| Abstract: | The dynamic characteristics is studied on the frame of heavy mining truck by using finite element method.This frame has been simplified in order to improve the finite element structural of the frame.Modal analysis is analyzed on the model by using the large finite element method software ANSYS.Some improvements have been carried on this frame by the results of modal analysis.The result of the technical improvement shows that low inherent frequencies and vibration shapes are optimized. |
