论文摘要
追随者类型的非保守载荷通常被认为是动态不稳定性的来源，例如颤动和发散。结果表明，这些不稳定性（包括与耗散现象相关的HOPF分叉，扑动，差异，差异和不稳定的效果）可以在保守力量加载的结构系统中获得，这是由于非全面约束的应用。这些约束可以通过“完美的滑板”（或非滑动车轮），或者通常通过两个圆形刚性圆柱之间的无滑接触来实现，其中一个圆形圆柱体在其轴周围不旋转。这些动态不稳定性产生的结构的运动可能达到一个极限循环，该功能可以用于软机器人应用程序，尤其是用于实现有限损失的运动。
Non-conservative loads of the follower type are usually believed to be the source of dynamic instabilities such as flutter and divergence. It is shown that these instabilities (including Hopf bifurcation, flutter, divergence, and destabilizing effects connected to dissipation phenomena) can be obtained in structural systems loaded by conservative forces, as a consequence of the application of non-holonomic constraints. These constraints may be realized through a `perfect skate' (or a non-sliding wheel), or, more in general, through the slipless contact between two circular rigid cylinders, one of which is free of rotating about its axis. The motion of the structure produced by these dynamic instabilities may reach a limit cycle, a feature that can be exploited for soft robotics applications, especially for the realization of limbless locomotion.
