In order to solve the problem of some cracks appearing in certain parts of the crankshaft for 6L21/31 diesel engine, the completed multi-rigid body virtual prototyping (VP) model of the diesel engine was established on the basis of the virtual prototyping technology, and the dynamics characteristic analysis was finished. Then, based on the completed flexible-rigid model of 6L21/31 diesel engine, the dynamic stress analysis of the crankshaft was accomplished, and the maximum stress value and its location were got. The results provided the basis for the improvement and optimization of the crankshaft.

Based on the rigid-flexible coupling virtual prototyping technology, the entities model of wheel loaders structural system was established by using Pro/E, then it was imported into the ADAMS environment and constraints were added to create a rigid model, and the corresponding rigid body was replaced by the model neutral file generated by ANSYS, thereby the rigid-flexible coupling virtual prototype was established. The speed and acceleration curve of bucket in a work cycle, the dynamic stress of link and the rear frame was achieved, and the dynamic characteristics of the bucket was analyzed. This paper can provide a reference for similar models of rigid-flexible coupling dynamics simulation.
