Designing Complex Technical Means Using the Integrative Approach for Construction Optimization
Abstract:
Designing process is such type of engineering activity that needs to link systemized engineering knowledge with non-systemized method of heuristic concepts generation. To obtain the more predictable results it is needed to change the heuristic elements into more systemized ones. One of possible solution is to use the integrative approach. It bases on the previously proposed structure of any technical mean and on the breakdown of designing activities according to analyzed constructional forms. The structure includes such subsystems of a technical mean like: structural one, drive one and control one. Whereas the distinguished constructional feature includes: geometric one, material one and assembly one. By proper joining the subsystems and constructional features it is possible to manage a designing process in the more effective way. In the paper is presented the formalized method of designing that utilizes mentioned integrative approach. The formalization allows conducting a designing process according the uniform set of rules. The proposed approach was applied for designing specific hydraulic systems. In the paper is presented its application for designing the new system of canopy movement for a mining mechanized support. The purpose of conducted project was to eliminate the unwanted movements of a canopy in the horizontal direction. Using the integrative approach it was possible to design the straight-line mechanism. It led to move a canopy only in the vertical direction. From the system point of view in this mechanism were eliminated the rotational kinematic pairs. Instead them it was used a sliding pair in a form of a square guides. The applied solution allows simplifying the construction of a support and also decreasing its weight. And this, in turns, leads to an increase of durability. From the perspective of the whole life-cycle of a mining support, as a specific technical mean, it results in significantly lower total costs.
