Threaded connection loosening impairs operational safety, yet research on the mechanical mechanisms of anti-loosening is limited. This study developed a 2D axisymmetric finite element model in ABAQUS for standard, wedge-shaped ...

Multi-tooth difference cycloidal drives offer significant advantages for high torque density, efficiency and bandwidth applications like humanoid and quadruped robots due to their high load capacity and impact resistance. ...

To ensure the reliable operation and longevity of electronic devices, an effective cooling system is essential. This study numerically investigates the thermal-hydraulic performance of a pin-fin heat sink with secondary ...

An onboard compressor has been proposed to mitigate the Kantrowitz limit in Hyperloop systems, but directly resolving the internal compressor flow with conventional CFD is inefficient for iterative design. This study solves ...

Unsteady flow phenomena, such as von Karman vortex shedding at the trailing edge of Francis turbine runner blades, can induce pressure fluctuations, acoustic emissions, and structural vibrations, thereby compromising ...

Spray uniformity is a critical factor in the efficiency of wet etching processes. This study employs a particle-based method to simulate spray behavior and evaluates pressure uniformity on the surface of a flexible printed ...

Reliability analysis methods include traditional approaches, such as the first-order and second-order reliability methods and Monte Carlo simulation, as well as integration-based techniques like the intersection area ...

Rotating machinery systems generate substantial underutilized mechanical energy, yet conventional energy harvesters exhibit low efficiency and reliability in low-frequency rotational environments. Triboelectric nanogenerators ...

Present research, production of high-performance and sustainable poly (lactic acid) (PLA) composite that integrated with short kenaf fibers (3-4 mm) and 3 % titanium dioxide (TiO2) nanoparticles, through compression moulding ...

This study presents a rapid method to identify the yield stress (σy) and the work hardening exponent (n) which define the work hardening behavior of metallic materials using spherical instrumented indentation. The advantage ...
