  Author(s): Verma AVerma A
  
  Unsteady transient analysis is carried out for hydro-dynamically lubricated journal bearing with infinitely long approximation. The performance characteristics are investigated by oscillating the journal velocity as a ‘sine’ function of the angle for which the journal rotates with an angular speed. Results comprising of Minimum lubricant film thickness, Dynamic pressure and load, Wall shear stress, Eccentricity, Temperature distribution and heat flux with respect to time are presented in the analysis graphically with the aid of ORIGION PRO 8. The journal bearing is analyzed in ANSYS 14.0 ‘Transient Thermal’ package. The journal is modeled as a “moving wall” with an absolute rotational speed of 3000 rpm. Appropriate equations and numerical solutions (Simpson’s 1/3rd integration rule and Newton-Raphson method) are developed using ‘C progra.. View More»
