Time-Domain Regenerative Chatter Analysis of Non-linear Stiffness System
Popis výsledku v původním jazyce
The phenomenon of self-excited vibration during machining still plays a key role in the productivity of a machine tool. The phenomenon was deeply analyzed by many works, but in the new prototype testing, unexpected behavior occurs. The hypothesis is that is caused by nonlinearity. This paper presents the approach of the time domain simulation of grooving cutting process for nonlinear analysis. The simulations compare linear stiffness model with two nonlinear, all these models were built by fitting measured static stiffness data by a regression model and also were built to have a similar response on modal hammer impulse, mainly the similar negative real part of the system response. The main idea for these simulations is to evaluate the effect of nonlinearity on system stability and primarily enables the description of vibration magnitude in the unstable region. The results showed that that nonlinear model has an influence on stability lobes and mainly on the magnitude of vibration in the unstable region which is significantly changed.
