| Sequential optimizaton of mechanical motion behaviors is an important stage for mechanical optimizational design. Presently, the computer aided sequential optimizaton for this stage is still at the beginning due to several reasons such as modeling method,process model and representation methods. Based on an example of Zongzi automatic binding machine , this thesis made an in-depth research on the motion behavior sequential relations and the automation methods for original motion behaviors, established building rules and the expressional methods based on overlapping net representation method. The researches are carried out as follows:1. The rules of series relations and the mathmatical model are researched to accomplish the computerization for the original grouping of behaviors to get the original behavior structure, with zongzi automatic binding machine as an example.2. The methods of overlapping network expression for behavior structure are researched. The behavior sequential relations is expressed by overlapping network and the model is researched.3. Taking coordinated movements as the basement for the sequential optimization of behavior structure, the motion relations of behaviors are defined to restrict the relations of different groups, to realize the optimization of behavior structure. 5. Analyses every behavior node and establishes time parameter for all nodes to build the mathmatical model of computerization for overlapping network to mechanical motion cycle graph, and studies how to embody the motion cycle graph. 4. Studies the major factors that has important effects on behavior structure and researches how to evaluate the behavior structure.Besides, evaluating methods of actuator scheme has been studied and the rule of forming actuator scheme has been established.Based on an example of Zongzi automatic binding machine , this thesis made an in-depth research on the motion behavior sequential relations. The consquence indicates that the design process and the work efficiency is improved, while the appearance is more pretty. |
