| Summary: | This thesis describes a comparative study between analytical method and
finite element method of a cylindrical bore journal bearing behaviour. In calculating
the performance characteristics of a journal bearing such as pressure distribution,
load capacity, flow requirement and power loss, isothermal analysis was carried
out. Using both analytical method and finite element method, the effects of
variations in operating variables such as eccentricity ratio and shaft speed on the
bearing design parameters were calculated. With regard to CPU time, analytical
method performs better than finite element method; but in terms of obtained
results, finite element method shows better performance than analytical method.
The analytical results and finite element results are compared. In order to check
the validity, when these results are compared with the available published results,
on the whole, finite element results show better agreement than analytical results. |
