摘要

The mechanical behavior of the trachea in living organisms is critical to respiratory function. Utilizing these biological characteristics, this study investigates the design of conduct fabricated through 3D printing to replicate the stiffness and elasticity of the trachea for applications in medicine and industry. This project marks a significant advancement in developing efficient biologically inspired medical and industrial devices. Conducts are produced with 3D printing technology tailored to the specific requirements of each field. To examine the mechanical properties of these conducts numerical simulations were conducted using ABAQUS to analyze conduct movement under maximum simulated loads during a standard respiratory cycle. This analysis provides valuable insights into the conduct’s behavior under realistic conditions facilitating its practical application. Additionally, Design of Experiments (DOE) modeling was employed to evaluate stiffness and elasticity exploring the impact of various parameter combinations. This approach demonstrates a strong correlation between experimental results and DOE predictions supporting the performance and reliability of the manufactured conducts. A numerical compression modeling study was also conducted where forces determined by a DMA machine corroborated the experimental test results.
