Recent advances in computer technology have substantially changed the field of palaeontology in the last two decades. Palaeontologists now have a whole new arsenal of powerful digital techniques available to study fossil organisms in unprecedented detail and to test hypotheses regarding function and behaviour. Multibody dynamics analysis (MDA) is one of these techniques and although it originated as a tool used in the engineering and automotive industry, it holds great potential to address palaeontological questions as well. MDA allows the simulation of dynamic movements in complex objects consisting of multiple linked components. As such, this technique is ideally suited to model biological structures and to obtain quantifiable results that can be used to test the function of musculoskeletal systems rigorously. However, despite these advantages, MDA has seen a slow uptake by the palaeontological community. The most likely reason for this lies in the steep learning curve and complexity of the method. This paper provides an overview of the underlying principles of MDA and outlines the main steps involved in conducting analyses. A number of recent studies using MDA to reconstruct the palaeobiology of fossil organisms are presented and the potential for future studies is discussed. Similar to other computational techniques, including finite element analysis and computational fluid dynamics, the non‐invasive and exploratory power of MDA makes it ideally suited to study the form and function in vertebrates for which no modern analogues exist.

多体动力学分析(MDA)作为重建灭绝生物的功能和古生物学的数值建模工具

在过去的二十年中,计算机技术的最新进展已大大改变了古生物学领域。现在,古生物学家拥有全新的强大数字技术库,可用于以前所未有的方式研究化石生物并测试有关功能和行为的假设。多体动力学分析(MDA)是这些技术之一,尽管它最初是在工程和汽车行业中使用的工具,但它也具有解决古生物学问题的巨大潜力。MDA允许模拟由多个链接组件组成的复杂对象中的动态运动。因此,该技术非常适合于对生物学结构进行建模并获得可量化的结果,这些结果可用于严格测试肌肉骨骼系统的功能。但是,尽管有这些优势,MDA已被古生物学界缓慢吸收。其最可能的原因在于陡峭的学习曲线和方法的复杂性。本文概述了MDA的基本原理,并概述了进行分析所涉及的主要步骤。介绍了使用MDA重建化石生物古生物学的近期研究,并讨论了未来研究的潜力。与其他计算技术(包括有限元分析和计算流体动力学)相似,MDA的非侵入性和探索能力使其非常适合研究没有现代类似物的脊椎动物的形式和功能。本文概述了MDA的基本原理,并概述了进行分析所涉及的主要步骤。介绍了使用MDA重建化石生物古生物学的近期研究,并讨论了未来研究的潜力。与其他计算技术(包括有限元分析和计算流体动力学)相似,MDA的非侵入性和探索能力使其非常适合研究没有现代类似物的脊椎动物的形式和功能。本文概述了MDA的基本原理,并概述了进行分析所涉及的主要步骤。介绍了使用MDA重建化石生物古生物学的近期研究,并讨论了未来研究的潜力。与其他计算技术(包括有限元分析和计算流体动力学)相似,MDA的非侵入性和探索能力使其非常适合研究没有现代类似物的脊椎动物的形式和功能。
