The base plate should be repeatedly tested and modified in the design stage before reaching the specific requirements, resulting in problems such as high research and development costs and long design cycles. Keywords: mortar base plate, parametric design, sensitivity analysis.Īs the base plate is an integral part of the mortar, the rationality of the structure of the base plate has a significant influence on the shooting precision and stability of the mortar. Moreover, parametric optimization carrying out on results of sensitivity analysis could give feedback to parametric design for guiding parameter values of design variables to improve the design quality After conducting parametric analysis on the model established, sensitivities of design variables of the base plate have been analyzed using an approximate model in combination with the sample designed by the optimal Latin hypercube approach. Meanwhile, Python has also been applied in the secondary development of Abaqus, so as to realize the automatic finite element modeling of the base plate. By conducting characteristic analysis of the base plate, critical design parameters extracted have been driven as characteristics to perform secondary development on UG, so that the base plate could be automatically modeled in three dimensions. In order to improve the efficiency of designing and analyzing a mortar base plate, parametric technology has been applied to the design and analysis of the base plate.
