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.

During type test experiment of loading mechanism, there exist a problem of deformation and cracking, in order to solve this problem, movement of cylinder under the action of gas source is analyzed by numerical simulation, based on this, use finite element analysis to execute dynamics simulation analysis, the effect of high-speed collisions when loading mechanism work it bring to cylinder bracket is analyzed, and the reason of cylinder bracket crack is find out. The modify method is put forward, it is proved by experiment that, after modify, the working reliability is significantly improved.

A model for virtual simulation analysis of the rigid-flexible coupling of a shearer has been developed with the objective of addressing problems associated with lifetime mismatch and low reliability of pin rows of a scraper conveyor and the corresponding support mechanism of a shearer. Simulations were performed using the experimental roller load as stimulus. Results of the analysis demonstrate that the vertical cutting force on the roller serves to reduce the load on the plane support plates during shearer cutting, and the force on the right plane support plate is considerably smaller compared to that on the left plane support plate along the direction of motion of the shearer. Owing to action of the roller-traction load, loads acting on the two guiding support plates increase significantly along the direction of shearer motion. Mechanical characteristics of the support mechanism were determined through experiments, and the accuracy of the virtual simulation model was verified. Simultaneously, mechanical characteristics of the shearer support mechanism were studied under varying pitch and roll angles. This study was performed to provide a base for analyzing the mechanical characteristics as well as optimizing the structural design of the shearer. Through fatigue-life analysis of the support plate and subsequent optimization of the support plate structure, the life of the guide support plate was found to have been extended by approximately 1.5 times.
