High-speed milling of thin-walled part is a widely used application for aerospace industry. The low rigidity components, large quantities of material removed in machining progress, are in the risk of the instability of the progress. In this paper, the thin-walled parts have the similar characteristics with the tools. Therefore, the dynamic model and the stability critical condition determined by the...
This paper investigates the influence of soil-structure interaction (SSI) on seismic responses of long-span space truss roof. First, a three-dimensional (3D) integral finite element (FE) model of a typical regular pyramids space truss structure consisting of space truss roof and support columns is developed. By applying FE method for near field soil and infinite element (IE) method for far field unbounded...
