基于测量的运动数据的人体步态的计算机模拟是生物力学中的一项成熟技术。然而，优化研究需要许多迭代步态周期模拟尚未发现广泛的应用，因为它们的高计算成本。因此，一个计算效率高的逆动力学模型的三维人体步态的设计和等效模型相比，使用商业多体动力学软件包创建。本文中描述的快速逆动力学模型导致执行速度提高了8倍。提供了足够的细节，以允许读者自己实现该模型。
Computer simulation of human gait, based on measured motion data, is a well-established technique in biomechanics. However, optimisation studies requiring many iterative gait cycle simulations have not yet found widespread application because of their high computational cost. Therefore, a computationally efficient inverse dynamics model of 3D human gait has been designed and compared with an equivalent model, created using a commercial multi-body dynamics package. The fast inverse dynamics model described in this paper led to an eight fold increase in execution speed. Sufficient detail is provided to allow readers to implement the model themselves.
