The Reason And Countermeasure Research Of Crackle Engender In Pedestal Of Traveling Organization Of Crane

Material handling machinery is a machinery equipment which servered as material carrying, loading and unloading or used to install, it becomes from the assistant equipment of the manufacture department to the indispensable installation of manufacture mechanization and automation. it's condition greatly affects business production efficiency, It is also utmost importance to achieves the safe production. Hence, it has significant actual sense to analysis the malfunction of crane.The paper puts the WuGang cold roll mill crane of 0 as target, the crack of lap cover board of the traveling mechanism of the large traveler as research contents, applies the information of mechanics and basic principle to analyse the mechanism that takes shape to the crackle, the analysis stress is researched the mechanism that the crane crackle come into being by means of dynamics analysis and vibration mode. It chiefly carries on such researches:First of all, carry on the statics analysis to the girder, conclude that the crane fault was caused by local fault, Moreover, do some research on the relationship between the crane work loading and the influence of crackle takes shape on the traveling organization pedestal.Secondly, carry on the mode analysis to the girder, research the girder vibration property and the probability of crackle takes shape in the vibration effects of traveling organization pedestal.Thirdly, carry on thoroughly researching about the mechanism of crackle takes shape on the travelling organization pedestal with instantaneous dynamics, and unite the mode analysis result, find out the fundamental reason that the crackle takes shape, supply the theory sustain to the repair of traveling crane.Finally, utilize the large finite element analysis software ANSYS, Carry on the finite element model building and analysis calculation to the tavelling crane girder. Utilize APDL language to carry on parameterization model building and loading in this process, and analysis the techniques about the model simplifying. On the basis of the research, it has greate direction sense to the crane design, manufacture and maintain, and also to the accurately assess the crane operational performance and so on.
