Modal Analysis of the Frame of the Light Electric Sanitation Vehicle
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 10
Abstract
Aiming at the complex modal characteristic of the frame of the light electric sanitation vehicle under various working conditions, the finite element method is used to study the natural frequency and modal shape cloud diagram. Based on the frame model established in the three-dimensional software, the model characteristic is analyzed, the natural frequency and modal shape of the first five orders of mode are obtained, and their influences on vehicle travel are analyzed. The frame is improved, and the influence of the improved frame on the natural frequency and modal shape are analyzed. The results show that the bending and torsion resistance of the improved frame is ameliorated. Compared with the torsion resistance, the bending resistance of the frame is much ameliorated, which lays a foundation for the relative experiment, dynamics analysis and structural improvement of the frame.
