通过建立猎豹的骨骼肌肉系统的运动学模型,对猎豹奔跑过程中主要骨骼的运动过程进行标定,建立了单腿骨骼的机构模型;并测定各关节转角的变化规律,结合肌肉在前后肢骨肌系统内的附着位置,力臂变化特点,构建较为完善的骨肌坐标系统;最后,利用转角变化规律,驱动所构建骨肌坐标系统进行运动仿真实验,验证了所构建骨肌系统模型的正确性,同时得出猎豹高速奔跑时相关的运动特性,为生物力性能的研究奠定理论基础。
The kinematics model of cheetal muscle system was established to calibrate the movement process of main skeleton during cheetah running, and the mechanism model of one-legged skeleton was established. The changes of the rotation angle of each joint were measured, The system of attachment position, the characteristics of the force arm changes, to build a relatively perfect system of bone muscle coordinates; Finally, the use of the law of rotation, driven by the construction of the coordinate system of the bone muscle exercise simulation test to verify the correctness of the constructed model of the muscular system At the same time, the kinematic characteristics related to cheetah running at high speed were obtained, laying a theoretical foundation for the study of biomechanical properties.
