Finite-Element Analysis on Seismic Behavior of Hexagonal-Hole Variable Cross-Section Honeycomb Beam Portal Rigid Frame

A new steel special-shaped lattice column (SSLC) was proposed, which can be used in prefabricated steel structure residence. The finite element models of four SSLC with different cross-section (L-shaped, T1-shaped, T2-shaped and X-shaped) were established under cyclic loading by using ABAQUS, in which the strength, lateral resist capacity and hysteretic behavior were analyzed. The results indicate that SSLC has adequate strength, stiffness and safety redundancy. Among the four SSLC, the SSLC with X-shaped has the best structural performance and seismic behavior.

Screw Rotor

Bulge forming is a novel process aimed at common products including T-branches, cross branches and angle branches. But bulging forming has not applied for two-head abnormity-shaped hollow screw rotor reported in literature. Simulation of the bulging forming of two-head abnormity-shaped hollow screw rotor has not been reported. This paper presents a simulation of the bulge forming process of two-head abnormity-shaped hollow screw rotor using a variable cross-section solid bulging mold. Some conditions including the effect of friction, boundary conditions, contact conditions and the space motion, etc are presented. The mathematical model of three-dimensional finite element analysis has been established. The distribution of generalized plastic strain and general metal flow mode in cross section of two abnormity-shaped hollow screw rotor has been analyzed. It is an effective method for the analysis of other defects and the optimization of process parameters further.

Rigid Frame Bridge

The composite steel–concrete rigid frame bridge is composed of steel or composite girders connecting rigidly to RC piers, and has advantages of lower maintenance costs, faster construction, and higher resistance and ductility during an earthquake. In this paper, a new type of steel–concrete composite rigid connection is developed and studied by finite element analysis. The comparison with other types of connections shows that this new type of connection has a good structural performance from the confining of concrete by steel and preventing the buckling of steel by concrete.

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.

High Output

Abstract Thermomechanical in-plane microactuators (TIMs) have been designed, modeled, fabricated, and tested. TIMs offer an alternative to arrays of smaller thermal actuators to obtain high output forces. The design is easily modified to obtain the desired output force or deflection for specific applications. The operational principle is based on the symmetrical thermal expansion of variable cross sections of the surface micromachined microdevice. Sixteen configurations of TIMs were fabricated of polysilicon. Finite element analysis models were used to predict the deflection and output force for the actuators. Experimental results were also recorded for all sixteen configurations, including deflections and output forces up to 20 micron and 35 dyne.
