Dynamic Optimization of Rotation Angle of Joint Rotator in Multi-Functional Sports Training Device

In order to effectively improve the overall performance of the multi-functional sports training device,it is necessary to optimize the rotation angle of its important component joint rotator.Therefore,a dynamic optimization method of rotation angle of joint rotator based on dynamics is proposed.The multi-functional sports training device is composed of joint rotator,circular central frame,protective equipment and motor transmission equipment.At the same time,it explores its internal principle and training advantages.The right angle coordinate system is established to display the relationship between the human body and the joint rotator,and the azimuth value of a certain object in space is obtained to complete the motion control of the joint rotator.Combined with the principle of dynamics,the dynamic equation of upper limb rotation is studied,and the rotation angle derivation model of joint rotator is constructed,and the optimal range of rotation angle is determined.The simulation results show that the proposed method can greatly reduce the friction coefficient of joint rotator,make the joint rotator use state more flexible,and achieve the goal of stable and safe use of multi-functional sports training device.
