摘要
基于周期性栅结构修饰的声学硬薄板,研究了位于结构板上方的黄铜球体粒子所受到的声辐射力、粒子位置和粒子尺寸对声辐射力的影响.仿真结果表明,当外部声波入射到该非开口硬薄板体系,铜粒子与结构板的距离小于0.5d时,铜粒子将受到声拉力而被捕获,声辐射力密度随粒子尺寸的减小而增大.这种违反直觉的声拉力源于周期性结构硬薄板中无泄漏兰姆波模式所引起的集体激励.
We investigated the acoustic radiation force(ARF)acting on a spherical brass particle near a stiff plate without openings but patterned with periodic stubs.Simulation results showed that the particle near plate which the distance is less than 0.5 dcan be pulled backward when external acoustic waves impacted into the system.And the ARF will decrease when the size of the particle increases.We also demonstrated that the dramatic pulling force originates from the collective excitation of nonleaky flexural lamb modes in the periodically structured solid plate.
