Special Issue Information

Dear Colleagues,

Ever since the term "tribology" was introduced in 1966, this field has evolved and given rise to various new domains of study, including nanotribology, biotribology, ecotribology, biomimetic tribology, and more. However, a significant challenge in the realm of surface engineering and tribology persists. While there exists a wealth of data concerning the surface characteristics of diverse materials, systems, and engineering components, this interdisciplinary field heavily relies on empirical methods. Despite numerous attempts to formulate tribological laws and rules, the discipline often lacks derivation from physical or chemical first principles. Consequently, tribology remains a data-driven inductive science.

In addressing this challenge, there has recently been the emergence of a new subfield within tribology known as "Triboinformatics". This development has been made possible by the latest advancements in the field of informatics, particularly artificial intelligence and machine learning. Informatics leverages digital technology's potential to transform data and information into knowledge. It utilizes inductive statistics to deduce laws, nonlinear relationships, and causal effects from extensive datasets with relatively low information density. Techniques like machine learning are employed to uncover relationships, dependencies, and predictions related to outcomes and behaviors.

In Triboinformatics, informatics techniques and tribology are integrated to gain insights into systems that do not adhere to established physical and chemical first principles. This Special Issue is focused on recent advancements in algorithm developments and their applications in the field of tribology. Specifically, it hones in on intelligent algorithms that have been employed to analyze and extract knowledge from diverse tribological data sources, including tabular data, time series, spectra, images, and videos. The emphasis lies in studies where intelligent algorithms have been utilized to predict tribological properties or design systems and materials with optimized tribological characteristics.

Experimental investigations are time-consuming and costly, especially for reciprocating seals in fluid power systems.

Gaining insight into tribological systems is crucial for optimizing efficiency and prolonging operational lifespans in technical systems. Experimental investigations are time-consuming and costly, especially for reciprocating seals in fluid power systems. Elastohydrodynamic lubrication (EHL) simulations offer an alternative but demand significant computational resources. Physics-informed neural networks (PINNs) provide a promising solution using physics-based approaches to solve partial differential equations. While PINNs have successfully modeled hydrodynamics with stationary cavitation, they have yet to address transient cavitation with dynamic geometry changes. This contribution applies a PINN framework to predict pressure build-up and transient cavitation in sealing contacts with dynamic geometry changes. The results demonstrate the potential of PINNs for modeling tribological systems and highlight their significance in enhancing computational efficiency. Full article

An enhanced YOLOv8 algorithm is proposed in the following paper to address challenging issues encountered in ferrographic image target detection, such as the identification of complex-shaped wear particles, overlapping and intersecting wear particles, and small and edge-wear particles. This aim is achieved by integrating the main body network with the improved Deformable Convolutional Network v3 to enhance feature extraction capabilities. Additionally, the Dysample method is employed to optimize the upsampling technique in the neck network, resulting in a clearer fused feature image and improved precision for detecting small and edge-wear particles. In the head network, parameter sharing simplifies the detection head while enhancing convergence speed and precision through improvements made to the loss function. The experimental results of the present study demonstrate that compared to the original algorithm, this enhanced approach achieves an average precision improvement of 5.6% without compromising the detection speed (111.6FPS), therefore providing valuable support for online monitoring device software foundations.
