While WEC damage can be mitigated by avoiding reactive lubricant additives, Paladugu notes that the lack of the reactive additives might result in other problems such as micropitting of gears and bearings. Chemically modifying the steel surfaces at the rolling contact is one way to avoid WEC damag...

A significant number of unexpected problems and challenges occurred during the project, though it was possible to establish a plan to systematically address and resolve these issues. These problems extended the project timeline, however, causing some delays. Centering the Voice of the Customer While e...

The non-dimensional second order differential motion equations are difficult to solve by conventional perturbation methods, therefore the fourth order Runge-Kutta method is applied to obtain the numerical response solutions of the system. 3. Nonlinear characteristics of the rotor-seal-bearing system The...
Although the strength of sand is related to the stress level, the non-dimensional factor, γ′Htanφ/s , can be simply taken to indicate strength ratio between s u the sand and clay. Here γ′sHtanφcan be taken as the initial strength of the sand at the layer interface. The above ...
number of microorganisms that can be injected and thrive in the formation. Biological constraints, such as competition from indigenous microbes and the stress of changing environments (from surface to subsurface) also act to limit the viability of exogenous microorganisms. To overcome these problems,...
It is the nature of coatings grown by PVD or CVD processes to have compressive stress, which scales with the thickness of the coating. There are many reasons for this, but the scaling many times depends upon the difference in the elastic moduli of the coating and the substrate. For B4C,...
3. A method for mounting a sliding bearing as set forth in claim 1, wherein in said pressing step, the force pressing the outer circumference around said shaft sliding portion of said bearing in a radial direction is a stress with which the level of inward shrinkage in a radial direction ...
The object of the present invention is to provide a bearing shell for a ball and socket joint, based on the problems described and the possible solutions to these problems, which have been known from the state of the art so far, such that strong forces in one load direction can also be...
