Optimization research of structural parameters of cylindrical hinges

Introduction

Structural hinges are widely used in various engineering fields due to their excellent energy absorption and damping capacity. Cylindrical hinges, in particular, have been extensively studied for their unique characteristics. However, the optimization of structural parameters of cylindrical hinges is still a challenging task. This paper aims to present a comprehensive review of the optimization research of structural parameters of cylindrical hinges.

Structural Parameters of Cylindrical Hinges

The structural parameters of cylindrical hinges include the hinge length, hinge diameter, wall thickness, and material properties. These parameters have a significant impact on the mechanical properties of cylindrical hinges. The optimization of these parameters can enhance the energy absorption and damping capacity of cylindrical hinges. The following are the key factors that affect the optimization of structural parameters of cylindrical hinges:

1. The hinge length affects the deformation capacity of the hinge. A longer hinge can absorb more energy but may result in a larger deformation.
2. The hinge diameter affects the stiffness of the hinge. A larger diameter can increase the stiffness and energy absorption capacity of the hinge.
3. The wall thickness affects the strength and weight of the hinge. A thicker wall can increase the strength but may result in a heavier hinge.
4. The material properties affect the energy absorption and damping capacity of the hinge. The selection of appropriate material properties can enhance the mechanical properties of the hinge.

Optimization Methods of Structural Parameters of Cylindrical Hinges

Various optimization methods have been proposed to optimize the structural parameters of cylindrical hinges. The following are the commonly used optimization methods:

1. Mathematical modeling and simulation: Mathematical models and simulations can be used to optimize the structural parameters of cylindrical hinges. Finite element analysis (FEA) is a commonly used simulation method.
2. Experimental testing: Experimental testing can be used to optimize the structural parameters of cylindrical hinges. The mechanical properties of the hinge can be tested under different loading conditions.
3. Multi-objective optimization: Multi-objective optimization can be used to optimize the structural parameters of cylindrical hinges. This method can optimize multiple objectives simultaneously, such as energy absorption, deformation, and weight.
