Computation of 3D Electrostatic Fields Excited by Thin Conductors
Karban, P. ; Škopek, M. ; Doležel, Ivo
Solution of 3D electric fields in a system of thin charged conductors of general shapes by classical differential methods (FDM, FEM etc.) is extremely difficult due to ignorance of boundary conditions and existence of geomertically incommensurable subdomainswithin the investigated area. Application of integral methods is also complicated because the kernel functions occuring in the first-kind Fredholm equations are intergrable only in 2D and not in 1D.
Integral Solution of Electrostatic Fields in 3D Arrangements
Hamar, R. ; Doležel, Ivo ; Ulrych, B.
The paper deals with computation of 3D electrostatic fields (distribution of charges, electric potential and other derived quantities) by means of integral equations and their numerical solution. Selected are neither configurations that can be simplified to 2D problems and solved analytically, nor arrangements that might be processed by the FD or FE techniques. Analysed are fundamental mathematical aspects of the method, which is illustrated on a 3D field between two cubes in general position.
Computer Modelling of Induction-Heating Based Fixing of Machine Tools
Musil, L. ; Doležel, Ivo ; Ulrych, B.
The paper deals with numerical modelling of fixing machine tools - particularly auger drills in high revolution drilling machines - by means of the thermoelastic displacements caused by induction heating of the fixing chuck spindle.
