Dynamic Optimization Design of the Opening and Closing Process of the Connecting Rod Mechanism of a Shutter
With the complexity of the functions of submersibles,the available space inside is highly limited,and the energy that can be carried is greatly limited.In order to reduce the energy consumption and space size of the opening and closing mechanism of the submersible anti-wave board,the stress state analysis was carried out for the opening and closing mechanism of the anti-wave board.The ADAMS dynamic model of the opening and closing mechanism of the anti-wave board was established by combining the hydrodynamic-opening function of the anti-wave board,and the variation law of the driving torque required for the whole process of the opening and closing of the anti-wave board was analyzed under the conditions of different structural parameters.According to the control variable method,the structural parameters that make the driving torque smaller in the whole process of opening and closing of the anti-wave board are obtained.The results show that:after adopting the optimized structure parameters,the maximum driving torque is reduced to 8.812 kN·m,which is 50.86%lower than the maximum driving torque of the existing structure(17.934 kN·m),and the optimization effect is more significant.The work of this paper comprehensively considers the dynamic force in the whole process of opening and closing of the anti-wave board,and optimizes the structural parameters with small driving torque in the whole process of opening and closing of the anti-wave board.This method is suitable for the whole process dynamic design of similar structures Instructive.
