我们开发了一个模型的波动运动的线虫，特别是秀丽隐杆线虫，基于力学，该模型考虑到最重要的力量作用于一个移动的蠕虫，并允许计算机模拟的爬行线虫。这些力是由充满液体的体腔内的内部压力、角质层的弹性、某些肌肉的兴奋以及身体与其支撑物之间的摩擦力产生的。我们提出，肌肉兴奋模式可以由牵张感受器控制产生。通过数值求解线虫模型的运动方程，我们证明了这些肌肉的激励模式是适合的动物的推进。
We develop a model of the undulatory locomotion of nematodes, in particular that of Caenorhabditis elegans, based on mechanics, The model takes into account the most important forces acting on a moving worm and allows the computer simulation of a creeping nematode. These forces are produced by the interior pressure in the liquid-filled body cavity, the elasticity of the cuticle, the excitation of certain sets of muscles and the friction between the body and its support.We propose that muscle excitation patterns can be generated by stretch receptor control. By solving numerically the equations of motion of the model of the nematode, we demonstrate that these muscle excitation patterns are suitable for the propulsion of the animal.
