Calculation of the design life of solid-rolled wheels of railway rolling stock according to the criterion of reliability

Objective: Development of a methodology for determining the design life of solid-rolled wheels of railway rolling stock, based on the requirements of the current regulatory documentation. Methods: Methods of the theories of probability, reliability, elasticity and numerical solution of partial differential equations (finite element method) are applied. Results: A methodology for calculating the design life using the criteria of TR CU 001/2011, TR CU 002/2011 and GOST 33783–2016. Practical importance: The developed method will make it possible to exclude the presence of wheels with a significant service life on the railway infrastructure which do not provide the required level of reliability, which, in turn, can lead to sudden destruction of wheels under the cars.
