Fatigue analysis for connecting rod of reciprocating piston compressor

摘要

Three-dimensional modeling software and dynamics simulation software were used for fatigue design of the connecting rod. Dynamics simulation model of crankshaft system was established and the load of connecting rod was obtained. Non-linear contact analytical method of static strength was adopted to accomplish the stress distribution of the connecting rod. On the basis of the static strength analysis, fatigue life and fatigue safety factor of the connecting rod were get by fatigue strength analysis. Compared with experiment and engineering calculations, co-simulation method of multi-software is more economic and accurate. Furthermore, optimal design of the connecting rod would be benefit from the calculation results.
