In view of the above problems, the main research contents of this paper are as follows: First of all, through the deep analysis of the actual production of the original fixture problems, bined with the structure of the fixture design, find out the main problem of the originai fixture designing,namely,radial positioning precision and fixture and blank gateinterference. Secondly, aiming at the problems radial location of fixture design, this paper carries on the optimization design of mechanical optimization design from the fixture of the original radialpositioning fixture. Then, through the ANSYSWorkbench software, it has the static analysis and modal analysis of the new fixture. verify the rationality and safety of the designing, the maximum stress,displacement and theweakest find new fixture structure, and optimize the structure. Keywords: aluminum wheel hub。 static analysis。modal analysis。 the finite element simulation 目 錄 III 目 錄 摘 要 ...............................................................................................................................
