Driving properties of plane wire-driven robotWANG Ke-yi(王克义)1,2, ZHANG Li-xun(张立勋)1, MENG Hao(孟浩)2(1. College of Mechanical and Electrical Engineering, Harbin Engineering University, Harbin 150001, China; 2. College of Automation, Harbin Engineering University, Harbin 150001, China)Abstract:a three-DOF (degree of freedom) planar robot completely restrained and positioned parallel pulled by four......
between the growth of Cr3C2 and the diamond crystal plane. After the filler is melted, two layers of carbide are formed on the diamond surface, the inner layer is order Cr3C2, and the outer layer is disorder Cr7C3. Key words: vacuum brazing; diamond; carbide; orientation relationship; crystal plane  ......
on DFT, and the equilibrium and growth morphology of systems were analyzed by using crystal growth habit program morphology. The experimental results show that the silicon dioxide influences... obviously when SiO32? is located on the surface, and the stability of the system with more oxygen atom is lower. The calculation results of equilibrium morphology and growth habit show that the volume......
University, Changsha 410083, China)Abstract:The original descriptive model of shear stress and shear displacement only reflects the stress deformation characteristics of plastic structural plane. The index model was revised and piecewise index model was built to describe the stress deformation characteristics of plastic structural plane and brittle structural plane. The relation of stress......
evolutions of texture and grain boundary plane distributions in a ferritic stainless steelFANG Xiao-ying(方晓英)1, WANG Wei-guo(王卫国)1, GUO Hong(郭红)1, QIN Cong-xiang(秦聪祥)1, ZHOU Bang-xin(周邦新)2(1... boundary plane distributions in a cold-rolled and annealed ferritic stainless steel were investigated by means of EBSD techniques. The results show that, following cold rolling with the thickness......
