On the basis of it, the detailed calculation processes are given about the geometric nonlinearity cellular element method and contact nonlinearity cellular element method.

Affected by trolley under load, the pressure transferred from rail to box girder is of contact nonlinearity problem.

The finite element structure analysis for sulfurous acid purpose tank car-body is studied through the methods of contact nonlinear and couple degrees of freedom by using the finite element software ANSYS.

Based on contact nonlinear FEM,it analyzes the intensity and rigidity of motor stator iron-core shiplap pressuring frame by ANSYS,which provides a good method for designing and calculating the motor structure.

The analysis of the ultimate bearing capacity of joint in the concrete filled rectangular steel tube is presented in this paper by the finite element method with degenerate shell element and 3-D solid element, which takes into consideration the material nonlinear and the contact nonlinear which simulates the work between the steel tube and the concrete.

Structural analysis of wind turbine main shaft using nonlinear contact method

The method is based on the nonlinear contact analysis technique and optimum design technique of Ansys9.

Taking ANSYS Workbench as a tool,this paper simulates well the bearing-conjunction problem by means of building nonlinear contact between ball and rolling channel of bearing.
