“…Modern engineering already depends on numerical modeling. Among the various methods of numerical modeling that can be used in modern engineering, the most common is the FE method due to its universal nature and the relatively simple preparation of models [20]. Numerical modeling methods can directly calculate the acceleration, displacement, and stress response of a structure under continuous dynamic loading, and can also effectively simulate crack growth under dynamic loading conditions in continuous media in the field of computational fracture mechanics (CFM) [21].…”

Based on an actual ultra-high voltage (UHV) substation, a finite element (FE) model for a high-voltage (HV) bushing, arrester, and down lead transmission line (DLTL) system was built using ANSYS software. The dynamic responses of the system under different seismic intensities were analyzed and compared with those of the corresponding single bushing and arrester. On this basis, the coupling vibration influence of the upper DLTL on the responses of the HV bushing and arrester is discussed. The results indicate that the DLTL adversely affects the responses of the HV bushing and arrester under seismic loading. As the seismic intensity increases, the structural displacements at the top of the HV bushing and arrester increase, accompanied by a reduction in the geometric length redundancy of the DLTL, resulting in a mutual pulling effect between the HV bushing and the arrester and the quick amplification of their respective dynamic responses in a nonlinear form. Under the action of an earthquake with a peak ground acceleration (PGA) of 0.4 g, the maximum stresses at the roots of the HV bushing and the arrester in the system separately increase by approximately 13.02% and 7.80% compared to the corresponding single HV bushing and the arrester. Overall, a geometric length redundancy of at least 200 mm in the DLTL in engineering design is recommended.

“…Biomechatronic devices, including robotic arms place a unique set of demands on the materials used in their construction (Mick et al, 2019). Mechanical characteristics such as flexural strength, tensile properties, compressive and wear resistance are highly important in determining the performance and durability of these applications (Krawczuk and Palacz, 2021;Andersson and Björsell, 2022;Witte, 2022). Robotic arms, for instance, rely heavily on bending and flexing to function effectively, directly influencing their lifting capacity and precision (Kramberger et al, 2017).…”

Advancements in materials science and 3D printing technologies have opened up new avenues for developing low-cost robotic grippers with high-performance capabilities, making them suitable for various biomechatronic applications. In this research, it has been explored the utilization of high-performance polymer materials, such as Polyetherketoneketone (PEKK), Polyethylene Terephthalate Glycol (PET-G) and MED 857 (DraftWhite), in the designing and developing of customized robotic grippers. The primary focus of made analyses was oriented on materials characterization, both experimentally and analytically. Computer-Aided Engineering (CAE) methods were employed to simulate bending experiments, allowing for a comprehensive analysis of the mechanical behavior of the selected materials. These simulations were validated through physical bending experiments using samples fabricated via 3D printing technologies, including Fused Filament Fabrication (FFF) for PET-G and PEKK, as well as Jetted Photopolymer (PolyJet) technology employing UV Resin for MED 857. The findings of this research provided advantages of utilizing advanced materials like PEKK in low-cost robotic grippers for biomechatronic applications. The experimental and analytical approaches offer valuable insights into material selection, design optimization, and the development of cost-effective high-performing robotic systems with a wide range of applications in the field of biomechatronics.

A Swing arm is a mechanical device that connects the rear wheel of the motorcycle to its body, allowing it to pivot vertically. It holds the rear axle firmly while pivoting to absorb bumps and suspension loads induced by acceleration and braking. Swing arm can be single or double-sided and has appeared in a variety of geometries. The original version consists of a pair of parallel pipes holding the rear axle at one end and pivoting at the other. A shock absorber is mounted just before the rear axle and attached to the frame, below the seat rail. The primary concern is to design a lightweight swing arm that can replace conventional motorcycle swing arm design, which consists of tubular sheet metal structure throughout the swing arm neglecting the stress-induced at various positions along the length of the swing arm, i.e. (from pivots to axle blocks). The vehicle selected for this project is Yamaha FZ-S V2. The material chosen for the swing arm are Al 6061, Al 6061 T6, and Al 7075. This project uses an iterative design method called Generative design to design a lightweight swing arm without compromising the mechanical properties and performance of its counterpart. Analysis of the part will be carried forward using static Analysis comprising various load cases and extreme load conditions. The whole design and analysis process is carried forward using Autodesk Fusion 360. This swing arm design involved economic utilization of material as it reflects the in the analysis through induced stresses.
