The Mechanical Properties Investigate Of Impact And Buffer

At the present, the related buffer products used in industrial, civil facilities and other fields are mostly single element. This paper is based on the binary buffer theory and the dynamic model of a new buffer device, and studies its mechanical charateristics of impact and the buffer.New type buffer device based on the principle of bionics absorbs the impact energy by the combining spring and gas component. Firstly, this study applied the basic theory of kinetic energy and momentum and established collision dynamics model. Secondly, in the impact experimental study, apply the method of modern photomechanics to obtained study data of impact and buffer of the physical model. With the analysis,control and optimization of the deformation, buffering capacity to the model of new buffer device in impact, we study the mechanical charateristics of impact and the buffer of new buffer device. Finally, based on the further study on the properties of collision and impact in the work process of new buffer device, we find that the area of end cap discharge hole is the key parameter to control collision force, and the collision force is controllable in certain area, and find the best work area, which has important practical significance for the perfect buffer effect of new buffer device.In order to put the new buffer device into the actual construction of large sluice gate, according to the similarity theory, the author establishes the similarity relation of the model and the real of two-component buffer device, and designs the important parameters of the real structure, it simplifies the structural design in complex buffering problems. This not only gets theory into practice, but also deepens the understanding of mechanical characteristics in the impact and buffer territory.
