پیاده سازی تکنولوژی افزودنی به طراحی و ساخت ارتعاشات با فیلتراسیون مورد نیاز

The 3D printing technology of selective laser melting is described for the synthesis of a light weight vibro-isolating system. The original design of this system manufactured by casting material is based on a grid-like steel structure that may significantly decrease amplitudes of vibration at several hundred Hz. It is shown that the similar structure which is manufactured by 3D printing has smaller mass while the strength parameters are the same. Mechanical properties of the synthesized material have been studied in comparison with the material cast to ensure the mechanical properties of the printing vibroisolators. Two types of metal powders of stainless steels 07H18N12M2 and 316L are considered. It is obtained that the synthesized material has the tensile strength and yield strength values of 15% and 63% higher than the material cast. The results may be useful for development of space instruments isolation from external vibrations in the certain frequency range.
