Maximal Displacement

The influence of diameters and loads on the displacement of truss supporting system is evaluated based on the results of the finite element analysis on the steel-tube truss supporting system of silo. The vertical displacement increases with the increasing of the load. The displacement increases with the increasing of the diameter in the same loads. The maximal displacement appears in the intermediate position of the truss, and the displacements of symmetric nodes are similar under the symmetric loads. The member yields before 30m of truss supporting system reaches the allowable deflection.

The Finite Element Analysis

In the airport pavement design, the critical load position has the guiding significance for the airport pavement slab design. The finite element analysis model of rigid airport pavement is built, and 2-slab model and 9-slab model are analyzed. The corresponding load positions are obtained when the maximum stress and the maximum vertical displacement happen

MEMS are the manufacturing of a wide variety of items that are mechanical and electronic in nature. This paper describes a capacitive accelerometer technology using sense element structures. The sense element consists of a symmetrically flat plate of mass supported by four L shaped cantilevers, beams and frameworks. Capacitor plates located on the surface are used to detect the displacement. By using the finite element analysis method to build a model, analyzing the maximal displacement of mass, resonant frequency and stress of cantilever beam with different length, width and thickness.

In order to improve the anti-seismic performance of the NC tool rods in the cutting processing, it’s necessary to study the knife shaft material’s influence to its anti-seismic performance. Based on the finite element analysis of the different materials’ NC tool rods, the study obtains their distribution diagrams of the displacement distribution and the maximal displacement parameters by simulation of the actual processing. And the results show that the material of the NC tool rods has an important influence on their anti-seismic performance, thus it provides a basis for the material of the NC tool rod’s choice and using.

The influence of length of chord and depth of truss on displacement and bearing capacity of truss construction platform was evaluated based on the results of the finite element analysis on eight different diameters of the top steel-tube truss construction platform of silo. The bearing capacity increases with increasing of depth of truss. The bearing capacity increases with decreasing of length of chord. The maximal displacement increases with increasing of the diameter in the same joint loads, and the displacement curve of model fits better.

The design and practice of a deep excavation in shanghai was presented. The FEM based on Mohr coulomb Model was adopted to analyze the deformation of the excavation and its effect on adjacent buildings. This method gives good prediction of both the deformation of the soil retaining structures and the settlement of the soils behind the wall after comparing with measured datas. Meanwhile, the method is suitable to deformation analysis of sensitive environment circumstance.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.
