| Abstract: | The three-dimensional model of the vehicle aluminum alloy LNG frame that designed and produced by a machinery manufacturing enterprise was established by the SolidWorks software,and the modal analysis of the LNG frame was carried out through the simulation function of the software.The interaction bet ween the structure and excitation of aluminum alloy LNG frame was predicted,and the first 16 order modal frequencies and vibration modes of the aluminum alloy LNG frame were obtained.The results show that the aluminum alloy LNG frame can effectively avoid resonance when the vehicle is running normally.This analysis and opt imization method provides a reliable basis for the design and manufacture of the aluminum alloy LNG frame. |
