3D Simulator of a Rolling Baton on Cylindrical Surfaces
Summary form only given. We make physical analysis of a baton rolling on cylindrical surfaces and then present a 3D simulator which helps us design actual surfaces to be used for a physical performance and for an interactive entertainment system.
Baton Rolling on a Series of Curved Surfaces
We call an instrument that generates geometrically and aesthetically appealing spatio-temporal patterns through actual manipulation a visual instrument. We present a novel visual instrument that uses batons to roll on a series of curved surfaces. We fabricated a prototype of the instrument and confirmed that the batons can be smoothly rolled and manipulated on the surfaces and that the instrument leads to new types of rolling-based play and performances.
Numerical Simulation of Induction Heating Process of Continuous Casting Slab
Compared with traditional blazing furnace, the Continuous Casting-Direct Rolling is an advanced manufacturing steel technology, which can reduce energy waste, decrease pollution and enhance efficiency. The characteristics of steels during induction heating are complex, the change of material properties with temperature makes exact analysis methods very difficult to implement. Therefore, a powerful computer aided numerical tool (i.e., finite difference analysis) is selected to numerically model the induction heating process in this paper. The mathematic model coupling with electromagnetic field and thermal field was established, and it was solved by finite difference method (FDM), thus the slab temperature distribution and its variation with time were obtained, and the characteristics in whole induction heating process were studied. To validate the program feasible, the results were evaluated and compared with experiment results, which showed that the simulation results are reliable and effective. The skin effect in heating process from the two results was studied and demonstrated, the temperature change caused by different parameters such as the induced power intensity and the corner radian were also presented, which indicate that the slab temperature can be heated uniformly through adjusting these parameters, thus the continuous casting slab can meet the rolling requirement.
