Configuration Synthesis of Actuators for Underwater Vehicles' Receiving and Placing System
Aiming at the problems of single structure form and limited transporting range of existing underwater vehicles
receiving and placing system
this study carries out comprehensive research on actuator configuration of the receiving and placing system with the help of relevant graph theory
and finally establishes 14 actuator configuration libraries of the receiving and placing system. Firstly
the types of the planar nine-bar single-hinge mechanism are synthesized based on the method of blastogram insertion
and 40 kinds of monochrome topological maps are obtained. Secondly
based on 40 kinds of monochrome topological maps
a method for synthesizing planar nine-bar mechanism with only one type of complex hinge mechanism is proposed. By transforming the monochrome topological map and its specific markings
and generating feature array of the complex hinge mechanism according to certain rules
the mechanism isomorphism judgment and negative sub-link recognition are realized based on the feature array
and 83 kinds of bi-color topological maps are obtained. Then
based on the flat nine-bar single-color and two-color topological map and combining the operating characteristics of the collection system
six configuration screening conditions for the implementation mechanism of the collection system are proposed and 71 feasible configurations are selected. Finally
based on 71 feasible configurations and considering mechanism control
cost and aesthetics comprehensively
three configuration optimization criteria are proposed
and 14 optimal configurations are finally obtained. An optimum configuration is selected for motion simulation analysis. The results show that the actuator of the new placing system meets the operating conditions
the end integrated hoist can achieve far and near displacement and accurate positioning
and the rationality of the mechanism configuration design is verified.
