The mathematical models for the performance of aquatic animals developed by M Lighthill are compared with the experimental performance of a biomimetic fish. The equations developed by Lighthill are evaluated at steady-state conditions. Equilibrium velocity and mechanical efficiency are calculated using Lighthill's mathematical model and compared with experimental results. In both cases, a pattern is found wherein an optimum combination of tail frequency and amplitude maximizes equilibrium velocity. Differences between the theoretical and experimental results are attributed to mechanical limitations in the drive train.
将M·莱特希尔（M Lighthill）开发的水生动物性能数学模型与仿生鱼的实验性能进行了比较。在稳态条件下对莱特希尔开发的方程进行了评估。使用莱特希尔的数学模型计算平衡速度和机械效率，并与实验结果进行比较。在这两种情况下，都发现了一种模式，即尾鳍频率和振幅的最佳组合可使平衡速度最大化。理论结果与实验结果之间的差异归因于传动系统中的机械限制。
