The frequency characteristics of the radiators of ТМ01 and ТЕ01modes of a circular metal waveguide are investigated. Radiators in the form of an open end of a circular waveguide with a stepped cut, including those with a cylindrical mirror, as well as an open end of a waveguide with an inhomogeneous anisotropic dielectric plate are considered. Numerical simulation and optimization of parameters were carried out using finite element and finite differences in time domain methods.

Abstract This paper extends the finite element simulation scheme to handle the problem of tires undergoing sliding (skidding) impact into obstructions. Since the inertial characteristics are handled by the algorithm developed, the full range of operating environments can be accommodated. This includes the treatment of impacts with holes and bumps of arbitrary geometry.

The paper presents the results of research on the study of the elastic deformation of a flexible wheel from a double harmonic transmission, under the action of a cam wave generator. Knowing exactly how the flexible wheel is deformed is important in correctly establishing the geometric parameters of the wheels teeth, allowing a better understanding and appreciation of the specific conditions of harmonic gearings in the two stages of the transmission. The veracity of the results of this theoretical study on the calculation of elastic deformations and displacements of points located on the average fiber of the flexible wheel was subsequently verified and confirmed by numerical simulation of the flexible wheel, in the elastic field, using the finite element method from SolidWorks Simulation.
