Elastic Distortion

The untwist of rotating blades in turbomachines treated so far in the literatare simply as a pure elasticity problem is generalized and formulated rigorously as a problem of aeroelasticity by variational principles (VPs) and generalized VP (GVP). It takes into account not only the centrifugal force, but also the aeroelastic interaction between blades and the flow as well as the elastic distortion of the cross section shape of blades, assuming the material to be linearly elastic but nonisotropic. Thus, a new rigorous theoretical basis for the finite element analysis of blade untwist in turbomachine design is provided.

This thesis studies deeply the crack development characteristics, failure pattern, hysteresis curve and the displacement ductility of unbonded precast reinforced concrete frame, by analyzing one unbonded precast reinforced concrete frame under low reversed cyclic load test. We build a model using finite element analysis software to the test piece model analysis, the analysis result agree well with the experimental results. So we build finite element analysis models with different design parameters to analysis the impaction for seismic performance. Numerical analysis results can provide a scientific reference for the unbonded precast frame structure design.

In order to study the force capacity of the cross steel reinforced concrete special-shaped column in horizontal load, the finite element analysis software ABAQUS has been used. We adopt a horizontal direction displacement loading method to apply horizontal load, and its displacement is 20mm. We simulate the stress distribution of the six rates of steel bone and the six different cross section sizes of steel reinforced concrete special-shaped columns. According to the result, the load - displacement curve has been dropped, and we analyze the mechanical properties of cross steel reinforced concrete special-shaped column by the curve. The results show that the bearing capacity of cross steel reinforced concrete special-shaped column has improved with the increasing of rate of steel bone and the cross section size.

The paper makes an analysis of the reinforced concrete beams with exterior FRP Shell in Finite Element, and compares it with the test results. The results show that, by means of this model, mechanical properties of reinforced concrete beams with exterior FRP shell can be predicted better. However, the larger the load, the larger deviation between calculated values and test values. Hence, if more accurate calculation is required, issues of contact interface between the reinforced concrete beams and the FRP shell should be taken into consideration.

The Finite Element Analysis

Put the finite element analysis of line tower coupling modeling to the collapse of a 110 kV line straight-line tower, study the effect of strong wind on transmission tower and wire. The results show that under the action of strong wind, the material specification selected by the part of the rods on the type of tower is lower, cross section is smaller, the principal material of tower will be instable and flexional under the compression, resulting in tower collapsed.
