Applications of Disc Spring Washers in Mechanical Engineering

1. Automotive Suspension Systems
   Disc spring washers are widely used in automotive suspension systems to provide high elasticity and stability. For example, Mazda's "SEB Butterfly Imitation Rear Suspension Structure" employs a variable-section butterfly wing design, significantly enhancing the stiffness and toughness of the suspension system. This design reduces the impact of steering on suspension stroke, thereby improving vehicle handling performance.
2. High-End Mechanical Manufacturing
   In high-end mechanical manufacturing, disc spring washers are used in equipment subjected to high stress. For instance, Professor Liu Cheng's team at Yangzhou University's School of Mechanical Engineering developed high-performance spring steel disc spring washers with hardness and fatigue life far exceeding traditional products. These washers are suitable for heavy-load applications in aerospace and marine equipment.
3. Medical Devices
   Disc spring washers play a crucial role in medical devices. For example, the disc spring washers produced by Dongguan Du's Chengfa Precision Spring Co., Ltd., are used in precision components of medical devices, such as the multi-strand flexible drive shafts in OCT/IVUS imaging equipment. This application highlights their high precision and reliability.
4. Construction and Industrial Equipment
   In construction and industrial equipment, disc spring washers are used to provide cushioning and preload. For example, Kunming Chunying developed micro-deformation leaf springs that have improved production processes for applications in the construction market, opening up new sales channels.
5. Aerospace Industry
   Disc spring washers are used in critical components of aerospace applications for connection and cushioning. For example, the anti-deformation technology for shielded spring washers developed by Sun Guangcheng's team has successfully solved the industry's assembly deformation problem. This technology has been applied to the supporting products of China's heavy-lift carrier rockets.
6. Mechanical Machining
   In mechanical machining, disc spring washers are used to enhance the stability and precision of equipment. For example, Taiyuan Heavy Industry Group developed a CNC machining simulation platform that optimizes the manufacturing process. This ensures the machining accuracy and quality of disc spring washers, significantly improving production efficiency.
7. Automotive Engine Components
   Disc spring washers are used in automotive engine components to provide high reliability and fatigue resistance. For example, Fangda Special Steel developed 2000MPa high-strength spring flat steel for manufacturing high-stress steel plate springs. This material significantly improves the smoothness of vehicle travel and ride comfort.
