【 摘 要 】

The article presents a method of numerical integration of the movement equation of a dry friction oscillator. The results are compared with those obtained by an analytical method. The oscillator response is calculated at a harmonic excitation as well as the influence of high frequency vibrations. The application is interesting for studying the vibrations of freight wagons.
