Dynamic response characteristic analysis of vehicle frame based on virtual simulation technology

Within this paper, the modality of vehicle frame is analyzed by finite element software of ALGOR, and carrying out the first 10 steps natural frequency resonance and vibration model. Using mode of two-degree-of-freedom vehicle vibration builds system's movement differential equation and simulates the frame's vibration by Simulink module of Matlab. Then make a dynamic response simulation for vehicle frame by the pavement incentive signal from pavement incentive simulation, at last, we can get the dynamic response characteristics of the vehicle frame in typical pavements, which may provide a theory basis for the frame structure's improvement and optimization.
