摘要：Based on geometry models of vehicle components,a rigid-flexible coupling
   virtual prototype of a certain tracked armored vehicle was constructed
   by vehicle body finite element model meshing and modal analysis.After
   the multi-body dynamics simulation of the prototype under several
   typical driving conditions,the loads acting on the vehicle body at
   several typical moments were exported and imposed on the body finite
   element model.The structural mechanics analysis and multi-load steps
   topology optimization of the body structure were carried out.According
   to the optimization results,local structure of the body was modified.A
   new virtual prototype was constructed by the improved body and the
   simulation was executed again,from which the stress and deformation
   results of the body were got.Comparison with the original results shows
   that the structure topology optimization technology which combines
   dynamics simulation with finite element analysis can improve the
   mechanical properties of the key components,enhance the stiffness and
   strength,which provides an effective means to improve the structural
   performance of armored vehicle.
