The Static Analysis of the Parallel Bars of the Crankshaft of a Mini Air Compressor on ANSYS

Mechanical model of crankshaft and connecting rod mechanism of reciprocating compressor was built. Then the order of stress was obtained every ten degrees while crankshaft turning. The larger stress of crankshaft initial turnings was utilized to calculate the whole model and the unreliable region and destructive working condition then was determined. The situation was simulated with ANALYS and the static characteristics, i.e. stress and strain, of the crankshaft was also obtained. The simulated results testify the analysis and the results of the paper have great value for reference when designing crankshafts.
