The study employed the finite element method to develop a validated theoretical model to investigate the distribution of thermal hoop stress around the teeth of a spur gear operating in a filler machine. Three cases of temperature distribution along the radius of a gear tooth were assumed and investigated. The outcome showed that the maximum effective stress occurs at the tip of the gear tooth ...

The transform relation between the meshing position and rotation angle of a cylindrical gear pair is firstly derived according to the theory of gear meshing. Then the technique of building the assembly model of a cylindrical gear pair at specified meshing position in ANSYS is researched. On this basis, a new method to perform static contact analysis of cylindrical gear at any meshing location i...

A computational model of a planetary gear set is employed to study the influence of surface wear on the dynamic behavior of a typical planetary gear set. The overall computational scheme combines a wear model that defines geometric description of contacting gear tooth surfaces having wear and a deformable-body dynamic model of a planetary gear set. The wear model employs a quasi-static gear con...

This conceptual paper reviews a large number of literatures in terms of packaged enterprise system adoption and implementation in China. Three types of misalignments between packaged ES and Chinese context are identified, including (1) package-context misalignment in terms of software application, (2) package-context misalignment in terms of organizational management model, and (3) package-cont...

Existing polar transfer alignment (TA) algorithms are designed based on linear Kalman filters (KF) to estimate misalignment angles. In the case of a large misalignment angle, these algorithms cannot be applied in order to achieve accurate TA. In this paper, a TA algorithm based on an unscented Kalman filter (UKF) is proposed to solve the problem of the large misalignment angle in the polar regi...
