    This research aims to examine the compound impact of adding rectangular textures to various zones on the surface of the bearing and nanoparticles in the lubricant on the properties of journal bearing. A lubrication models with various texture depths and eccentricity ratios of journal bearing are created and simulated using CFD-FSI method to get static properties like load capacity and frictional force. Aluminum oxide nanoparticles were added in weight ratios ranging from 0.1 to 0.5 %, and the change in viscosity due to these additives in the lubricant was considered. Cavitation and the dependence of viscosity on temperature effects are also considered. The validation results show that the acquired results from the current simulation method agree well with the experimental results in the reference. The outcomes indicated that the highest load capacity and the lowest frictional force are found in the high-pressure region. It was noted that the maximum rise in load capacity was 16.51% without nanoparticles at a texture depth of 0.5 mm and eccentricity ratio of 0.1, and with the adding of 0.5 wt. % of nanoparticles to the lubricant in the same region, the load carrying capacity increased to 40.87 % compared to a bearing without textures.

    This paper exhibits a study of car passive and active- suspension system to improving drive exhilarate to passengers while also enhancing vehicle stability by decreasing the effect of oscillation on the suspension. Modeling and simulation by using the bond diagram. They much concede a prime arrangement of the machine to the exterior surrounding: street quality, atmospherically circumstances, while guarantying driver as well as passengers, major safeness and more potentially exhilarate. Automotive aid it course manners. The result cleared this action plan at different set during the vehicle mean, but particularly in evolution level. It is also clear the proportion of suspension system's mass to the vehicle's mass. Also graphical representation of suspension system' parameters like vertical passenger displacement, potential energy of mass of suspension system and acceleration. To foretell the comportment of a car, it is necessary to make design, modeling, and simulation. Honda Civic Lx 2019 sedan car has used for modeling, and simulation.
  • Investigation of cavitation in a finite journal bearing considering the journal speed and couple stress fluids effects

    Tribology in Industry, 2018
    A theoretical analysis of the combined effect of journal speed and couple stress fluids (CSF) on the performance characteristics of a cavitated finite journal bearing (FJB) has been presented in this paper. Depending on the Elrod cavitation algorithm (ECA), the solution to the modified Reynolds equation is achieved. The bearing parameters are affected by both the journal speed and CSF. From the results obtained, it is detected that the nonNewtonian lubricants (CSF) produce enhanced in the fill-film pressure, load-capacity, as well as reduces the Sommerfield number and a small drop in the values of the bearing side leakage flow. The results obtained in this work specify that the characteristics of the bearing are affected significantly by this effect. The achieved results have been compared with that published by other works for the bearing operating with pure lubricant and showed to be in a good agreement. © 2018 Published by Faculty of Engineering Corresponding author: Mushrek A.
