High-voltage cable terminal lead seals may develop defects such as holes, cracks, or delamination due to substandard installation quality or external forces during operation. Owing to the large curvature of the lead seal surface, using conventional ultrasonic probes for direct contact with the surface results in low efficiency in detecting lead seal defects and yields a low signal-to-noise ratio for defect echo signals. To address the ineffective detection of lead seal defects, a non-destructive detection method based on ultrasonic phased array flexible water bag coupling is proposed. This met ..read more

Lane-keeping systems are a major part of advanced driver assistance systems (ADAS). Existing lane detection algorithms are based on either Computer Vision (CV) models or deep learning techniques which are often vulnerable to unfamiliar routes, lane marking conditions, night-time driving, weather conditions, etc. To improve lane detection accuracy under various challenging conditions, we propose a framework that utilizes several lane detection models with different features to obtain a robust algorithm. The proposed Multiple Model Adaptive Estimation (MMAE) algorithm works with two cameras, one ..read more

In times of global climate change, the reduction in friction in technical applications is of crucial significance. Surface textures are one possibility for reducing friction in lubricated contacts. To provide a deeper understanding of the effects of surface textures on the tribological performance, this study analyzes wedge-shaped, textured lubrication gaps using a novel test rig with an in situ lubrication gap height measurement. Using this experimental pin-on-disc setup, chevron-shaped and cylindrical textures with two different heights (ht = 10 and 50 µm) were tested under full-film lu ..read more

IntroductionAccurate speed measurement is crucial for improving the efficiency and reliability of the transmission system in hydraulic excavators. However, traditional M and T methods have their own limitations in speed measurement, especially in terms of measurement accuracy over a wide speed range.MethodsA M/T velocity measurement algorithm combining the advantages of M and T methods was proposed to address this issue, and dynamic errors were obtained. The kinetic energy theorem can also be used.ResultsThe experimental results show that under the normal load of unit tooth width F, the change ..read more

BackgroundIn the power system, the identification of the health status of the transmission tower is a daily task that must be performed. In addition, bolt loosening is a common damage mode affecting the main materials of transmission towers. When bolt loosening occurs, it weakens the bearing capacity of the transmission tower. If not detected and addressed in a timely manner, serious adverse events, such as tower collapse, may occur which will endanger the normal operation of the power system.MethodsBased on this, in order to ensure the normal operation of the transmission tower and improve th ..read more

This paper experimentally assess the energy consumption of a laboratory knuckle boom crane utilizing two proposed two-motor-two-pump (2M2P) motor-controlled hydraulic cylinders (MCC) in comparison to two conventional valve-controlled hydraulic cylinders (VCC). Experimental results demonstrate that using the motor-controlled crane instead of the valve-controlled crane results in 60%–64% total energy savings. In conclusion, this study highlights the practical suitability of the 2M2P MCCs for real-world applications, showcasing their enhanced energy efficiency compared to conventional VCCs ..read more

In factory automation applications, the embedded control system components are often available as off-the-shelf products, while the mechanical components and environment in which they will work are still under development. Thus, the need arises to test control systems without the final assembly. This paper introduces a hardware-in-the-loop (HIL) virtual environment for control system testing, design planning, and operator training. Controller hardware and software are configured as in the actual application, whereas electro-mechanical components are virtually constructed using Unreal Engine 5 ..read more
