Abstract


With the improvement of computer’s capability, virtual prototypetechnology has been devdloped rapidly. The necessity of studying this newtechnology in our traditional industry is of evidence and urgency owing tobeing integrated by many advanced method and technology, shorteningdevelopment cycle, reducing product cost and increasing enterpriseefficiency.This thesis deals with the problem of developing the Palletized LoadingSystem (PLS) Vehicle. Instead of traditional methods, virtual prototypetechnology is introduced into this field and several advanced tools are used,such as ADAMS etc. It is focused on theprogress of developing and containsthe following contents:Firstly, according to the requirement we make a primary framework of thestructure of the PLS and hydraulic system in which the shape and size of eachcomponents of the system is determined. Based on this framework a 3D modelis built in Pro/E environment.Secondly, by exporting Pro/E data into ADAMS, a virtual prototype of PLSis achieved. This virtual prototype is able to be used to imitate the movementof the system and calculate the load of major part such as oil cylinder etc.Obviously it can provide guides for choosing the appropriate oil cylinder.Finally, based on the virtual prototype we develop FEA model for caredcomponents in Ansys environment in which we can analyze the stress of majorparts of the system in different working conditions and find the unsafe part.With the result of analysis we can optimize the key parameter and improve thestructure of the system.Thus the aim of this thesis to build a more efficient framework to designa PLS is achieved.
