Influence of the Cut Axial Depth on Surface Roughness at High-Speed Milling of Thin-Walled Workpieces

Наука и техника, 2021
The paper presents the results of research on the dynamics of end milling of thin-walled work-pieces having complex geometric shapes. Since the milling process with shallow depths of cut is characterized by high intermittent cutting, the proportion of ...

Analysis of the associated stress distributions to the nonlinear forced vibrations of functionally graded multi-cracked beams

Diagnostyka, 2021
Geometrically non-linear vibrations of functionally graded Euler-Bernoulli beams with multi-cracks, subjected to a harmonic distributed force, are examined in this paper using a theoretical model based on Hamilton's principle and spectral analysis.

Vibration of rigid bodies in the visco-elastic Hook-Maxwell model

Vietnam Journal of Mechanics, 1979
In this paper the self-excited and forced vibrations of rigid bodies fastened to visco-elastic beam are considered. Two parameters solutions of motion equations of third order are found in the asymptotic series and their stability is investigated.

FORCED VIBRATION ANALYSIS OF A MULTIDEGREE IMPACT VIBRATOR

Journal of Sound and Vibration, 1998
The dynamics of a multidegree impact vibrator subject to harmonic loading is investigated. The system is represented by a lumped mass model which hits and rebounds from a rigid wall during vibration. The periodic solution to the equations of motion with $N$ forcing cycles and $P$ impacts is formulated.
