论文摘要
我们在数值上研究了一个简单的滑动系统：一个由弹簧拉动的刚性质量，其平面内刚度各向异性和小错位角度。模拟表明，该系统中出现的明显棍子相实际上是一个非常缓慢的蠕变阶段，然后是快速滑动，滑动。令人惊讶的是，从棍子相的开始，摩擦力的绝对值几乎保持恒定，只是在滑动平面中旋转。由于力矢量旋转，我们称这种特定的明显棍子机制为“动态陈述”。
We numerically study a simple sliding system: a rigid mass pulled by a spring with a strong in-plane stiffness anisotropy and a small misalignment angle. Simulations show that the apparent stick phase appearing in this system is in reality a phase of very slow creep, followed by a rapid sliding, slip. Surprisingly, the absolute value of the friction force remains almost constant from the very beginning of the stick phase, merely rotating in the sliding plane. We call this specific mechanism of apparent stick due to rotation of the force vector "dynamic stiction".
