Abstract In order to solve the problems of long development time, poor expansibility and small application scope in the digital design of secondary system of intelligent substation at present, this paper puts forward the 3D assembly techniques based on the expanded model by analyzing the integration of secondary model files of intelligent substation. In the design process of this method, the relationship between primary equipment and secondary equipment, the mapping between logical circuit and real circuit are fully considered. By using standard family library techniques, file analysis techniques and automatic mapping techniques, the coupling between physical model and logical relationship is realized. Taking the actual 220kV intelligent substation as the pilot, the three-dimensional model in secondary system simulation analysis, online monitoring and the application of fault diagnosis shows that the techniques can effectively improve the efficiency of three-dimensional design and maintenance of secondary system.

Based the CAE technology, the paper introduced the application of Moldflow Insight in injection mold design of mobile phone cover. First, we must preprocess the finite element model, including importing three-dimensional model, meshing, and process setting. And then, we can use preliminary simulation analysis to determine the number and location of the gate. Finally to filling, cooling, packing and warpage analysis for part which can help us to find the causes from warpage generated. By optimizing the molding process parameters, adjusting the dwell pressure and the dwell time we can get less warpage, which can meet the precision demand of parts, consequently, the result can provide gist for the mold designers to design and for the injection molding technologist to process parameter adjustment.

This article takes an efficient feeding head as the research object to study its work mechanism and perform dynamics analysis of the materials in the feeding head. In addition, this article obtains the physical prototype of a three-dimensional model and the feeding surface equation through the surface data of the feeding head and investigates different unfold lines of the feeding surface. In addition, this article recommends a curve equation of the feeding head under different friction coefficients through EDEM + FLUENT simulation analysis and conducts a research on transport and feeding quantity to deduce the equation for the transport quantity of the feeding head. Finally, the verity of the preceding curve equation and transport quantity is confirmed, which has important guiding significance for the feeding head design.

The speed increasing gearbox is the key part of the wind turbine and its role is to transmit power which is generated by wind turbines to the generator through the gear system. The single-stage planetary gears train system is commonly used in the semi-direct drive wind turbines. In this paper Pro/E is used to establish the three-dimensional model of the speed increasing planetary gear system of the semi-direct drive wind turbine. Motion pairs, drive and load of the model are added by ADAMS. Angular velocity change rule of the parts is obtained. The change rules of the mesh force of the planetary gears, ring and sun gear can be obtained through the dynamic simulation and analysis using the contact algorithm. These are useful to study the vibration and noise of the system.

Blade is one of the main parts of aircraft engine. Its dynamic characteristics will produce important influence on the work efficiency and the operation reliability of the turbine engine. The paper used the theory of finite element to do modal simulation analysis on the dynamic characteristic of blade flutter, aiming at the phenomenon of serious blade vibration in the process of turbine engine running. Firstly, the paper generated a three-dimensional model by using the software UG. Then the three-dimensional model was leaded into the finite element analysis software ANSYS. Simulation analysis of the model was carried out by using the Workbench module of ANSYS software. Finally, we got the former six order natural frequencies and vibration modes of the blade. In addition, we got the blade's vibration characteristics. The results of the simulation could provide numerical basis for the blades optimization design and vibration safety inspection.

: In this paper, I designed a differential planetary gear for flip climbing transmission system which was applied to the star-climbing wheelchair. According to space limitation and the stair climbing per formance requirements, distributing the number of teeth for each gear under transmission ratio requirements. Furthermore, modifying tooth profile parameters on each gear for improving the quality of the transmission. Using SolidWorks software established t he three-dimensional model. Then impact and contact simulated analysis is studied based on the SolidWorks Motion Plugins to get transmission and meshing condition. At the same time, gave the SolidWorks Motion output data as a result of the input data to t h e SolidWorks Simulation. Through the simulation results validate the output center gear tooth can meet the carrying capacity requirements. On the other hand, it also provides theoretical basis for further improve the structure design.

In recent years, our province occurs gas and coal dust explosion accident of coal industry producing process frequently. After the accident, rescue personnel can’t go down in time, waste precious rescue time, causing more casualties personnel. To solve this problem, try to design walking mechanism of the underground exploration robot with a strong adaptation to the complex terrain, climbing and crossing barrier ability, we use the software of MATLAB and ADAMS to establish the three-dimensional model of walking mechanism and the disaster area scene and inspect the walking mechanism’s traveling smoothness in the complex terrain. Through the simulation results, we can see that walking mechanism of the underground exploration robot has a good ability to adapt to changes of the ground, effectively regulate the relative balance of the main body of walking mechanism, suitable for explore the environmental information in the underground complex terrain.
