| Abstract: | The ram is the most important part of the NC Boring and Milling Machine.The deformation of the ram influence the accuracy of the machining.Solid model of the ram has been built by software.Its static analysis,displacement and stress have been proposed based on the finite element method.One to four frequencies and dynamic characteristics of ram had been performed by modal analysis.The result will guide the design and optimization of the ram. |
