Abstract: In order to solve the engine drop failure of a heavy-duty diesel engine transport support in shipping, the pre-processing software Hypermesh and the finite element analysis software Abaqus are used to complete the model construction and simulation research on the failure parts, and the causes of the engine mount support and transport support falling off are analyzed. The results show that the amount of slip between the transport support and the engine mount support exceeds the limit, resulting in the rupture of the connecting bolt between the mount support and the transport support. In this paper, a new type of integrated transport support is designed for the situation of slip over limit, and the calculation results show that the new scheme meets the design requirements in all aspects.
