The article examines the aspects of predicting the durability of equipment components assembled using polymer reinforcing compounds. A method for calculating the key parameters of joints that have a primary impact on the durability of friction units is presented.
Modeling and simulation technologies play an important role in the operation, diagnosis of the current state and prediction of changes in various mechanical systems. The most effective approach for the study of nonlinear friction systems is the use of the method of physical and mathematical modeling, which is based on the construction of a mathematical model of a quasi-linear subsystem of a machine or mechanism and the creation of a physical model of a substantially nonlinear friction subsystem. Fundamentally new approaches have been developed to solve the problems of optimization, increasing the efficiency and competitiveness of non-linear technical systems using the example of the wheel-rail tribosystem. Proposed technology of metal cladding of locomotive wheel band and implementation of anisotropy of friction coupling provide significant increase of efficiency of “wheel-rail” tribosystem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
