This paper applies parametric design in meridian unfolding wheel s building,and puts forward a mix modeling method by combining law curve with free form modeling in UG NX 2.

Analysis of the effects of residual stress in reinforcing cords on the finite element simulation of radial tire;

Finite element analysis for radial tire contact problems;

Influence of carbon black on heat conductivity of radial tire tread;

Application of domestically produced white carbon to compound for the radial tyre;

Using the Non-linear analysis technology of ANSYS software,the three-dimension finite element model of radial tyre of R15 type of 60 series is built with three-dimension volume element,layer element and contacting element.

SR13 and P215/75R15 radial tyres were produced in a pilot run with 1000D/3 polyester cord made in Shandong Anqiu Polyester Cord and Canvas Factory.

Feature of meridian tyre, and the process folw of the type of tyre mold are introduced.

Domestic meridian tyre and steel tyre cord industry develops rapidly in recent years.
