The results show that the heating temperature of induction heating meets the demands of steel plate bending, and the deformation of a steel plate heated by induction heating can achieve the same effect as flame heating. Meanwhile, the finite element model of moving induction heating of the plate is developed, and the comparison of the residual strain fields and transverse shrinkage between these two kinds of heating shows that great similarity has been achieved.展开更多

We prove that, in multiagent domains, convergence of the Q values is guaranteed only when an agent behaves optimally and its opponents’ strategies satisfy certain conditions, and an agent can get best learning performances when it adopts the same learning algorithm as that of its opponents.展开更多

During the honing process, the tool, equipped with one or several abrasive honing stones, combines three movement components： rotation, oscillation in axial direction and radial feed movement of the honing stone. The feed movement is a decisive factor for the results of the honing process and can be controlled either by a gradual lining in fixed time intervals or by the regulation of the occurring forces. The presented studies show different approaches for the regulation of force controlled honing and their effects on the measured forces, the torque and the quality parameters of the process.展开更多
