Polishing is a precision machining method to improve the material surface quality. This paper presents a new polishing method based on Position-velocity-time (PVT) interpolation in computer-controlled optical surface (CCOS). In order to verify the machining performance of the proposed technology, a series of analytical and experimental investigations were conducted. From the experimental results,...
On the condition of different dam heights and different shapes of river valley, 3-D dynamical responses of concrete-faced rockfill dams subjected to different seismic intensity input are analyzed based on equivalent-linear model in this paper. The results show that, the distribution of the acceleration along the dam heights at the edge points on the central section is S-shaped; the acceleration increases...
