In order to solve the problems of difficulty in force analysis and modeling of rhythmic gymnastics technical movement joint muscles and low precision in force quantitative evaluation, a finite element-based numerical simulation analysis model of rhythmic gymnastics technical movement joint muscles was proposed in order to realize quantitative analysis of force parameters of rhythmic gymnastics technical movement joint muscles.The non-linear kinematic homogeneous decomposition method is adopted to obtain the analysis of the technical joint muscles of the human body rhythmic gymnastics in buffer exercise.The finite element analysis method is adopted to model the mechanical model of the technical joint muscles of rhythmic gymnastics.Under the limited initial state and combined with the constraint conditions, the stress state model of the technical joint muscles of rhythmic gymnastics can be obtained, and the stress numerical simulation of the technical joint muscles of rhythmic gymnastics can be realized.The simulation results show that the numerical simulation of joint muscle stress in rhythmic gymnastics using this method has high accuracy and the quantitative analysis results are accurate and reliable.
