本工作采用55自由度的骨骼数字人体模型来模拟人体搬运。基于优化的方法用于预测对称和不对称负载的承载运动。在此过程中，模型使用优化方案和基于任务的物理约束来预测关节动态。结果表明，该模型可以预测对称和非对称承载任务期间的不同承载策略。该模型还可以指示极端负载情况的风险因素。凭借如此强大的预测能力，该模型可用于生物医学和人体工程学研究。
Human carrying is simulated in this work by using a skeletal digital human model with 55 degrees of freedom. An optimization-based approach is used to predict the carrying motion with symmetric and asymmetric loads. In this process, the model predicts joint dynamics using optimization schemes and task-based physical constraints. The results indicate that the model can predict different carrying strategies during symmetric and asymmetric load-carrying tasks. The model can also indicate the risk factors for extreme loading situations. With such robust prediction capability, the model could be used for biomedical and ergonomic studies.
