Description:
<jats:p>Floor vibration model was established by FEM and the modal analysis was conducted, which were based on the condition that this experiment took the automobile floor as the research object and applied the basic theory of finite element analysis. Simultaneously the results of modal analysis were compared with the results of the experiment, verifying the accuracy of the model. This can be considered as a basis of providing reference for the optimization and improvement of light bus floor.</jats:p>
