Introduction
1. Torque hinges are widely used in various fields, such as automotive, aerospace, and medical equipment, to provide rotational motion with a specific torque value.
2. The structural optimization and lightweight design of torque hinges have become a hot research topic in recent years.
3. The purpose of this article is to review the latest research progress on the structural optimization and lightweight design methods of torque hinges.
Structural Optimization Methods
4. Finite element analysis (FEA) is the most commonly used method for structural optimization of torque hinges.
5. Topology optimization, which can automatically generate the optimal material distribution of a structure, has been applied to the design of torque hinges.
6. Multi-objective optimization, which simultaneously considers multiple design objectives, such as weight reduction and stress minimization, has been proposed for the design of torque hinges.
7. These optimization methods have been proved to be effective in improving the performance of torque hinges, such as reducing weight, increasing stiffness, and improving fatigue life.
Lightweight Design Methods
8. Lightweight design is an important aspect of torque hinge design, which can reduce the weight of the whole system and improve the energy efficiency.
9. Material selection is a key factor in lightweight design, and lightweight materials such as aluminum alloys and composite materials have been widely used in torque hinge design.
10. Additive manufacturing, which can produce complex and lightweight structures, has been applied to the fabrication of torque hinges.
11. The combination of topology optimization and additive manufacturing has been proposed for the design and fabrication of lightweight torque hinges.
12. These lightweight design methods can significantly reduce the weight of torque hinges while maintaining or even improving their performance.
