With the development of computer hardware and software technology, virtual reality technology of computer has been widely used in various fields. Virtual teaching process is one of the main applications of virtual reality computer technology. Tennis is one of the most common sports. Tennis process mainly includes the process of catching a ball, serving a ball and hitting a ball. Virtual process of tennis system must establish an accurate numerical simulation model to calculate the mechanical impedance during the arm movement of human. According to this, it builds a model of the mechanical impedance of human arm in tennis virtual system using three-dimensional simulation software in this paper and gets the curve of mechanical impedance through the simulation. Finally, the article compares calculation results with the theoretical results and concludes that the theoretical results and simulation results are basically consistent which provide a theoretical reference for the design of the development of virtual system for the human.

In recent years, soft modular robots have become popular among researchers with the development of soft robotics. However, the absence of a visual 3D simulation platform for soft modular robots hold back the development of the field. The three-dimensional simulation platform plays an important role in the field of multi-body robots. It can shorten the design cycle, reduce costs, and verify the effectiveness of the optimization algorithm expediently. Equally importantly, evolutionary computation is a very effective method for designing the controller of multi-body robots and soft robots with hyper redundancy and large parametric design space. In this paper, a tradeoff between the structural complexity of the soft modular robot and computational power of the simulation software is made. A reconfigurable soft modular robot is designed, and the open-source simulation software VOXCAD is re-developed to simulate the actual soft robot. The evolutionary algorithm is also applied to search for the most efficient motion pattern for an established configuration in VOXCAD, and experiments are conducted to validate the results.

Dimensional Simulation

This paper studies the cylindrical acoustic emission signal generation, propagation and attenuation. Acoustic emission signal is a form of elastic waves and mechanical waves also. The large finite element physics simulation software COMSOL is used to simulate the propagation of acoustic emission signals coursed by the oil tank bottom corrosion. Simulation is divided into two parts，they are separately two-dimensional simulation and three-dimensional simulation. The bottom part of oil tank is two-dimensional simulation and the entire tank is three-dimensional simulation. Two-dimensional simulation is achieved in different situations. Strength of point source are the same in different positions, and the same point source position has different intensity. Acoustic emission wave propagation has a greater relationship with the media of dissemination, the point source position and the different interfaces.

The Mathematical Model

Shanghai Shikumen house is a typical one of Chinese traditional residential architecture, which has a "two patios & one corridor" pattern adapting to the climate of Shanghai. In existing researches, most study of the thermal performance dwelling with courtyard is still qualitative. This research constructed the quantitative simulation of the " two patios & one corridor" pattern in Shanghai Shikumen house based on the mathematical model by the technical simulation software, and compared the above mode with the general courtyard house to test the advances of it. First of all, the research conduct a three-dimensional simulation analysis on the "two patios & one corridor" pattern and the general "Two patios" pattern. Then we compared the results of the wind environment of the two modes and found the "two patios & one corridor" mode has advances on ventilation. Secondly, we did thermal environment simulations of the rooms in the above two modes, and compared the analysis results of two modes. We found that the "two patios & one corridor" pattern did better in the room thermal. Finally, we hope this research can provide certain reference for the design of the sustainable residential architecture.
