Box Structure

As the main load-bearing structure of heavy machine tools, cranes, and other high-end equipment, the large-scale box structures usually bear moving loads, and the results of direct topology optimization usually have some problems: the load transfer skeleton is difficult to identify and all working conditions are difficult to consider comprehensively. In this paper, a layout design method of stiffened plates for the large-scale box structures under moving loads based on multiworking-condition topology optimization is proposed. Based on the equivalent principle of force, the box structures are simplified into the main bending functional section, main torsional functional section, and auxiliary functional section by the magnitude of loads and moments, which can reduce the structural dimension and complexity in topology optimization. Then, the moving loads are simplified to some multiple position loads, and the comprehensive evaluation function is constructed by the compromise programming method. The mathematical model of multiworking-condition topology optimization is established to optimize the functional sections. Taking a crossbeam of superheavy turning and milling machining center as an example, optimization results show that the stiffness and strength of the crossbeam are increased by 17.39% and 19.9%, respectively, while the weight is reduced by 12.57%. It shows that the method proposed in this paper has better practicability and effectiveness for large-scale box structures.

This study proposes a modular design method that considers defense from leakage of the synthetic function. Today’s modular design method might lead to an increase in of the leakage of intellectual property. If the modular design were able to conceal the structure of the interactions of product components which realize the product functions, the competitive value of synthetic function might be protected and its life might be extended in the market. The proposed method was implemented to a prototype system (the paper feeder on a photocopier). The result showed the Pareto solution for the trade-offs of manufacturing cost reduction through outsourcing and the defense against the leakage of synthetic function value, indicating a module division plan with both aspects balanced at a high level. The comprehensive evaluation confirmed that the proposed balanced plan accounted for a more satisfactory evaluation value than the other two plans. Specifically, the study recommended the module division plan that enables around a 74% reduction of risk of leakage of synthetic function and about a 43% overall loss, even though the manufacturing cost worsened by approximately 42% when compared to the plan emphasizing manufacturing cost reduction. These application results support the hypothesis that modular design can conceal the structure of functional interactions. Therefore, it was concluded that the proposed module design method was more effective than the existing method, which does not consider the hiding and concealing of the functional interactions of the synthetic value.

ABSTRACTGardening is an activity cultural ancestors which has been passed down from generation to generation that is on the face of this earth until humans are present. Gardening can not only be done on vast land but also in the yard of the house. The large number of garden tools such as sputters, chainsaws, sekateur, hand scrapers, hand forks, and machetes. carrying a special bag to make things easier bring the equipment is before the equipment is only placed in a backpack along with other equipment, so it must be unpacked when the equipment will be used. then often every time using gardening tools but after wearing it we sometimes forget to put and left behind after being used to scattered and cluttered everywhere.Therefore it is necessary to create special means to carry and tidy up the plantation equipment. The design method used is collecting data, analyze the data, determine the design concept, create alternative design, developing alternative designs, to final design. To that end, with the "design of plantation tool bag", users can carry and store gardening equipment, with a more ergonomic design, and aesthetically modern.Keywords: gardening, bag, take, tools.
