摘要:

An attempt is made to solve the Reynolds equation as a nonlinear equation for unknown film thickness ratio and tilt parameters. The film thickness is considered to be varying in circumferential and radial directions due to the roll and pitch motion of the pad, about the center of pressure obtained after the thrust pad is manufactured/assembled. The pressure profile obtained when the pad is in equilibrium is used to analyze the distortion of the spring-supported thrust pad. Such a type of analysis is necessary to predict the actual performance of a thrust pad bearing, since the thrust pad is not likely to operate with the initially chosen inlet/outlet film thickness ratio as a result of distortion. Hence, the center of pressure decided at the design stage will change with the operating conditions.
