Building a dataset through attack pattern modeling and analysis system

Objectives: With the rapid development of sports biomechanics, a new frontier discipline, the modeling and Simulation of human motion, as one of the cutting-edge research topics of sports biomechanics, is receiving more and more attention.. Methods: Based on this, this paper provides theoretical support for the analysis and research of foot stress in the process of training and applies it to guiding practice by using the analysis technology based on sports biomechanics and the method of foot pressure and simulation modeling and analysis system. Results: The results of the study showed that the injury of the athletes in the lower limbs accounted for about 46.7%, followed by the injury of the upper limbs and the injury of the trunk. In the lower extremity injury, the most common part of the foot joint is about 28.1%. Conclusion: Studies have shown that the changes in the force of the athlete’s foot after fatigue have not had the good stability before, the duration of each stage of the completion of the movement is changing, and the control of the ankle joint is decreasing, which greatly increases the foot joint. The possibility of injury.

In Japan, the seismic design methods for structures are developed in the civil and architectural fields. And these seismic design technologies have also been brought to mechanical structures such as piping facilities and boiler structures, etc.. But, for the geometric time varying structure of which geometric configuration is dependent on time such as cranes, the kinetic and the dynamic characteristics of such structures are not fully considered in the seismic response analyses. In this paper, we try the modeling of the geometric time varying structure systems by means of the method of multibody dynamics. And we examine the effect of the geometric time varying system on the seismic response. The beam elements formulated by the absolute nodal coordinate are used to model the structure that has large displacement motion of the base of the structure. The crane structure for the building construction is modeled in the numerical example. The seismic responses of the moving boom part of the crane model are simulated. New phenomenon has been explored.

In this paper, by defining and associating the boom structure parameter characteristic of truck crane, we build a parameterized automatic analysis system of truck crane boom, based on the VB platform with the ANSYS APDL language. In the system, the basic parameters of the crane structural finite element analysis can be obtained by human-computer exchange, achieving the finite element automatic modeling and analysis of boom structure under the driving of the parameters. Engineering examples show that the system is reliable and accurate results.
