哈佛科学家发现篮球运动鞋的吱吱声 来自硬木上橡胶鞋底的有组织连锁波纹, 足迹模式产生高声响。
Harvard scientist finds basketball sneaker squeaks come from organized ripples in rubber soles on hardwood, with tread patterns creating high-pitched sounds.
哈佛材料科学家Adel Djellouli发现,篮球运动鞋的吱吱声来自橡胶底部的快速、有组织的波纹——就像快速移动的皱纹——因为它滑到硬木上,而像山脊一样的脚踏图则形成一致的、高压的声音。
A Harvard materials scientist, Adel Djellouli, discovered that basketball sneaker squeaks result from rapid, organized ripples—like fast-moving wrinkles—in the rubber sole as it slides on hardwood, with ridge-like tread patterns creating consistent, high-pitched sounds.
没有这种形态的平坦橡胶会产生混乱的波纹,没有噪音。
Flat rubber without such patterns produced chaotic ripples and no noise.
该研究使用高速照相机和麦克风,率先将这些快速摩擦脉冲与吱吱声直接联系起来,增进了对动态摩擦的理解,这种摩擦可能被用于地震建模、能源效率和未来鞋类设计,从而可以消除或调节声音。
The study, using high-speed cameras and microphones, is the first to directly link these fast friction pulses to the squeak, advancing understanding of dynamic friction with potential applications in earthquake modeling, energy efficiency, and future shoe design that could eliminate or tune the sound.
