规范骑行参数化建模的应用与实践

针对骑行者骑行姿势不规范的问题,提出了一种用于规范骑行的参数化建模方法.首先,创建人体模型和自行车模型,定义底层参数、中间层参数和高层参数,实现模型参数化;其次,对骑行过程进行受力分析,建立动力学模型,保证虚拟骑行符合自然运动规律;最后,建立人体上下肢参数与自行车参数间约束关系,实现人体关节协调运动.对骑行过程进行运动仿真,实验结果表明,该方法能够为骑行者提供正确的姿势指导.

Application and Practice of Parametric Modeling for Standardized Riding

In order to correct the nonstandard riding postures of riders, a parametric modeling method for realizing standardized riding is proposed. Firstly, a manikin and a bicycle model are created, and parameters of the bottom layer, middle layer, and high layer are defined, so as to realize model parameterization. Secondly, force analysis during the riding is carried out, and a kinetic model is established, so as to ensure that the virtual riding conforms to the natural motion law. Finally, the constraint relationship between human upper and lower limb parameters and bicycle parameters is established to realize the coordinated movement of human joints, and the motion during the riding is simulated. The simulation results show that this method can provide correct posture guidance for riders.
