观察到由于边界表面之间的接触的破坏和随后的恢复而引起的界面弹出非线性的阈值启动。结果表明，在小接触压力下，将观察到不稳定性以及通过连续多个分叉或边界振动周期的演变而产生的混沌振动。还表明，当接触界面表面之间存在略小于振动幅度的初始间隙时，可能会出现与振动 fre 接触表面碰撞相关的方波爆裂非线性。
The threshold initiation of popping nonlinearity of the interface as a result of the breaking and subsequent restoration of contact between the boundary surfaces is observed. It is shown that instability and the generation of chaotic vibrations by evolution of successsive multiple bifurcations or the period of the boundary vibrations will be observed at small contact pressures. It is also shown that a square wave popping nonlinearity associated with collisions of the vibrating fre contact surfaces can occur when an initial gap slightly smaller than the vibration amplitude exixts between the surfaces of the contact interface
