A multi-scale dynamics analysis method for the anisotropic single-crystal blade with fretting wear
This paper aims to investigate the wear evolution of contact interfaces and their impact on the nonlinear dynamics of anisotropic single-crystal blades. A modeling method for anisotropic blades is proposed, accompanied by a numerical simulation method that examines contact, friction, and wear behavior. Furthermore, a multi-scale dynamics solver is developed to analyze the behavior of anisotropic blades experiencing fretting wear. This method is applied to a shrouded single-crystal blade system, effectively predicting the wear behavior and its influence on the nonlinear response. Ultimately, the contributions of distinct anisotropic crystal orientations in single-crystal turbine blades to wear behavior and nonlinear dynamics are elucidated. It is determined that the nonlinear response, accounting for wear, is predominantly influenced by the angle β.
期刊介绍:
Applied Mathematical Modelling focuses on research related to the mathematical modelling of engineering and environmental processes, manufacturing, and industrial systems. A significant emerging area of research activity involves multiphysics processes, and contributions in this area are particularly encouraged.
This influential publication covers a wide spectrum of subjects including heat transfer, fluid mechanics, CFD, and transport phenomena; solid mechanics and mechanics of metals; electromagnets and MHD; reliability modelling and system optimization; finite volume, finite element, and boundary element procedures; modelling of inventory, industrial, manufacturing and logistics systems for viable decision making; civil engineering systems and structures; mineral and energy resources; relevant software engineering issues associated with CAD and CAE; and materials and metallurgical engineering.
Applied Mathematical Modelling is primarily interested in papers developing increased insights into real-world problems through novel mathematical modelling, novel applications or a combination of these. Papers employing existing numerical techniques must demonstrate sufficient novelty in the solution of practical problems. Papers on fuzzy logic in decision-making or purely financial mathematics are normally not considered. Research on fractional differential equations, bifurcation, and numerical methods needs to include practical examples. Population dynamics must solve realistic scenarios. Papers in the area of logistics and business modelling should demonstrate meaningful managerial insight. Submissions with no real-world application will not be considered.
