Optimal Design of Safety Valve Spring


Article Preview

In this paper, it aiming at the functional features of containerization canning safety valves adopts the method of design of experiments (DOE) to conduct fast modeling on the working conditions of the safety valve spring, and cites the means of multi-objective optimization to optimize the spring designs, minimizing the maximum inner shear stresses of its winding coils and its weights. In the process of the study, a parametric finite-element spring model with three variable parameters has been used to generate arbitrary spring shapes within the pre-set scope of spring shapes.By the V-Optimal method, it generates a DOE input matrix with 30 input points. It obtains a two-third-order polynomial regression model through analyses and calculations, which can fully reflect the regression characteristics of the shear stresses and the weights of springs. This study shows that by means of DOE and multi-objective optimization, it enables to quickly design and optimize on safety valve springs.
