Заглавие: Самовъзбуждащи фрикционни трептения на железопътна релса
Ключови думи: фрикционни трептения, системи с разпределени параметри, МКЕ

Абстракт: В работата са изследвани самовъзбуждащи се фрикционни трептения на железопътна релса при движение на подвижен железопътен състав при вписване в крива. Обектът на изследването е моделиран като система с разпределени параметри. Трептенията на релсата се възбуждат от нелинейната сила на триене, зависеща от релативната скорост на плъзгане между колелото и релсата. Задачата е решена в Matlab, в среда Simulink.

Title: Friction induced vibrations of a rail
Keywords: friction vibrations, continuous systems, FEM

Abstract: A model of rail, considered as multiple supported beam, subjected on friction induced vibration is studied in this work using FEM. The model is presented as continuous system and the mass and elastic properties of a real object are taken into account. The friction forces are nonlinear functions of the relative velocity during slipping. The problem is solved using Matlab Simulink.
