蟋蟀垂直攀登的微力测试及其动力学研究

Testing of micro-forces on vertical climbing crickets and dynamics research

用微力传感器测试了蟋蟀攀登的动力学特性,并与文献中壁虎的相比较,分析不同因素对攀登动力学特性的影响.结果表明,攀登时蟋蟀质心的壁反作用力表现出明显的周期振荡,质心循环向上加速,同时伴随从一侧到另一侧的运动.蟋蟀产生的攀登动力学特性类似于壁虎的,尽管它们的吸附机制、足形态和腿数量有所不同.

In order to give the common pattern of the diverse modes of climbing,a model for the dynamics of rapid and legged climbing was proposed.The influences of different factors on the dynamics model were analysed.Despite differences in attachment mechanism,foot morphology and leg number,vertically climbing crickets and geckos produce similar climbing dynamic behaviors.While climbing,the center of mass cyclically accelerates upward on the wall in synchrony with cyclical side-to-side motion.
