extreme temperatures can reduce their load capacity. (2) Additional design requirements include: 1) Structural Processability: Parts should be easy to manufacture, assemble, and maintain. This involves considering the entire production process, from raw material to final assembly, while taking into account current production capabilities. 2) Economic Efficiency: Simplifying part designs, using cost-effective materials, and incorporating standard components can significantly reduce production and assembly costs. 3) Reliability: Reliability refers to the ability of a part to perform its function over time under specified conditions. Since failures can be random, improving reliability involves minimizing variability and ensuring regular maintenance and inspection.
