This paper presents the investigation into the tooth profile features, meshing characteristics and the principle of forming circular arc tooth race cylindrical gears (CATT gears). Based on the meshing theory of the curvilinear gear, tooth surface equations and meshing line equations of the gears and rack shave been established. The graphical analysis of these equations shows meshing performance...

The use of Object Oriented Programming (OOP) for automatic mesh generaton for Finite Element Analysis is presented in this paper. Aspects related to the geometry definition, meshing characteristics, triangular elements generation, data structures and implementation aspects are also discussed. Graphical examples generated by C++ code running on a PC are also included to illustrate the concepts a...

Meshing is a popular technology for feature extraction in handwritten Chinese character recognition. In this paper, we propose a hierarchical overlapped elastic meshing (HOEM), which integrates overlap, fuzzy membership and hierarchical division into elastic meshing. The overlapping zones and the fuzzy memberships of the pixels in each zone are dynamically calculated through mapping the input i...

This paper describes the automatic generation of a structureddominant mesh based on an automatic block decomposition obtained using the medial object. The mesh generator will produce a mesh for an arbitrary two-dimensional geometry, where quadrilateral-dominant or triangular meshing is used when structured meshing fails. The domain is automatically partitioned into blocks (sub-regions), and an ...

Recent research on friction in robot joints and transmission systems has considered meshing friction a position-dependent friction component. However, in this paper we show experimental evidence that meshing friction depends highly on joint speed. We identify the meshing friction in the gearboxes of a robotic leg, and we propose a new mathematical model that considers the rate dependency of mes...

A complete method is proposed to compute a certified, or ambient isotopic, meshing for an implicit algebraic surface with singularities. By certified, we mean a meshing with correct topology and any given geometric precision. We propose a symbolic-numeric method to compute a certified meshing for the surface inside a box containing singularities and use a modified Plantinga-Vegter marching cube...
