Description
Technical field
The present invention relates to the application of particle damping in large size machine tool, particularly relate to a kind of supporting frame based on particle damping.
Background technique
Along with high-end precision assembly is towards high-power, high-speed, highi degree of accuracy, the developing rapidly of high flexibility direction, except requiring that equipment is lightweight, cost is low and have except good technology capability, when also requiring work, stationarity is high, noise is low.At present, domestic and international precision machine tool manufactory, for improving precision and reliability, usually adopts and strengthens structure wall thickness, increases the measures such as gusset, the technology difficulty of large-scale precision lathe and manufacture cost are significantly increased.
Particle damped vibration attenuation noise reduction technology is a passive vibration control new technology, for theoretical foundation with damping energy dissipation mechanism, by the nonlinearity dynamic system constituting a coupling between grain body and damper, close, friction between particle and between particle and damper and non clastic collision, promptly by oscillating body kinetic energy dissipation, have the advantages such as the rugged environment such as effectiveness in vibration suppression is obvious, high temperature resistant, vibration damping frequency domain are wide, little, a large amount of saving metallic material of associated mass that produces.
Therefore, how particle damping is better applied to and above-mentioned one of following research and development problem is become to precision machine tool.
Summary of the invention
In view of this, we provide a kind of supporting frame based on particle damping, without the need to large-scale precision lathe is returned factory, by means of only external support structure, the effect of vibration and noise reducing can be realized.
