ANALYTICAL CALCULATION AND EXPERIMENTAL RESEARCH ON THE BEARING CAPACITY OF FAN-SHAPED HYDROSTATIC THRUST BEARING SUPPLIED WITH CONSTANT OIL FLOW by WANG ShaoLi, XIONG WanLi, MENG ShuGuang, GUI Lin, XUE JingYu, FU MaLi

“…In the traditional design method of heavy duty hydrostatic rotary table,the influence of centrifugal force has not been considered in the calculation of bearing capacity of fan-shaped hydrostatic thrust bearing supplied with constant oil flow and the adopted simplified calculation method is lack of experimental verification.In this paper,a new analytical calculation method of bearing capacity of fan-shaped hydrostatic thrust bearing supplied with constant oil flow is presented in which the influence of centrifugal force is considered.The experimental system of heavy duty hydrostatic rotary table is designed and established,and corresponding experiment is carried out.The experimental results have a good fitness with analytical calculated ones,which has verified the validity of the proposed calculation method.The new method provides a theoretical basis for the design and calculation of the fan-shaped hydrostatic thrust bearing supplied with constant oil flow.…”

PREPARATION AND TENSILE PROPERTY OF 3D POROUS LATTICE STRUCTURE FOR SKIN TISSUE ENGINEERING SCAFFOLDS by FANG Chuang, JI XiaoGang, WANG Wei

“…Digital light process(DLP)forming method has the high forming speed and accuracy characteristics,and can be better used for the preparation of tiny size structures.Therefore,in this study,a new 3D porous lattice structure obtained by artificial topology⁃optimized square lattice as a single cell and spatial 3D equally spaced array of the single cell was designed.Then a flexible and elastic photosensitive resin by using DLP forming method for preparation experiments was carried out.The influence of DLP printing on the formation of the lattice structure and the forming effect were investigated.The tensile mechanical properties of all samples of complete structure without siltation were studied.The results show that the new porous structure prepared by DLP printing has clear internal pores and good connectivity in which the porosity reached more than 80%,and the elongation at break is also above 856%,among which the tensile toughness of lattice structure 3 is the largest and its comprehensive tensile properties are the best.The structure can be widely used in skin tissue engineering scaffolds,flexible electrodes,fragile product clamping fixtures,etc.…”

Reconstruction of sparse check matrix for LDPC at high bit error rate by Zhaojun WU, Limin ZHANG, Zhaogen ZHONG, Renxin LIU

“…In order to reconstruct the sparse check matrix of LDPC, a new algorithm which could directly reconstruct the LDPC was proposed.Firstly, according to the principle of the traditional reconstruction algorithm, the defects of the traditional algorithm and the reasons for the defects were analyzed in detail.Secondly, based on the characteristics of sparse matrix, some bit sequences in code words were randomly extracted for Gaussian elimination.At the same time, in order to reliably realize that the extracted bits sequence could contain parity check nodes, the multiple random variables were determined based on the probability of containing check nodes in one extraction.Finally, the statistical characteristics of LDPC under the suspected check vector was analyzed.Based on the minimum error decision rule, the sparse check vector was determined.The simulation results show that the rate of reconstruction of most LDPC in IEEE 802.11 protocol can reach more than 95% at BER of 0.001, and the noise robustness of the proposed method is better than that of the traditional algorithm.At the same time, the new algorithm not only does not need sparseness of parity check matrix, but also has the good performance for both diagonal and non-diagonal check matrix.…”
