In recent years, with the rapid development of the harbor transportation, a newtype of transport equipment, self-loading container truck, has gradually replaced thetraditional transport machinery as well as the preferred transport equipment of somefreight companies. Self-loading container truck is a kind of special container transportmachinery whose devices can easily handle with self-loading and unloading situation.It is characterized by its smooth operation and highly economical adoption. Thus it ispractical for places where lack of container handling equipment. This systemabsolutely achieves the target of effective "door to door" transportation technique.However, despite that the domestic research in the related fields is still in its infancy,the research is confined to the traditional experience and preliminary finite elementanalysis which greatly retards the independent development.The traditional finite elements analysis procedure is:1. Modeling in detail foreach structure of the vehicle via HYPERMESH software;2. Importing the files toANSYS software and apply boundary load and constraints;3. Finite element analysisand extract results;4. Optimize the dangerous parts;5. Remodeling and analysis.Throughout the whole analysis process, pre-process is a tedious and time-consumingtask which restricts the speed of product research and prolongs development cycle.Based on this specialized structure, put forward a series of modeling scheme with fastspeed and high precision, this paper has great research significance.To solve this problem, this paper employs ANSYS parametric design languageand puts forward the thought of full parameter adaptive modeling into the process ofthe finite element analysis of self-loading container truck. With the designcharacteristic of three levels as units, components and container truck, the simplifiedstructure convert into specified finite element modeling consist of beam, shell, link,entity and connection units.Secondly, depending on the theoretical calculation, this paper propose referenceand criterion for measuring the result precision of parametric analysis. Then comparing the traditional FEA with parametric analysis based on a certain typeself-loading container truck, we come to a conclusion that parametric finite elementsanalysis could not only accelerate the process of product development, but alsoguarantee the accuracy of the vehicle analysis resultsAgain, faced with the problem of larger structural stress during the process offinite element analysis, this paper arises a fast optimization method to enhance theexisting parametric model. Using stiffness of the structure as state variable andintensity as the objective function to optimize the danger section of the vehicle, weobtain the best optimal model size. Compare the optimization results with the originalcalculation results and verify the feasibility and importance of optimization design.Finally, combining with the Microsoft Visual Studio software developmentplatform, this paper consists with the finite element modeling, parametric analysis,results extraction and structure optimization and generate the operation interfacewhich makes it easier to use. Researchers barely need to input the parameters toautomatically accomplish the finite element analysis and optimization thus saving anamount of time. The research results can not only be used in concept design state ofseries models, but also be used to modify the original structure according to theresults of parametric analysis. Therefore this method effectively shorten the productdevelopment cycle and reduce the expensive cost of the overall research along withproviding useful guidance for domestic independent research of container truck.
