为机械工程设计的多体软件多年来已成功地应用于生物医学研究。对于实时操作，一些生物医学研究人员也采用了游戏物理引擎。然而，这些工具是为其他目的而建造的，并没有完全满足生物医学研究人员使用它们来分析生物结构的动力学并提出临床上有意义的建议的需求。我们正在通过开发一个开源的、可扩展的、高性能的工具包来解决这个问题，其中包括一个旨在满足生物医学研究人员需求的多体机械库。由此产生的代码Simbody支持各种领域的研究，包括神经肌肉、假肢和生物分子模拟，以及相关研究，如仿人机器人和化身的生物启发设计和控制。SimBody是OpenSim背后的动力学引擎，OpenSim是一个广泛使用的生物力学模拟应用程序。这篇文章回顾了在生物医学研究中独特出现的问题，并报告了Simbody用来解决这些问题的体系结构、理论和计算方法。通过明确地解决这些需求，SimBody提供了比机械工程或游戏代码改编更好地匹配研究人员的需求。Simbody是一个社区资源，对于任何目的都是免费的。我们鼓励广泛采用，并邀请对https://simtk.org/home/simbody.代码库的贡献
Multibody software designed for mechanical engineering has been successfully employed in biomedical research for many years. For real time operation some biomedical researchers have also adapted game physics engines. However, these tools were built for other purposes and do not fully address the needs of biomedical researchers using them to analyze the dynamics of biological structures and make clinically meaningful recommendations. We are addressing this problem through the development of an open source, extensible, high performance toolkit including a multibody mechanics library aimed at the needs of biomedical researchers. The resulting code, Simbody, supports research in a variety of fields including neuromuscular, prosthetic, and biomolecular simulation, and related research such as biologically-inspired design and control of humanoid robots and avatars. Simbody is the dynamics engine behind OpenSim, a widely used biomechanics simulation application. This article reviews issues that arise uniquely in biomedical research, and reports on the architecture, theory, and computational methods Simbody uses to address them. By addressing these needs explicitly Simbody provides a better match to the needs of researchers than can be obtained by adaptation of mechanical engineering or gaming codes. Simbody is a community resource, free for any purpose. We encourage wide adoption and invite contributions to the code base at https://simtk.org/home/simbody.
