Abstract
In this study, the inverse kinematics mathematics computer intelligent algorithm model is used to study the sports injuries of the elbow joint of adolescents. At the same time, we simulated the movement parameter changes during the rehabilitation training of the patient's wrist and proposed a joint angular velocity function based on cubic fitting. Research has found that when the training scene changes greatly or the target task is changed, the smoothness of the elbow joint movement will change. The research conclusions of this article provide a theoretical basis for the selection of man-machine action points and the formulation of rehabilitation training methods. This article establishes the degree-of-freedom simulation model of the operating arm, which is the number of independent position variables in the operating arm, and these position variables determine the positions of all parts in the mechanism.

Summary
Establishing an accurate kinematics model of the mechanism is the primary issue in the research process of the bionic manipulator structure. According to the established equations, the simulation analysis of the changes of the pneumatic muscle length is under different motion trajectory conditions [4]. A virtual prototype of the mechanism is constructed based on the pseudorigid body model, and a simulation system model of the pneumatic muscle bionic elbow joint is built.
