Application of Multi Body System Coupling Dynamic Model in Posture Stability Evaluation of Sports

Abstract

Due to the lack of more precise and complete data support, the reliability of posture stability evaluation method based on common technology is poor. In the face of such problems, the application of multi-body system coupling dynamic model in the evaluation of sports posture stability is proposed. The coupling dynamic model of human motion posture is established, and the relevant data of human motion posture is collected. The complete data of human motion posture is obtained by solving the dynamic model. Choose the appropriate stability evaluation index, calculate the stability evaluation index, divide the stability level, and realize the evaluation of posture stability. The experimental results show that: the application of multi-body system coupling dynamic model in the stability evaluation method makes the time delay and data error of the evaluation method small, and its overall reliability is improved.

Mechanical Analysis of Road Graben Slopes Based on Saturated-Unsaturated Seepage Theory

“…At present, based on rock-saturated-unsaturated seepage theory, Yang Xin used Go-studio finite element software to establish a numerical calculation model for high slopes containing soft and weak inclusions, and carried out a study on seepage characteristics at the top, middle and bottom locations of high slopes containing soft and weak inclusions in road graben under different rainfall factors [3]; Pan H proposed the utility of the Pan H proposed the software of the coupled dynamic mannequin of multi-body gadget in the comparison of action posture stability, mounted the coupled dynamic mannequin of human action posture and accumulated the applicable records of human action posture [4]; Xu Haitao et al used saturation-unsaturation theory to establish a coupled flow-solid model under rainfall infiltration conditions, obtained the distribution of the transient saturation zone and stress field of the cascade slope under different rainfall calendar conditions, and analyzed the damage mechanism of the cascade slope under continuous rainfall conditions, and obtained the corresponding safety factor of the slope [5]; Paul K et al proposed a strong cylindrical gap in a uniform magnetic subject appearing in the route of the axis of the cylindrical gap and the time scheme of the laser beam was once viewed non-Gaussian and acted on the floor of the cylindrical gap [6]; Yu Jinhui picked up the numerical simulation of the seepage characteristics of the high road graben slope under the effect of heavy rainfall by using the finite element calculation software, and obtained the change law of its internal seepage field, based on the principle of effective stress of unsaturated soil and the simplified Bishop method to obtain the change trend of the safety coefficient of the high road slope under the condition of heavy rainfall [7]; The new algorithm proposed via Rezaiee-Pajand M et al is in a position to pass by the load and displacement restriction factors of quite a number benchmark troubles with extreme nonlinear conduct and the proposed technique has the quickest convergence price in contrast to the regular plane, up to date everyday aircraft and cylindrical arc size techniques [8].…”
