The EHL calculatlon of helical gear with toothprofile modification along contact lines;

Tests have been made in room temperature and high temperature for seed alloy contact line(cross section 120mm~2)made from 19mm CuAl alloy bar by colddrawing.

With the curved surface of the roller as the research object, the paper works out its contact line and landmark by graphic method and analytic method respectively.

Effect of cold working on aging characteristics and mechanical properties of Cu-Cr-Zr-Y alloy contact wire;

Experimental research on continuous extrusion cladding forming of the copper-clad steel contact wire blank;

Compare of Ag-Cu contact wire technology and properties;

Study on contacting line of two intersecting pipes in welding assembly;

MATLAB-based analysis of contacting lines and numerical surface drawing of Hindley Worm;

The aim is to figure out,with the combination of the actual rolling,the shape of work-piece,the contact curve between rollers and work-piece and the interference of rollers,and the methods for inspection.

For spatial cam mechanism, it is different in pressure and pressure angle at each point with the contact curve between the cam and the roller.

The Research of Kinematic Model and Cut Remainder in Line-contact Rotating-milling Conical Surface;

The Experimental Research of Surface Roughness in Line-contact Milling Plane;

To analyze the machined quality of cylindrical surface with line-contact rotating-milling,the kinematic model of tool-teeth is built based on vector theory.

Simplification and application of calculation formula for linear contact minimum lubricant film thickness

The influence of temperature field and force is studied by simulation technique, the friction quantity is calculated simulated and the model of the numerical simulation about linear contact parts is brought, which can deliver a instruction to the numerical simulation about linear.
