Abstract


Computer aided engineering(CAE) as an analytical technique has been used mor and more often and its CAD/CAE been paid more and more attention by people involved in the scientific and technological fields.This paper takes brushless DC motor(BLDCM) for the scope of research.,and puts engineering designing in the center,illustrating the use of CAE and its softwares in moter project.Taking advantage of CAD/CAE on the SolidWork plat and of its great usage to build complete CAE project of BLDCM.The article starts with the structure designing of the system of BLDCM to express the essentiality of CAE analysis. And researches the magnetic field、thermal field and structural strength simulated by computer with COSMOSWorks and COSMOSEMS inserted into SolidWorks,gaving the desinging and engineering analysis methods and complete solutions of CAD/CAE based on SolidWorks.After building 3D-models of a type of BLDCM and being on the base of this union of it,giving magnetic field、thermal field and strength analysis models.Applying load and restrict, then meshing and studying,it gives the magnetic field、thermal field and structural strength intuitionistic figtures.At the same time,we use the analytic method and numerical method to compute and analyze them,this not only proves the feasibility of designing and analysis with CAD/CAE softwares,but also ends to the improved designing method and thread.And as an example,the thermal field analysis gives the method of decreasing in loss.And based on the operating principle and design feature of CAD/CAE,it not only offers technical support to designing BLDCM,but also to developing new product and helps with performance analysistates.
