ESDU 92034 provides details of a Fortran program provided on disc in the software volume (ESDUpac A9234) both uncompiled and compiled within ESDUview@ a user-friendly interface that prompts on-screen for input data and runs under MS DOS. It implements the calculation procedure of ESDU 82029. It allows performance analysis of an existing design@ or the design of a bearing to meet selected performance requirements in which case suitable bearing dimensions@ subject to any space constraint@ are recommended. The predicted performance includes the lubricant film thickness under load@ its temperature and flow rate@ the power loss@ and the bearing temperature. Recommendations are also made on surface finish. Warning messages are output in the following cases@ for each of which possible remedial actions are suggested: drain or pad temperature too high@ churning losses too great@ film thickness too small@ pad number too high@ ratio of inner to outer pad radius too large@ flow rate too great@ lubricant or pad temperature outside usable range. A lubricant database is provided that may be extended or edited. The program applies to Newtonian lubricants in laminar flow. Worked examples illustrate the use of the program.
