Abstract
The article considers the design, as well as a regression analysis of the spread of values of horizontal elastic-dissipative connections of the 1st and 2nd stages of spring suspension of high-speed and high-speed electric trains. In order to assess the influence of the longitudinal and transverse stiffness of the wheelset connections with the bogie frame, as well as the dissipation of the longitudinal hydraulic vibration damper of the 2nd stage of suspension on the stability of the crew movement, a numerical study was carried out using a mathematical model of a trailer car of the Sapsan electric train in the Universal Mechanism software package
