Alternative solutions used fixed-bearing designs, which increase stability and reduce the risk of bearing dislocation, but with a theoretical increase of contact stresses leading to a higher polyethylene wear. The purpose of this study was to investigate the contact stresses, pressure and area in ...
A water pump bearing is a device used to support the end of the water pump impeller shaft. Fitting securely around the impeller shaft and tightly into the water pump housing, the water pump bearing is designed to withstand the stress and load placed upon...

The model built in this chapter is a cylinder with a diameter of 3 meters and a depth of 1 meter. Plane55 was used in the calculation of temperature field in the early stage, and solid70 unit was later converted to plane42 and solid45 unit in the calculation of stress field, with a...
MO-ASMO algorithm is used for solving the problems of fluid and texture design with two targets at the same time. In the case of low performance computing resources, MO-ASMO algorithm can achieve accurate solutions. Because of the stability of NSGA-II model, the combination of some texture ...
provide hydrodynamic pumping action in the hemispherical fluid bearing layer, which is sealed by surface-tension at the edges of the hemispherical ball-and-socket clearance. However, Titcomb et al do not consider solutions to the fluid seal and leakage problems related to bubble-entrapment and ...
It was determined that uncured PTFE tapes offer much higher plasticity and flexibility, improving their capacity for impregnation with minimum stress on the material. Using this approach required the implementation of a second process to cure the filled PTFE layer following impregnation, ensuring ...
BEARING CAPACITY OF FOUNDATIONS (承载力的基础).pdf,CHAPTER 4 BEARING CAPACITY OF FOUNDATIONS 4-1 INTRODUCTION The soil must be capable of carrying the loads from any engineered structure placed upon it without a shear failure and with the resulting se
In this paper, the multi-scale method and piecewise-linear technique deduced the second-order approximate solutions. Chang-Jian and Hsu [13] performed a systematic analysis of the dynamic behavior on the gear system considered the nonlinear suspension, nonlinear oil-film force, turbulent flow effect...
These solutions are rigorous upper-bound ones with respect to the exact solutions for an associated ?ow rule Coulomb material. In this paper, both the static and seismic bearing capacity problems are investigated by the upper-bound method of the limit analysis theory using respectively symmetrical ...
