In allusion to the technique requirements such as reliably open, enough and greatly open-angle, automatically open or lock for the pressure tank, a method using function cycle time combination, and spatial multi-link coupled actuating strategy is proposed to develop a spatial multi-link Mechanism with a variable revolution axis to ensure of perpendicular inside out opening rapidly. A parametric dynamic model is established, the opening angle, horizontal size of the opening mechanism, and erecting cylinder load are used as outputs, and the Hinge-point parameters of the links are taken as inputs. Nondominated sorting genetic algorithm is used to solve the multiobjective problem and the max-min criterion is adopted to select a solution from the Pareto front. The optimized effect is compared with the results of ADMAS dynamic simulation, scale experiment and product experiment tests. The result shows that the proposed method provided a certain reference for optimization of perpendicular inside out opening mechanism.
