To study the structure of one ship type dump truck carriage, stress and displacement distribution analysis is conducted for static full load lifting.It is provided the basis for the improvement and optimum of the structure,and some corresponding improvement plans were proposed. Compared the analysis results before and after improvement, the results show that the strength and stiffness of the carriage is improved after improving the local structure, the research and practice of this paper possess certain practical significance and referential value in the design of such a dump truck carriage structure.
