Research On Overhead Crane Parameter CAE Analysis Method In Network Environment

With the rapid development of the national economy, the market demand of overheadcrane is increasing year by year, and the business requirements tend to be varied, personalised,short-cycle, high efficiency and high reliability. As an emerging technology, parametric CAEtechnology has become the focus of many scholars, which can realize product rapid designverification and reliability analysis.In the paper, 75t-125t overhead crane is taken as study object, in the multi-user machine,dual-server, multi-workstation network environment, Solid Edge ST3 and Femap V10.0 aretaken as development platform, overhead crane parametric CAE is studied intensively fromtwo aspects of the bridge crane CAE model method and parametric CAE analysis method.Establishment method of overhead crane CAE model: on the basis of discoursingparameter CAE modeling techniques theory, CAE model is divided into geometry shapecharacteristics and finite element characteristic, the geometry shape of CAE model isestablished by using Solid Edge, and the technical problems about parameter-driven in theload application location and programmed identification unit numbers automatically aresolved through the surface segmentation. VB is used to develop secondary Femap V10.0,CAE model building method of finite element characteristic and discretized CAE analysismodel are studied. CAD/CAE mixture model library which is compatible for CAD design andCAE analysis at the same time is established.Parameterized CAE analysis method of overhead crane: on the basis of overhead cranemodule division and design calculation, programmed analysis knowledge, parameterized CAE analysis method of overhead crane based on Femap platform is proposed and studied. VB isused to develop secondary Solid Edge, simplify model and drive parameters of the geometriccharacteristics template of CAE mode to generate the required geometric characteristic model.VB is used to call relevant interface function of Femap. The method and process of CAEanalysis pretreatment, analysis calculation and post-processing are parameterized,standardized and programed. Parameter CAE analysis of overhead crane is finally realized.According to the study for theory and method, overhead crane Parameter CAE analysissystem is established in the Femap platform, and, on the basis of characteristics of eachmodule, the system is installed on user machine, server and workstation, which make theproduct design resources and computer resources be fair used.The system has been used in overhead crane analysis process in an enterprise, andreceived good effect, which improved CAE analysis efficiency and quality, shortened productdevelopment cycle.
