Abstract: In order to avoid complicated pretreatment setting of finite element analysis of shearer parts, reduce threshold of the finite element analysis and improve efficiency of finite element analysis of shearer parts, a parameterized CAE analysis method of shearer parts was studied and developed by use of UG secondary development tool and VS2012 programming software. The system can directly make the parameterized CAE analysis of the shearer parts in UG software, directly call pretreatment dialog box to set before finite element analysis, and directly call calculating solver by program to complete analysis process, so as to realize the parametric CAE analysis of key parts of shearer, avoids data loss in data conversion by different softwares, and improves analysis efficiency. The effectiveness of the system is verified by an example.
