During the design of the second-phase extension project of a fuel electric plant in China, in order to meet the technological requirements, a typical oval steel coal scuttle with double funnels was proposed. This kind of scuttle has a complicated geometrical shape and is difficult to be designed and built. To evaluate the mechanical behavior of this scuttle, the 3D finite element structural analysis...
Feature-based solid modelling systems has been widely use in product design. Ideally the models generated within these solid modelling systems can be reused in downstream operations, such as finite element analysis. However, for engineering analysis an abstracted model is usually more appropriate, in term of accuracy and efficiency. This paper describes an automated approach to approximate an abstract...
Connecting rod mechanism is an important consideration in the design of Diesel Engine. But it is difficult to describe the dynamic changes of boundary conditions of the running engine by the traditional method of simply finite element analysis. In order to obtain the vibration characteristics and vibration frequency distributions, structural characteristics of the connecting rod mechanism using modal...
This paper put forward a framework of computer aided design system of customized insoles. We build a three dimensional model of the foot and insoles via scanning technology. Biomedical parameters were got by pressure distribution system Xsensor and gait analysis system Footscan. Then we get the boundary conditions of customized foot and insoles. The results of design show that the pressure in the...
Four process parameters including, the pad length, the pad width, the stencil thickness and the stand-off, are chosen as four control factors, and by using an L25(56) orthogonal array, the no-fillet chip component solder joints shapes with 25 different process parameters combinations are established. And then all the shape prediction models of the 25 solder joints are built through the Surface Evolver...
