Open publisher page 0 citations

Abstract

To the frame of special vehicle for the study,the dynamic response of frame were analyzed which were in the outside world random vibration.The modal analysis and random vibration theory and method were put forward.The finite element analysis model was established.The modal and random vibration of frame were analyzed.The natural frequency,vibration mode and specific operating conditions the maximum displacement frequency response spectrum curve were obtained.The results offer reference for further studying the optimal design and new product development.
