A new propeller automatic inspection method is developed to improve the R&D efficiency of the marine propeller.The method is based on the mechatronic simulation platform NX MCD to tackle the difficulty of real debugging and improper precision fluctuation in its modeling and simulation.Firstly,3D mechanical model is constructed and the mechatronic attributes are defined as the simulation ontology corresponding to physical parts according to the logic requirements.Then,an adaptive planning procedure of surface survey points is proposed based on mesh mapping.Finally,NX MCD,TIA portal,and S7-PLCSIM Advanced platform are connected to simulate PLC end control,real-time data interaction,and monitoring verification.In this way,virtual debugging in multiple fields of mechatronics is realized.Consequently,the feasibility of the proposed scheme is verified by simulation experiments,which provide a technical reference for the inspection of marine propellers and similar symmetrical free-form surface.
