The Finite Element Analysis And Research Of Ladle Furnace Buggy's Structure

In our country,along with the continous foundry ratio is large scale enhancement,the Ladle Furnace also rapidly develops,becomes the contemporary most main the fining equipment of the converter outside.The ladle furnace buggy is one kind of essential transport vehicle outside the stove in the fining.In order to satisfy the safe-fast production,the design request of ladle furnace buggy more and more is also high.In our country,the design and the intensity examination of the frame is depends upon traditional experience and method,it is very easy to do,at present it still played a certain role in vehicles,design and calculation in our country.Because the empirical design has the suitable blindness,each time the frame design improvement cannot have the obvious breakthrough:Moreover design time long,causes the frame the renewal speed quite to be slow,each part of the frame intensities assignment is unreasonable.Because the design method of experiences analyzes is insufficiency,the customer need one kind reasonably design method to reduce the weight of the frame and raise the market competition,enhances the company benefit,promote product scale. In this article finite element method is used to buildthe parameter model,may realize the overall rigidityand the stress analysis and the optimized design of the frame structure.In this paper first the design method of the traditional experience analyze is done, the design project of ladle furnace buggy is decided.The main work of this paper is use SolidWorks to design three-dimensional entity of the ladle furnace buggy Meanwhile along certain order assemble these parts. According to actual circumstance of the ladle furnace buggy,has established the finite element analysis model,exert the load and the restraint,uses finite element analysis software COSMOS/Works to carry on the static analysis to the frame,finally obtains the stress and the strain nephogram of the ladle furnace buggy,has determined the hazard point and the dangerous section;Finally experimental study is used to examinate the designed frame.All the studies in this paper not only offer some references and gists for the design of the frame,solved process actual problem of the factory,but also offer a new idea and some actually method,has provided beneficial trial to being similar to the design of the ladle furnace buggy.
