Design for Manufacturing and Assembly (DFMA) of a test bench to simulate mechanical vibrations in rotating equipment

In the last decade, the reliability and safety of industrial processes have played a very important role in ensuring competitiveness of national and international companies, requiring on-line and off-line fault detection systems that appear in normal operation, and in other cases, the implementation of more robust methodologies for potential failures. Two of the problems that usually occur in the rotary equipment are the mechanical misalignment and imbalance caused mainly by errors in the assembly, non-uniformity in the density of the material, tolerance in the manufacture of parts, which cause great damage in the machines and generating vibrations that cause problems such as heating parts, increased hot oil, increased lubricant dripping through seals, premature failure of bearings, seals, shafts and joints, wear and tear of parts, loss of efficiency in the engine, noise and collateral damage among others The results of this research provide guidelines for the design, manufacturing and assembly of a test bench to simulate misalignment and imbalance failures under controlled conditions by measuring and monitoring selected variables for study, take into account the benefits of Maintenance Condition Monitoring (CBM) and Design for Manufacturing and Assembly (DFMA) methodology.
