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.

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.

As a device for time-delay, clock mechanism is widely used in fuze safety and arming device, whose core component is the runaway escapement. With the development of artillery systems, the dynamic environment during the projectile becomes more and more complicated. Recently, some shots misfire or premature explode during shooting process because runaway escapements’ miswork. This paper utilizes gear system’s research results applied in other fields, discusses clock mechanism’s dynamics problem, and uses ADAMS to analyze runaway escapement’s rigid-flexible coupling model. From comparing the simulation results of multi-rigid model and rigid-flexible coupling model, we find that elastic deformation will affect runaway escapement’s movement, even can cause the whole device to work abnormally.

AbstractWith the rapid development of gymnastics technology, novel movements are also emerging. Due to the emergence of various complicated new movements, higher requirements are put forward for college gymnastics teaching. Therefore, it is necessary to combine the multimedia simulation technology to construct the human body rigid model and combine the image texture features to display the simulation image in texture form. In the study, GeBOD morphological database modeling was used to provide the data needed for the modeling of the whole-body human body of the joint and used for dynamics simulation. Simultaneously, in order to analyze and summarize the technical essentials of the innovative action, this experiment compared and analyzed the hem stage of the cross-headstand movement of the subject and the hem stage of the 180° movement. Research shows that the method proposed in this paper has certain practical effects.
