Experimental and Simulation study on Impact Faults and Vibration Characteristics of Gear Box

摘要

The finite element analysis and experimental measurement are used to study the vibration characteristics of gearbox impact faults. Parametric models ofrngearbox gear train are built through three-dimensional modeling software, and the finite element software transient dynamics module is used to analyze thernvibration acceleration response of the gearbox under different conditions of impact load. Compare the actual acceleration response which is collected fromrnfault simulation experiment with the finite element simulation results to verify the accuracy of the parametric models. Meantime, the vibration response ofrnthe gear box impact failure is analyzed, and the sensor layout optimization scheme is proposed, which reduces the blindness of vibration measuring pointrnarrangement and reduces the necessary channels for the monitoring and diagnosis. As a result, the cost of monitoring could be reduced.
