A digitalization method of programming tire profile was established in CAD for tire structure design to significantly increase the flexibility in profile design of tire.

In this paper, a brief introduction is made to the design principle and standard of the high slope, the profile design of the high slope, drainage system against seepage, reinforcing and supporting measures and controlling measures during construction of the project.

TECO is a practical theory for radial tire structure which is based on the safety design calculation. the optimization of important parameters and the optimization of profile design.

The theory and implementation issues of the roll pass and profile design system are discussed. The system is developed with Visual Basic 5.0 on AutoCAD R14 platform. By means of feature-based parametric design and group technology, the roll pass design and drawing system has been worked out and put into daily use.

The equilibrium contour of radial tire is different from the mould contour. The success of the equilibrium contour design depends on the mould design,which should begin after the calculation of the restrained pneumatic equilibrium contour.

The ways of part balance contour design and optimization in parameters of different parts have been adopted to balance performances of 60 series tires in the developing work.

Tire designing gradually realizes automatic design and intelligent design with the development of high capable computer, computational technologies and software.

The excavation of intake for the underground powerhouse of Longtan hydropower station formed a slope as high as 435 m with the slope area of 270,000 m 2. The design must provide the reverse stratified rock high slope, which has complicated outline, with sufficient stability to ensure the safety operation of the dam section at intake.

Solutions for problems of profile design near a rigid wall or free surface are found as particular cases of the more general inverse problem of flow over an airfoil near an interface.

A cascade profile design method was proposed using the aerodynamic load and blade thickness distribution as the design constraints, which were correspondent to the demands from the aerodynamic characteristics and the blade strength.

Fully stressed thickness profile design at discontinuities of axisymmetric shells

However, by using the GA, the calculation time was reduced to about 1/389 that of the coventional method, showing that the method which uses the GA through the profile design is very useful.

It may be that profile design effects appear in our survey.

In fact, the actual and theoretical outlines of a cam contour are a group of equal-distance curved lines, and there is a normal line corresponding to the associated points.From this, we can directly find out the equation of curved lines of the actual cam contour by an analytic geometry.This method can simplify the equation and calculation of the actual contour.The procedure programmed by using the method are both reliable and universal and may be applied to designing the outline of a concentrte or eccentric...

To refit a crank-shaft press into P/M automatic press is a common way for some small-scale factories.One of the refitting constructions illustrated in this paper is cam operated coining device, which has been successfully used in a number of P/M factories. However, how to draw the outline of coining cam is an important key to the device designing. By studying the coinig process of the axle bushes and analysing the movement law of the follower, we can get the function fomular of working curve of the cam. Then,...

The cam is extensively applied to automated machine and equipment which process food and agricultural products. There are the graphic method and the analytical method in the design of the cam profile. We ofter apply the graphic method, however the error of the graphic method is bigger. The precision of the analytical method is very high, and it may apply Computer Aided Design. The cam profile design method which applies the computer is called C A D of the cam profile for short.

The cam is extensively applied to automated machine and equipment which process food and agricultural products. There are the graphic method and the analytical method in the design of the cam profile. We ofter apply the graphic method, however the error of the graphic method is bigger. The precision of the analytical method is very high, and it may apply Computer Aided Design. The cam profile design method which applies the computer is called C A D of the cam profile for short. The cams which are extensively applied in automated machine and equipment are rectilinear translating roller follower disk cam and oscillating roller follower disk cam. The paper discusses their concerning question of C A D of the cam profile and puts a scheme of compileing programme.
