As the most important working area of gear, teeth play the role of transmitting load and power. Tooth line and tooth profile are the two main characteristics of the tooth surface, which affect the shape of the tooth surface, tooth meshing characteristics and contact characteristics. Taking the elliptical cylinder gear pair in the reversing device of a new type of drum pumping unit as the resear...

Abstarct In this paper, a new approach to optimize an Autonomous Underwater Vehicle (AUV) hull geometry is presented. Using this methode, the nose and tail of an underwater vehicle are designed, such that their length constraints due to the arrangement of different components in the AUV body are properly addressed. In the current study, an optimal design for the body profile of a torpedo-shaped...

We study the charge profile of a C60-FET (field effect transistor) as used in the experiments of Schön, Kloc and Batlogg. Using a tight-binding model, we calculate the charge profile treating the Coulomb interaction in a mean-field approximation. At low doping, the charge profile behaves similarly to the case of a continuous space-charge layer and becomes confined to a single interface layer fo...

This paper reports a sensor system which it has been designed and constructed to acquire the profile of surfaces. This system is based in a CCD camera for object boundary-determination mounted over a robot manipulator shoulder and ultrasonic sensors for depth measurement mounted on a fixture at the wrist of the manipulator. It has been used an average weighted by degrees of confidence for raw s...

We have proposed an optical method that can be applied to in-process or in situ measurement of the microsurface profile. The present method is based on optically performed spectral analysis and the phase retrieval technique. Spectral information of a surface profile is obtained by measuring the Fraunhofer diffraction intensity. The phase retrieval technique is used to reconstruct the surface pr...
