Method for calculating the durability of a car wheelset
https://doi.org/10.46973/0201-727X_2024_3_109
Abstract
The wheelset is the main part of the car, its strength and durability are calculated using traditional methods. However, the issues of ensuring the durability of a wheelset during a given service life have been little studied in the theory of cars. In order to ensure the safe and efficient operation of wheel pairs of cars on the railway network, various requirements are imposed on them, which must first be confirmed by assessing strength and endurance indicators.
A method for calculating the probability of durability of a wheelset before reaching its limit state is proposed. The durability of the wheelset according to the fatigue endurance coefficient is determined based on the quantile, depending on the change in the stress difference. The study is made taking into account the main parameters of the mechanical properties of the wheelset (strength, geometric dimensions of the wheel pair, surface quality). The proposed method for calculating the durability of a wheelset can be applied as a progressive method to ensure the reliability of parts and units of cars, as well as other machines and mechanisms, which will increase the durability of the wheelset, as well as reduce the cost of maintenance and repair of wagons.
