Improve working environment It is very necessary to find an effective method to solve and control the noise of machine tool equipment. Noise reduction foam aluminum plate is a new functional structural material developed in recent years. Noise reduction foam aluminum plate has excellent characteristics of damping, sound absorption, sound insulation, heat dissipation and light weight .
Therefore, using Noise reduction foam aluminum plate as the inner liner of machine tool will be an effective way to reduce noise of machine tools.
Through various tests, the noise value of the spindle box with Noise reduction foam aluminum plate lining board is about 81dB Less than 85dB The highest noise frequency of the lathe is 1000Hz The noise value is reduced by 6 ∙ 14dB The noise of the machine tool is effectively reduced.
Conclusion of Noise reduction foam aluminum plate
(1) adding Noise reduction foam aluminum plate lining to the spindle box of machine tool can effectively reduce the noise of machine tools.
(2) the damping capacity of the foam aluminum / cast iron composite plate structure is studied. The contact between the Noise reduction foam aluminum plate and the cast iron box will also have a great influence on the damping of the structure. When the surface roughness, porosity and other factors cause the contact between the steel plate and the aluminum foam layer is not complete. There will be friction damping Further increase the structural damping It will further improve the anti vibration ability and sound insulation performance of the cover plate. Therefore, the Noise reduction foam aluminum plate will have great development prospects. This provides a theoretical basis for the application of Noise reduction foam aluminum plate of machine tools. It is of great theoretical significance to explore new ways to reduce the noise of machine tools and expand the application field of Noise reduction foam aluminum plate.
