Dynamic Analysis Of Coal Pre-homogenization Shell Subjected To Moving Loads

With the rapid development of our country’s construction technology and the need ofpeople changed, also the more and more demanded for the building space,spatial structure asa symbol of life to reflect the region and meet the production of people has been widely used.With rapid development for the spatial structure of technology, and more and more novelform of spatial structure, as the span is increasing, the problem of large-span structures for thevibration and disaster prevention cannot be overlooked.Now especially as the needs of industrial production, the use of the spatial structure ofpower equipment such as cranes and other large-scale production and the large mobilehanging load which used may relate to the personal safety, leads structure of the dynamicresponse cannot be ignored. At the same time, these large-span structures, and most importantbuildings, equipment, valuable, and also in high-altitude, appeared more difficult to repairdamage, leaded to large impact on production, if there are problems will have immeasurableloss. Necessary to be thoroughly accurate simulation and analysis, understand the impact ofits structure, take the effective design of methods to eliminate the root of the problem.Based on the above background, we take the coal pre-shell as the model in connectionwith the large-span structures used in industrial production, analysis the effect of movingloads in the dynamic performance, based on a variety of factors to consider and practicalresearch purposes, through the shell of the top hanging mobile devices of thepre-homogenization of raw materials to transport raw materials analysis, without affecting thestudy results and achieve the premise purpose, we will simplify the analysis:(1) Under the moving force, we analysis the internal force distribution regularity of thewinding, last quarter, the vertical bar, and the belly bar in the double-layer cylindrical gridshell, and get some conclusions of practical significance.(2) Under the vertical moving harmonic loads, we analysis the internal force distributionregularity of the winding, last quarter, the vertical bar, and the belly bar in the double-layercylindrical grid shell, and get some conclusions of practical significance.(3) In the horizontal moving loads, we analysis the internal force distribution regularityof the winding, last quarter, the vertical bar, and the belly bar in the double-layer cylindricalgrid shell, and get some conclusions of practical significance.(4) The internal forces of various parts of the bar were compared under the vertical andhonrizontal moving loads and moving harmonic loads. Obtained the internal forcesdistribution regularity under the moving load.(5)Analysis the dynamic regularity of the cylindrical grid shell under the loads of thecranes.
