构象转变驱动下小型游泳运动员的力学响应

Mechanical Response of a Small Swimmer Driven by Conformational Transitions

Ramin Golestanian, Armand Ajdari

摘要:

建立了一个构象空间动力学模型,以驱动三球游泳器在低雷诺数下的变形循环来实现推进。我们分析了外部负载的性能上的影响,这个动力游泳者,并表明,它敏感地依赖于力施加的地方,所以没有一般的力-速度关系。我们讨论了如何构象周期的游泳者应设计,以增加他们的性能,在特定点施加的阻力。

英文摘要:

A conformation space kinetic model is constructed to drive the deformation cycle of a three-sphere swimmer to achieve propulsion at low Reynolds number. We analyze the effect of an external load on the performance of this kinetic swimmer, and show that it depends sensitively on where the force is exerted, so that there is no general force--velocity relation. We discuss how the conformational cycle of such swimmers should be designed to increase their performance in resisting forces applied at specific points.
