Structural Strength and Modal Analysis of a Certain Type of Heavy Vehicle Frame

This article make a research based on a certain type of heavy vehicle, In the research, we have made some analyses on structure reliability of the heavy truck with the assistance of some simulation platforms, such as computer aided design, finite element analysis, etc.. Based on the establishment of a correct finite element analysis model, analysis method is mainly about some research of the frame, such as typical working conditions of static analysis and modal analysis. Through these work, we can have a better understanding about the static and dynamic characteristic of the frame, so that we can find out the advantages and disadvantages of the car.
