Механика машин, механизмов и материалов, 2019 The ball joints of vehicles are referred to the steering and suspension critical units. Strength calculation of the ball pin under static loading is usually performed in the practice of designing these units. In the article, the ball joint is considered as a tribo-fatigue system in which the zones that are dangerous in terms of bending stresses and ...

Assessment of the risk of contact fatigue damage in wheels and rails using the Dang Van criterion
Вестник Научно-исследовательского института железнодорожного транспорта, 2023 Introduction. Dynamic loads cause high contact stresses in the materials of wheels and rails, which leads to their wear and accumulation of contact fatigue damage. A number of approaches were proposed for calculations of contact fatigue and prediction of
