In the process of aero-engine assembly,some parts will have significant deformation due to assem-bly stress,and it is necessary to accurately predict the deformation caused by assembly,which requires that the deformation of parts in the manufacturing state and the assembly state should be considered in the three-dimen-sional modeling.In the framework of NX software,two kinds of modeling methods of deformation parts are de-veloped,namely parameter driven and multi-reference set expression,which can meet the model requirements of manufacturing state and assembly state.Before the model is created in the two states,the deformation parame-ters are analyzed according to the deformation characteristics,and the parameter-driven or multi-reference set representation modeling method is selected to complete the 3D solid modeling.
