Light steel temporary building is commonly used in the construction site, with advantages on simple structure, repeat used and small deadweight. There are still not enough researches and relevant standards to conduct the design and construction of the buildings. In order to precede to theoretical study on integral structure of light steel temporary buildings a method which used to set up finite element analysis model about integral structure of light steel temporary buildings was proposed in this paper. The method is based on finite element analysis software, Ansys. Using this method a monolayer integral structure, a two-story integral structure and a trilaminar integral structure model were set up. Lateral displacement under design load of the integral structure was solved out by these finite element models.

Mobile steel building is a prefabricated building built in a factory, with advantages on moving conveniently, simple structure and scalability. There are still not enough relevant standards and requirements to conduct the design and construction of this kind of buildings. In order to precede to theoretical study on integral structures of mobile steel buildings a method which used to set up finite element analysis model about this kind of structure was proposed. This method is based on finite element analysis software, ANSYS. Using this method a two-story structure model with one box unit in each story was analyzed. Lateral deformations under design load of the integral structure were solved out by these finite element models and were compared with the former experimental results, and the results were discussed.

Directivity Characteristics

We propose a model to give us a method to investigate the characteristic three-dimensional directivity in an arbitrarily configured flexible electret-based loudspeaker. In recent years, novel electret loudspeakers have attracted much interest due to their being lightweight, paper thin, and possessing excellent mid- to high-frequency responses. Increasing or decreasing the directivity of an electret loudspeaker makes it excellent for adoption to many applications, especially for directing sound to a particular area or specific audio location. Herein, we detail a novel electret loudspeaker that possesses various directivities and is based on various structures of spacers instead of having to use multichannel amplifiers and a complicated digital control system. In order to study the directivity of an electret loudspeaker based on an array structure which can be adopted for various applications, the horizontal and vertical polar directivity characteristics as a function of frequency were simulated by a finite-element analysis model. To validate the finite-element analysis model, the beam pattern of the electret loudspeaker was measured in an anechoic room. Both the simulated and experimental results are detailed in this article to validate the various assertions related to the directivity of electret cell-based smart speakers.

Friction Lining

Brake friction lining material is the critical element of a braking system, since it provides friction resistance to the rotating drum for controlling automobiles. The present study involves wear analysis of newly developed eco-friendly non-asbestos friction lining material for automotive drum brake applications using experimental study, finite-element analysis, and microstructural investigations. Theoretical interpretation of braking force at different automobile speeds was derived using fundamentals. Specimen drum brake liner with eco-friendly material compositions was produced using an industrial hot compression molding process at one of the manufacturer. The surface wear of the liner was measured using an effective and accurate method. Furthermore, a finite-element analysis model was developed considering actual operating conditions and various components of the drum brake system. The model was elaborated for various result outcomes, including Von-Mises stresses and total deformation of components of the drum brake, and further used to estimate the surface wear of the friction lining material in terms of transverse directional deformation. Finally, microstructural analysis of the friction lining material was carried out using scanning electron microscopy and energy dispersive spectroscopy. From the results, it is seen that the developed friction lining material is wear resistant. The finite-element analysis model can be effectively utilized to study the tribological characteristics of friction lining materials.

This paper studies the force and deformation of the connecting channel in Ningbo rail transit construction, which firstly used the mechanical shield method. Steel-concrete composite structural segments are used in the T-joint of connecting channel. The cutting part of the segments are replaced by the concrete and fiberglass instead of reinforced concrete. Basing on a variety of three-dimensional design software and ABAQUS finite element analysis software, a refined finite element analysis model of the special segments is established. By considering the influence of curved joint bolts, the force analysis of the special segments under the structural state before and after construction is performed. According to the analysis and comparison of the deformation of the segments with and without the bolts, it is concluded that the steel-concrete segments can withstand the pressure of the soil before and after the construction. Suggestions for the safety of the design and construction of the segments are put forward.

The paper established U75V 100-meter rail 3-D transient non-liner finite element analysis model about U75V 100-meter rail by using the large-scale non-liner finite element analysis software ABAQUS. By analyzing the different positions in the section of the temperature variation, the changes of bending degree and the residual stress variation after the bending deformation have changed. Based on the 100-meter straight rail in natural cooling under the cooling process, simulation results showed that in the cooling process, deflection change with time mainly divided into four stages; In consideration of the friction effect, the flat rail cold curve for its deformation among roughly flat, the curve about either ends, the scope for bending is 18 meters, the maximal displacement is 1.88 meters while the flat rail occured end colding.
