Finite element design optimization on mechanical joint considering reliability and robustness

To obtain the optimal product design from the engineering point of view, finite element structural optimization is performed on mechanical joints considering optimal structural parameter configuration under stress constraints. A theoretical result is obtained by finite element computation software Abaqus; considering the reliability and robustness generated by manufacturing tolerances and material property fluctuations, the structure parameters are analyzed and redesigned to perform the optimal structural parameter configuration by OPTIMUS. An example shows that the method has some practical value.
