Numerical study of structural integrity and strain response of double end beam load cell using finite element simulation

Finite element simulation had been used to assess the structural integrity and strain response of double end beam load cell. The purpose of the study was to analyze the mechanical strength and to predict the class of measurement accuracy of the load cell design before manufacturing the physical prototypes. Based on the analysis of structural integrity, the safety factor of the structure was still in acceptable limits. Therefore, the structure would certainly be secure against both plastic deformation and ultimate failure. Based on the strain simulation results, the level of measurement accuracy was predicted to reach the medium class with a good repeatability of the measurement.
