【Abstract】 The continuous conveyer of disc-tube assembly is a new type for way of bulk solids’ transportation. It can’t only meet the transport task of high demand to the environment, with by taking a small less space, higher efficiency and lower cost; but also solve the difficult problem of long distant transportation for heavy powder material. The “Virtual Design and Experiment Study” synthesis design method is centralizing the advantage of “Dynamic Design, Visual Design and Scenario for Structure”, The method is very advanced with its aim to improve the product’s general quality. Through the analysis of static and danamic force in the driving system of the conveyer, it comes to a conclude it concludes laws about the laws of the velocity and acceleration in driving chain . In the direction of running and libration, we innovatly use the theory of fluctuation and string-libration, conclude the inherent frequency of x-direction and y-direction, and find the resonance point of the driving system. Besides, the dynamic model in driving system of the conveyer is established with through scattered method on no damping occasion. Visual design of the continuous conveyer of disc-tube assembly has been carried on with the method of “Virtual Design +Experiment Study”. The visual model of three-dimension of the conveyer has been set up. The finite element analysis and modal analysis of some parts have been made under the three-dimension model. To realize the visual process of the assembly, the analysis, appraise and amendment of the whole working performance of the conveyer have been carried on.And to realize visualization of the working process, the virtual movement emulation of the conveyer has been used in the emulation software. Making use of the “Virtual Design and Experiment Study” synthesis design method, we have carried on the experiment study of the continuous conveyer of disc-tube assembly, designed and manufactured the prototype to the conveyer. The torsion measuring system of drive wheel has been designed based on the prototype. And we succeeded in realizing measure online. Therefore, the research on the continuous conveyer of disc-tube assembly has important meaning in the theory and great value in application by making full use of the “Virtual Design and Experiment Study” synthesis design method.更多还原
