SIMULATION AND EXPERIMENTAL STUDY ON THE STATIC STIFFNESS OF HIGH SPEED MOTORIZED SPINDLE by CUI FangYuan, LI Yan, YU JiaYi, TANG AoFei, LI PengYang, HAN LiLi

“…The static stiffness of the spindle is an important index to evaluate the static characteristics of the motorized spindle,which is essential to ensure the machining accuracy of precision CNC machine tools.Based on the calculation formulas of cutting force under typical conditions and those of radial stiffness of angular contact ball bearing,the axial deformation in front of the spindle,as well as the static stiffness in the specified condition,were obtained through the 3D finite element model of rotor-bearing system.The static stiffness test was performed on the experimental platform.By comparing the simulation results and the experimental results,the validity of the finite element model was indirectly verified.Based on the reliable finite element model,the variations of the static stiffness of the spindle with the preloads of the front and rear bearing groups were gained.…”

Broadband Frost Adaptive Array Antenna with a Farrow Delay Filter by Tao Dong, Qiushi Wang, Yunxiao Zhao, Lixia Ji, Hao Zeng

“…In this paper, we propose a Farrow structure instead of a direct form FIR structure to implement the time delay filter since it can satisfy the demand for real-time update and is very suited for the FPGA platform. Furthermore, a new off-line algorithm to calculate the Farrow filter coefficient is presented if the filter coefficient is symmetric. …”

Similar text positioning method based on slope-density cluster by Du ZOU, Wen-jun TANG, Wei-jiang LONG, Ling ZHANG

“…Similar text positioning is an important part of plagiarism detection.The existing positioning method directly merges text or fingerprint to obtain similar text.Due to the disturb information in the similar text,the positioning accuracy is poor.The semantic features of the match fingerprints were analyzed,and a cluster method based on slope density for similar text positioning was proposed,which converts the text merge problem into dense sample points clustering problem,and improves the efficiency and accuracy of the positioning.Through the experiment on the PAN public corpus,the result shows it performs better than the PAN10 top three.This method has been used in the South China University of Technology 's feature professional teaching platform to detect the plagiarism of homework.…”
