Seismic Response Analysis of Shaft Tower Based on The Interaction of Soil-Well Bore-Shaft Tower

To study the influence of soil-well bore-shaft tower interaction on the seismic response of the shaft tower. A numerical analysis model of rigid foundation (without considering the interaction of soil-well bore-shaft tower ) and II site considering soil-well bore-shaft tower interaction is established by the finite element analysis method. The mode period, tower layer displacement and inter-story displacement of shaft tower are analyzed. The results show that, compared with rigid foundation, considering the interaction of soil-well bore-shaft tower, the mode period of the system is prolonged, the tower layer displacement and inter-story displacement of the shaft tower is enlarged. In the engineering design of shaft tower, the influence of the soil-well bore-shaft tower interaction on the seismic response of the shaft tower cannot be ignored.

Numerical simulation and experimental validation of solar greenhouse dryer using finite element analysis for different roof shapes

The word greenhouse dryer is used for a building which is highly glazed with thermal conditioning for desired range and it is used for cultivating crops, plants, vegetables, etc. The actual working of a greenhouse is that the short-wave radiations falling on the greenhouse are absorbed by the outer glazing material thereby heating the interior area of greenhouse and providing ambient heat for plants, vegetables growth respectively. The heated space is retained within the enclosure of greenhouse. This phenomenon is called as greenhouse effect. The important role played during the greenhouse effect phenomenon are atmosphere, insulating roofs, walls, etc. The current study focuses on the numerical and experimental validation of Solar Greenhouse which is utilized for drying phenomenon. The numerical simulation is performed using Finite Element Analysis method. The various roof shapes have been incorporated to have emphasis on maximum solar gain to drying phenomenon.

Simplified Beam Element Model of Badminton Batting Process Based on Motion Differential Equation

Badminton is not only a traditional sport in China, but also an advantage sport in China. It has good entertainment, appreciation, and exercise, as well as a very broad mass base in China. Badminton racket as the key equipment of badminton, its production and design has a very critical impact on the development of the sport; the current existing research lacks the analysis of badminton batting moment. In order to more intuitively and clearly understand the force and displacement relationship of the racket net at the moment of badminton hitting, this study is based on the differential equation of motion, combined with the finite element analysis method to build a simplified beam element model. In order to verify the reliability of the model, the displacement of the beam element and the rod element of the badminton racket under the same load is constructed. Through the research results, it can be seen that the beam element model is more reliable for the numerical calculation of badminton batting moment. The in-depth analysis of badminton batting process has a certain reference significance for the production and design of badminton racket.

Finite Element Analysis of Three-ring Reducer

The tricycle reducer is widely used in many fields such as mining, petroleum and building materials because of its characteristics of large transmission ratio, compact structure and wide application, as well as its excellent carrying capacity and low cost. In order to understand the force of three-ring reducer, the finite element analysis method should be adopted. This paper, starting with the structure and working principle, carries out the multi-tooth meshing effect and the whole machine statics analysis, aiming to provide a reference for the optimization and perfection of the products.

Finite Element Analysis Method of Slope Stability based on Fuzzy Statistics

In order to reduce the risk of slope stability evaluation due to the fuzziness of calculation parameters, a finite element analysis method of slope stability based on fuzzy statistics is proposed. Based on the principle of quasi-static method and with the help of the finite element software COMSOL multiphysics, this paper studies the stability of the gravel soil accumulation rock slope under the action of different seismic acceleration. By analyzing the displacement, plastic zone and safety factor of the rock soil slope, the stability of the rock soil slope is analyzed. The research results show that the fuzziness of mechanical parameters of rock and soil slope will lead to the fuzziness of position displacement and stress analysis results of rock and soil slope, and the analysis of rock and soil slope with the method of fuzzy finite element analysis can strengthen the comprehensive understanding of position displacement, stress and safety of rock and soil slope by engineers and technicians, and reduce the stability of rock and soil slope due to the fuzziness of calculation parameters to a certain extent Evaluate the risk qualitatively.
